getting ready for winter

If you have a property with a garden, you’ll be familiar with the list of things you do every year to get things tidy and safe before it freezes up out there. We face the same kind of to-do list along our construction zones on Highway 7 and Davis Drive, although the key difference is we’ll still be actively working throughout the winter (I’ll tell you more about what we’ve got planned for the winter months in an upcoming post).

But in terms of getting things all tidied up, here’s what you’ll see us doing over the next couple of weeks to get ready for the snow and ice.

Our top priority, as always, is making the construction zones as safe as possible for pedestrians and drivers.  For that reason much of our pre-winter activity involves ensuring that sidewalks and boulevards are free of hazards, and hazards that cannot be removed are carefully fenced off.  In some cases we’re finishing the grading and construction of some boulevards, and in others installing temporary walkways and ramps where work isn’t scheduled to be finished until next year.

Snow fences are being installed behind sidewalks in areas where work is continuing, to help mark the safe route for pedestrians.  And because of ongoing roadwork and other activities, some sidewalks will remain closed.  We’ll make sure there’s a clear route for pedestrians through work zones, although it may require crossing from one side of the street to the other. Look for directional signage to know where it’s safe to walk, and how to access bus stops – for your own safety it’s critical that pedestrians stay out of work zones.

During construction, road and sidewalk maintenance is the responsibility of the construction contractor within the project areas.  But during the winter, the Region and local municipalities are responsible for ensuring the roads and sidewalks are kept clear. For that reason, another top priority before winter is to ensure every aspect of the construction zones is compatible with the requirements for winter maintenance operations.

This means making sure the snow-clearing equipment can manoeuver through the construction zones, boulevards and platforms.  Our design work and construction staging plans have always had those requirements top of mind, but we walk through the sites with Regional and municipal staff again before winter to identify any little details that might impede their operations.

And to keep traffic moving throughout the winter, we’ll be taking steps to make travel lanes as straight as possible through the construction zones, and ensure markings are clear.

Just like at your home, we like to get everything tidied up and in order before winter, so we’re going to keep working steadily at it until we’re forced to stop by severe winter weather.  Once that happens, we have a long list of other activities we will continue with, so stay tuned.

happy national housing day

Having a home is probably one of the most important and basic needs people have, and National Housing Day was introduced to remind us we should never take this fundamental need for granted.  This year National Housing Day is Friday November 22, and it’s being marked by special initiatives all across the country including here in York Region, where the Region is hosting a special social media and web-based campaign to raise awareness about the importance of affordable housing.

One of the biggest challenges facing our Region is that people have limited choice when it comes to affordable housing.  Traditionally a suburban region, many York Region residents have chosen to live in low-density single-family homes. As wonderful as that choice is for many, many families, there are some people who want – or need – other options.  And until recently, people who wanted to live in other forms of housing had very limited choices within the Region.

York has the lowest percentage of rental accommodation in the entire GTA. In some cases, that has meant people who want to live in York Region to stay near their families, or their jobs, have had to move away.  Whether it’s a young professional in their first job who has had to leave York Region to find affordable housing, or an older person who can’t manage a larger home on their own any more, too many people have found it hard to stay here at home.

Fortunately that’s changing, and VivaNext is a key driver that’s helping to expand the housing choices available here in York Region.

All along the viva routes, we’re seeing more and more housing being developed or proposed, including higher density developments near our new urban centres. Taking the direction from Regional Council, 35% of new housing in the centres and key development areas along the corridors have to meet affordability criteria, which is going to meet a key need here in York Region.

Building residential units along transit can help to reduce housing costs, since developments don’t have to include as much underground parking spaces.  This can reduce costs per unit significantly.  Another benefit of building near transit means people can get around without needing a car.  Whether you’re a young person moving out for the first time, or an older person who is happy to give up the keys to the car, that’s a significant advantage.

The best thing is that people who want to stay in York Region are now more able to, because rapid transit and long-term planning together are resulting in more choices, and more affordability.

So on November 22, give a thought to how much it would mean to you to be able to stay in the community you love, and to have a variety of affordable options to choose from.  We’re really pleased to be helping make that more possible, and wish you a Happy National Housing Day.

clearing the way for construction

If you’ve ever watched a new subdivision get built, you know how fast the work seems to advance.  Crews install utilities, build rough roads, and before you know it there’s an entire subdivision ready for families.  But building a new roadway in a densely built-up area is a completely different challenge: the work seems to go on for a long time, and progress is hard to detect unless you know what you’re looking for.

We’ve been working flat-out on Davis Drive for a year now, with dozens of complex activities underway or completed from Yonge to Leslie.  Even so, most of our effort so far has been about clearing the way, rather than constructing a rapidway and stations.

That’s the predictable reality of modernizing our roads and revitalizing Newmarket’s infrastructure, but it’s worth explaining why we can’t get going on roadway construction until these steps are completed.

A key work priority has been to build retaining walls to enable the road widening along the hilly contours of Davis Drive,  with that work now nearing completion.

And like all major thoroughfares, the foundations of the existing Davis Drive roadway are literally lined along both sides with existing critical infrastructure carrying water, telecommunications, gas, storm sewers and sanitary sewers.  Much of this infrastructure crosses the road at intervals and in many cases the various utilities are stacked up in multiple layers.  In addition, at the sides of the road are hydro poles and lines, transformers for electricity and telecommunications, fire hydrants, and a whole range of privately owned signs for businesses and commercial buildings.

As much as we love getting to the stage of putting down asphalt and constructing the beautiful viva stations, we can’t start this until the right-of-way is completely clear. Once we’ve built the retaining walls, we need to relocate everything else, one element at a time, further back and out of the way of the new wider roadway.  Relocating utilities is a complex task in itself, requiring a highly detailed level of coordination between gas, hydro, telecommunications and other utility companies.

Each type of utility has its own specific requirements about how and where it can be relocated, and which one goes deepest, which has to be installed last, and so on.  Each element requires its own program of design work and approvals.  And lastly, different crews are responsible for specific utility relocations, and there are rules about how closely they can work relative to adjacent work crews.

So the job of getting the roadway clear for construction is a huge, time-consuming and enormously detailed process – without even considering the new bridge and retaining walls that are underway. With multiple activities to be carried out in each block, some people may wonder why we’re not progressing more quickly.  But the reality is that we’ve already completed much of the work needed to clear the roadway, and widening has already started in some segments.  Because so much of the work is underground, there isn’t much to see yet.  But as crews start paving, it will feel and look like progress is starting to take shape.

Even though building a rapidway is a long process, people along Highway 7 in Richmond Hill and Markham can attest that the transformation does come to fruition. Residents and visitors alike are now enjoying the Highway 7 rapidway. We look forward to the day the Davis Drive rapidway is complete and Newmarket can enjoy the finished result too.

bringing vaughan metropolitan centre to life

We recently posted a great blog on planning that talked about the link between transit and new urban communities. Given that tomorrow (November 8), urban planners from towns and cities in over 30 countries worldwide will celebrate World Town Planning Day, we thought we would take a moment to highlight another one of York Region’s amazing communities, and see how vivaNext transit projects fit into York Region’s planning vision.

In the Region’s Centres and Corridors strategy, selected areas in Newmarket, Richmond Hill, Markham and Vaughan are targeted to have new, urban “downtowns.” They will be vibrant, higher density, attractive destinations with a full range of amenities so that people can live, work, shop and play in the same community. These “centres” will be connected by transportation “corridors” that will make it easier for people to get around the region. That’s where we come in. Our vivaNext rapidways will run along the corridors, connecting the centres through transit and safe and efficient travel options for pedestrians, motorists and cyclists alike.

You can see the vision for one of these centres coming to life in the City of Vaughan’s new video about the Vaughan Metropolitan Centre [VMC] . Located in the heart of Vaughan, centered on Highway 7, between Highway 400 and Creditstone Road, VMC will be one of the largest and most ambitious development projects in the area’s history, and is a superb location for Vaughan’s new downtown.

In the VMC, mixed-use transit-oriented development is proposed along a tree-lined main street, including businesses, residences, entertainment and cultural facilities, as well as pedestrian shopping areas. The VMC area will act as a transportation hub, including convenient passenger pick-up and drop-off, a York Region Transit bus terminal, and viva rapidways running in dedicated lanes along Highway 7.

VMC will also be home to the northernmost subway station, as part of the Toronto-York Spadina Subway Extension [TYSSE], an 8.6 km subway extension from Downsview Station, northwest through York University and north to the Vaughan Metropolitan Centre. An entrance to VMC Station will be built on Millway Avenue, between Edgeley Boulevard and Jane Street to provide easy and efficient connections to other transit services.

With approximately 442 acres of development opportunities, VMC also includes:

  • Projected office development: 1.5 million SF
  • Projected retail development: 750,000 SF
  • Minimum of 12,000 residential units
  • Population potential: 25,000 new residents
  • Employment potential: 11,000 jobs of which 5,000 will be office jobs

It’s exciting to visualize how Vaughan will evolve in the years to come. To find out more about other vivaNext projects, visit our projects page.

working together….

If you get vivaNext email updates, you probably recently read that Yorkie and Torkie the tunnel boring machines are munching their way closer and closer to Highway 7 and the Vaughan Metropolitan Centre (VMC).

This is great news, and means that the reality of a subway coming to York Region is getting closer every day.  But while the tunneling project is very high profile, vivaNext is also working hard to get ready for the subway opening at our VMC station.   Unlike other vivastations which we are building independently, the VMC station construction needs to be closely coordinated with the subway project, adding a whole new level of complexity.  Here’s a little background:

The VMC station will be located at Millway Avenue and Highway 7, as part of the VMC development area.  To provide passengers with seamless connections between the subway and the viva\YRT system, the subway station will be located on the lower level, with a concourse linking the subway to the vivastation above.

That may all sound relatively straightforward, but in fact there are significant engineering challenges involved with constructing a complicated building in the middle of a live highway, especially  when there’s a separate construction project going on directly underneath.  One of our top priorities is to ensure while we’re building the station to our own design plans, it also ties in to all the complex TTC systems down below so that everything works properly and in sync.

Some key elements such as escalators, elevators and stairways link the two structures. These need to be in place so the TTC can access the upstairs while they’re building their subway station down below. Escalators and elevator shafts aren’t very forgiving, so we need to work closely together to make sure all the elements line up perfectly.

Another challenge is that there’s not a lot of space to work given the location of the station in the middle of Highway 7.  From time to time we’re literally going to be working right on top of each other.  So we will be doing a lot of coordinating throughout the process to make sure all our contractors and subcontractors have enough room to do their jobs safely and in parallel.

The main priority for vivaNext and the TTC is that both parts of the VMC station are open when the subway service begins.  There’s a huge amount of work to be done between now and then, and we’ll be working closely with our TTC partners during the course of construction.

So stay tuned, and soon I’ll be giving you a proper tour of the VMC station design.  It’s going to be a showpiece that will be worth all the hard work.

what is a culvert anyway?

 

I’m guessing that you probably weren’t thinking about culverts as you sipped your coffee on your commute through the construction this morning — probably not even if you passed right by one. But let me just take a moment to tell you why culverts are important – besides the obvious.

First of all, what is a culvert anyway? Well, I’m sure you’ve seen one by the side of the road, underneath a driveway, around creeks and rivers. A culvert is a tunnel or pipe of varying size, shape and material used to allow water  to move easily from one side of an obstruction (like a road or railway) to the other side.

A culvert has three main functions: to allow for stream crossing; to manage and direct water runoff; and to allow natural wildlife crossing. The first two are pretty self-explanatory, but where it gets interesting is the wildlife crossing.

Since culverts affect both animals and the environment, the Ministries of the Environment, Natural Resources and Transportation have set out specific standards for culverts. Those standards note that they must be constructed in such a way to allow any wildlife travelling through them to see light at the other side. And culverts must include material that mimic the natural landscape of the wildlife passing through it to encourage them to use the culvert for migration.

The typical lifespan of a culvert is somewhere between 10-20 years, depending on a number of factors. When water flows through a culvert frequently, as it does at eastern and western creeks in Newmarket, the culvert will naturally succumb to some erosion. With our plans to widen Davis Drive for the rapidway, we are extending the western creek culvert and removing and replacing the eastern creek culvert that was well beyond its lifespan.

It’s just one more component of an overall transformation towards vibrant urban centres, connected by a rapid transit network to help people get around.

vivaNext – more to come

When it comes to the future of transit in York Region, you don’t have to look far. The first rapidway along Highway 7 east corridor is now up and running smoothly. With it came wide pedestrian-friendly boulevards, lined with trees and other greenery. The transformation taking place along the Viva routes will change how pedestrians, cyclists and motorists not only view the area in general, but get from A to B more easily, more safely and more efficiently.  Check out this 3600 virtual tour for a peak.

This is just the beginning of many miles of rapidway that are under construction or coming soon.  Here is an update of what’s happening.

Construction on Highway 7 East continues and crews are working hard from Highway 404 to Warden Avenue to widen the road, build pedestrian boulevards, plant trees and shrubs as well as installing utilities. This next segment of rapidway is expected to be completed in 2014.

Moving along Highway 7 west to Vaughan, you will see the vivaNext rapidway construction starting to take shape between Edgeley Boulevard and Bowes Road.  Over the last few months, crews have been working to remove signs, test soil and begin utility relocation to prepare for heavier construction.  Throughout the fall and winter, hydro, gas and telecommunications installations and relocations will continue in Vaughan.

Preliminary construction activity will also continue in other parts of Vaughan as vivaNext rapidway construction continues along Highway 7 West.   The Vaughan Metropolitan Centre [VMC] station will be completed in time with the Toronto-York Spadina Subway Extension [TYSSE].  Vaughan’s VMC station will be the northernmost subway station, connecting to Viva and a variety of other transit services, for a convenient and seamless experience.

In Newmarket, as you drive or walk along Davis Drive, you’ll see that construction is in full swing and the transformation is starting to take shape. The relocation and replacement of underground infrastructure in some segments on the south side of Davis Drive is complete. In those sections, road widening and preliminary paving has started preparing the roadway for future rapidways.

Also in Newmarket, crews are working to re-locate the Historic Union Hotel and its adjoining building to their final foundations this fall. Extensive culvert work at eastern and western creek is underway.  Work continues on the north side of the Keith Bridge.  Once completed all this work will help make your travel along Davis Drive smoother and more efficient, especially if you are on transit!

Over the next few years, future rapidways will be added to the Viva routes to better service customers and make travel times shorter by up to 25%.  We know construction is messy, but the end results are marvelous!

colour coding the rapidway

As I’ve posted previously, Bus Rapid Transit is an increasingly popular rapid transit technology around the world [Bus Rapid Transit: growing around the world, Bus Rapid Transit: South America leads the way].   One of the ways to make BRT truly rapid, as we’re doing here in York Region, is to provide vehicles with separate lanes so they can move easily through congested areas.  And one way to make those lanes distinct without having an actual grade separation (which would require extra room as well as be much more costly) is to make them a different colour.  This is why the vivaNext rapidways are bright red, as you’ll have seen if you’ve driven along Highway 7 East recently.  These red lanes are for viva transit vehicles only and cars need to be careful not to drive into them for everyone’s safety.

But colouring asphalt anything other than basic black isn’t as easy as you might think.  Here’s what we’ve done to get our rapidways red.

Painting asphalt isn’t an option. Although it’s something we all take for granted, creating a long-lasting, durable asphalt mix for the conditions along a busy roadway like Highway 7 is actually a highly specialized science.  The surface on roadways that carry a lot of heavy traffic, especially traffic that is constantly turning and braking or accelerating at intersections, needs to be exceptionally strong to prevent cracking, rutting and shifting.  Canadian climate conditions including extreme temperature changes, hot sun, frost, and salting over the winter, all impose significant challenges.  Creating an asphalt mix to take these conditions without requiring frequent maintenance is something that specialized pavement designers work long and hard to achieve, with the technology constantly evolving.

So adding in the requirement to make it a distinct colour definitely adds to the complexity.

Using red pavers or bricks would not provide a sufficiently durable driving surface long term, and would be extremely costly to install and maintain.  One approach that is used when the colour is needed in very limited areas, such as crosswalks or bike lanes, is a material called “street print”.  But this material, which is actually a special top layer that’s heated right into the asphalt once it has been imprinted with a brick or paver pattern, would be too complicated to use along the full length of the rapidways (although we are using it for our crosswalks), and again would not be durable enough.

So the best approach is to tint the black asphalt, which we’re accomplishing in a couple of ways.   Asphalt is composed of a mixture of sand, stones and asphalt cement binding it together.  By adding reddish stones rather than grey ones, we can give an underlying red tint to the asphalt, especially as it wears.

The more complex adjustment is to add a special red pigment.  The challenge with the pigment is to be careful in how much we add:  too little and the colour doesn’t come through, but too much and the overall durability of the asphalt might be compromised.  The pavement design team has worked long and hard through a highly technical process to get the balance just right.

We’re delighted with their final results, which will give us what we need: a clearly defined rapidway that stands out from the regular traffic lanes, with a long-lasting and durable surface, at an affordable price.  Drivers need to remember as they make turns from side streets along Highway 7 to follow the white skip lines and not turn onto those red rapidways!  Although beautiful, they are red for safety too!

the communications brain behind our rapid transit system

In other posts I’ve talked about the various ITS components behind our Bus Rapid Transit along Highway 7. But none of these pieces would be able to do its job without being connected to the others through a sophisticated fibre optics communications system.  Although it’s hiding underground, this communications system is really the unsung hero that’s going to put the rapid in our rapid transit system.   Here’s how it’s going to work.

As I’ve described before, there are several transit priority measures that will help viva vehicles on the new Highway 7 rapidways run smoothly and quickly through congestion.  These include on-board components on each vehicle including a GPS system and transmitters.  There are also the components at each intersection that help each traffic signal respond to changing traffic requirements including radio and infrared receivers that pick up signals from approaching buses and emergency vehicles, and loop detectors in the roadway that detect cars waiting at the intersection.  Lastly, there are the variable message signs (VMS) located at each platform that provide next-bus arrival information to customers.

As high-tech as each of these components is, none can be effective unless it can communicate with the others.  Each one also needs to be connected to the overall transit system which keeps track of the schedule for each bus, and which determines when the traffic signal phasing requires a temporary adjustment to let a delayed bus get back on schedule.

The connection is provided through a fibre optics communications network that links all of the intersection and every vivastation to YRT’s transit operations and York Region’s traffic operations.

This system is fully automated, with approaching vehicles alerting intersections that they are arriving, and each intersection sharing that information with the central traffic control system, which in turn compares that information with the transit schedule.  The system will continuously adjust and fine-tune to ensure the buses stay on schedule, while keeping the roads and intersections working well for everyone.

To enhance passenger safety, each station is equipped with cameras to monitor the platforms, a public address system to provide announcements and an emergency call box for personal safety.  All of these systems operate reliably and seamlessly over the fibre optic communications system.

By using fibre optics technology running the entire length of the corridor, we’ll be able to collect all this information and transmit it quickly so that the transit system can respond immediately.  The communication system will also provide the real-time bus arrival information displayed on station VMS.

With this high-tech communications system providing the brains to the transit system, viva will make it easier, faster and more reliable to travel across York Region.  Check out this video on how this system works.

ITS – balancing the needs of all travellers

It’s stating the obvious to say that our roadways are getting slower because they’re carrying too much traffic – that’s the basic definition of gridlock, and it’s an increasing problem everywhere across the GTA.  But what can be done about it?  VivaNext is one part of the solution – if people have the choice of taking a reliable and convenient rapid transit system, there will be fewer cars on the road, and everyone will be able to get around more quickly.

But even with vivaNext, there’s still going to be a lot of traffic out there, and York Region doesn’t have room for more or bigger roads.  So what else can be done to help traffic move better?  This is where ITS comes in.

Although some people may think ITS is connected to “Information Technology”, in the vivaNext world ITS stands for “Intelligent Transportation Systems”. ITS is an international transportation-engineering discipline that is concerned with trying to improve the efficiency of travel, whether it involves the travelling public, commercial vehicles, or transit.  The basic assumptions behind ITS are that delays cost money, and more efficient travel saves money. This new technology is an absolutely critical, although low-visibility, component of the vivaNext program.

ITS is used to ensure that all parts of a traffic corridor’s infrastructure – the physical roadway’s design, lane markings and signs, traffic signal design and timing, and the brains that connect all these pieces – are designed as one coordinated system.  In a transit project ITS has an additional layer which is concerned with how the transit system is integrated into that larger system.

ITS is also about giving people accurate information so they can make better choices about travel, whether that means building roadside signage to alert drivers to upcoming congestion and suggest alternative routes, or giving transit riders real-time information about next bus arrivals.

Overall, ITS is about finding the perfect balance so that all the users of a roadway find it works better; making a roadway faster for one group of users cannot come at the expense of all the other users.  ITS starts with an understanding of who is using the roadway now and who will be using it in the future, and then develops strategies to make it more efficient for everyone.

Along Highway 7, we know that drivers and transit are the main users currently, but that’s going to change as development intensifies. The future Highway 7 will be significantly more urbanized, with more people living and working along the corridor.  That means there will be more pedestrians and cyclists whose travel needs need to be considered, in addition to car and truck traffic.  Helping transit vehicles stay on schedule is also a priority, since rapid transit can’t be rapid if it’s stuck in traffic.

These ITS strategies will balance everyone’s needs, to help everyone get to where they’re going as fast as possible!
