York Region BRT signal priority could transform travel times across the network
YORK REGION — If recent transit projects across the Greater Toronto Area have shown anything, it’s this:
Signal priority is not optional — it’s essential.
From the rollout of the Finch West LRT (Line 6) to the launch of the Eglinton Crosstown (Line 5), one issue has consistently shaped rider experience:
How transit vehicles move through intersections.
And now, that same question is becoming increasingly important in York Region — where Bus Rapid Transit (BRT) already plays a major role in the network.
The Reality of “Rapid” Transit
York Region’s BRT network — particularly along Highway 7 — is designed to move large numbers of people efficiently through dedicated lanes in the middle of the road.
On paper, it’s rapid transit.
But in practice, it doesn’t always behave like it.
At many intersections, BRT vehicles still wait for:
- Left-turn traffic
- Right-turn lanes
- General vehicle movement
Only after those movements clear do transit vehicles receive a green light.
That sequence slows everything down.
And it raises a critical question:
Can transit truly be “rapid” if it is still waiting in line?
The Case for True Signal Priority
The solution is not complicated — but it does require a shift in thinking.
Transit should go first.
If a BRT vehicle is approaching an intersection, signal systems should be designed to:
- Give transit immediate or early green priority
- Allow turning movements after transit clears
- Then release general traffic flow
This is what “true signal priority” looks like.
And it’s how BRT systems in leading global cities maintain speed and reliability.
Why It Matters
Signal priority is not just a technical upgrade — it’s a performance multiplier.
Implementing full priority across York Region’s BRT network would:
- Reduce travel times across long corridors
- Improve schedule reliability
- Increase ridership confidence
- Maximize the value of existing infrastructure
Because the infrastructure is already there.
The question is whether the system is being used to its full potential.
Lessons from Finch and Eglinton
Toronto’s recent transit launches offer a clear lesson.
On the Finch West LRT and parts of the Eglinton Crosstown, conditional or limited signal priority has led to:
- Slower-than-expected trips
- Frequent stops at intersections
- Frustration among riders expecting rapid service
These are not construction problems.
They are operational decisions.
And they show what happens when transit is not fully prioritized.
A Regional Opportunity
York Region has an advantage.
Its BRT network is already established, with dedicated lanes, modern stations, and strong ridership potential.
That means improving performance doesn’t require new construction.
It requires better signal control.
By upgrading to full transit priority, York Region could:
- Set a new standard for BRT in the GTA
- Deliver faster service without major capital investment
- Strengthen connections across Vaughan, Markham, and Richmond Hill
Balancing the Network
Of course, signal priority must be implemented carefully.
Intersections must remain safe for:
- Pedestrians
- Cyclists
- Turning vehicles
But prioritizing transit does not mean eliminating these movements.
It means sequencing them more efficiently.
Moving the most people first.
The Bigger Picture
As the GTA continues to invest in transit — from subways to LRT to BRT — one principle is becoming increasingly clear:
Infrastructure alone does not guarantee performance.
How the system is operated matters just as much.
York Region’s BRT network is a strong foundation.
But without true signal priority, it risks falling short of its full potential.
Build It — Then Optimize It
The Finch West LRT has shown the cost of partial priority.
York Region now has the opportunity to get it right.
Not by rebuilding infrastructure
But by improving how it works
Because at the end of the day:
Rapid transit that waits at red lights is not truly rapid.
