The Big Picture: How Networks and Space Efficiency Create a Better Philly for Everyone
And how a more livable Philly is better for its bottom line
TL;DR: Philly faces two transportation realities: we can't fit more cars, and disconnected bike/transit infrastructure doesn't work. The solution? Commit to complete networks of space-efficient transportation that create a virtuous cycle of less congestion, easier parking, and better mobility for all.
Over the past couple weeks, I've written about two fundamental transportation truths:
Philly's spatial geometry means we physically can't accommodate more cars
Disconnected, piecemeal bike/transit infrastructure fails to create meaningful alternatives
These aren't separate issues – they're two sides of the same coin. Today, I want to connect these dots and paint the bigger picture of what a sensible transportation future looks like for our city.
Where We Are: The Downward Spiral
Right now, we're caught in a vicious cycle:
We design streets primarily for cars
This makes alternatives unsafe/inconvenient
So more people drive
Creating more congestion
Which makes buses slower and less reliable
So even more people drive
Rinse and repeat
Each year, we try to squeeze more cars into the same limited space, like trying to stuff another Angelo’s pizza box into the only trash can for 6 blocks around. Continuing like this, you’ll have to wade through a load of garbage to get anywhere.
Meanwhile, we build the occasional bike lane that ends abruptly at a dangerous intersection. We run buses that sit in the same traffic as cars. We create pedestrian plazas that are surrounded by hostile roadways.
And then we wonder why these half-measures don't magically transform our transportation system or spark joy for our residents.
The Vision: A Virtuous Cycle
Now imagine a different approach – one where we acknowledge both spatial reality and network effects:
Step 1: Identify key transportation corridors
Where do people need to go and where are they coming from?
What routes connect major destinations?
Which streets have the width to accommodate multiple modes?
Step 2: Design complete networks, not isolated projects
Continuous, protected bicycle routes that connect neighborhoods
Dedicated bus lanes on major corridors
Safe, comfortable pedestrian paths throughout
Step 3: Implement systematically, not piecemeal
Build connected segments that create usable routes from day one
Measure success by network performance, not individual project metrics
Don't stop halfway – commit to completing connections
This approach creates a virtuous cycle:
Complete networks make alternatives viable
More people choose alternatives for some trips
This all reduces congestion for those who need to drive
Which makes the entire system more efficient
Real-World Examples of Success
This isn't theoretical – cities similar to Philly have already proven it works:
Seville, Spain
Built an 80km connected bike network in just 36 months
Cycling mode share jumped from 0.5% to 7% almost immediately
Traffic congestion dropped 15% citywide
Paris, France
Implemented "15-minute city" concept with connected bike/pedestrian networks
Removed 70,000 parking spaces to create protected bike lanes
Traffic decreased 45% since 2000 while mobility improved
Boston, Massachusetts
Created connected bus priority corridors
Bus travel times improved 25-40% on these routes
Ridership increased 30% on improved routes
Each of these cities committed to complete networks of space-efficient transportation, and each saw dramatic improvements not just for cyclists and transit users, but for drivers too.
What This Means for Philly's Streets
Let's get specific about what this could look like here:
East-West Connections We need at least 3 continuous, protected crosstown routes in Center City – not just Spruce and Pine with their faded paint and constant delivery truck blockages. Real, physical separation from traffic that maintains continuity through intersections.
North-South Connections Instead of sharrows on 13th Street (which are just passive-aggressive reminders that cyclists exist), we need physically protected lanes connecting South Philly to North Philly neighborhoods.
Transit Priority Dedicated bus lanes on major arterials like Broad, Market, Roosevelt Boulevard, and Frankford Ave. Not just during rush hour – all day. With camera enforcement to keep them clear.
Neighborhood Slow Zones Traffic calming that makes residential streets safe for walking and biking without needing dedicated infrastructure. Things like raised crosswalks really are the stuff of paradise once you experience it.
The Benefits for Everyone
Here's where it gets good – this approach actually helps everyone:
For Drivers:
Less congestion from unnecessary car trips
More available parking when short trips shift to other modes
Clearer designation of where driving is prioritized
Less time wasted in traffic
For Transit Riders:
Faster, more reliable service
Better connections between modes
More frequency as ridership increases
Less crowding as service improves
For Cyclists:
Safe, connected routes to more destinations
Less stress from navigating dangerous gaps
More company on the roads (safety in numbers)
Better infrastructure maintenance as usage increases
For Pedestrians:
Shorter crossing distances
More sidewalk space
Less traffic noise and pollution
More vibrant street life
For Businesses:
More customer capacity (bikes and transit bring more people using less space)
More pass-by visibility as people move at human speeds
More disposable income as transportation costs decrease
More attractive streets that draw visitors
The Path Forward: Breaking the Deadlock
Getting from here to there won't be easy. The politics of street space are contentious, and change is hard. But we can start by:
Changing how we measure success
Person throughput, not vehicle throughput
Network connectivity, not miles of infrastructure
Access to opportunities, not travel speed
Committing to complete networks
No more bike lanes to nowhere
No more bus improvements that end at district boundaries
No more pedestrian improvements surrounded by dangerous roads
Focusing resources strategically
Better to have five great, connected corridors than 20 incomplete ones
Target investments where network effects are strongest
Build on existing assets and complete missing links first
Being honest about space constraints
We cannot accommodate more cars – full stop
Every transportation decision is a space allocation decision
The most efficient uses of space should be prioritized
The Bottom Line
Philadelphia doesn't have a congestion problem – it has a space allocation problem. We're using our limited street space inefficiently, and no amount of traffic engineering magic can overcome basic geometry.
At the same time, we're squandering opportunities to create viable alternatives by building disconnected fragments instead of functional networks.
The solution is to bring these insights together: build complete networks of space-efficient transportation options. This isn't about being anti-car – it's about being pro-math and pro-reality.
For those who genuinely need to drive, nothing would improve their experience more than having other viable options for those who don't. For everyone else, having real choices beyond driving would transform daily life.
Let's stop the piecemeal planning and commit to a transportation system that works within Philly's spatial reality – one that creates complete networks of efficient options. Our streets can work better for everyone, but not if we keep pretending we can fit unlimited cars into limited space.
Let's make getting around Philly suck less – by working with our city's reality, not against it.
P.S.: Pro tip for our esteemed Mayor and Council: Make Philly great to live in, and you won’t have to worry about businesses, residents, and investment leaving the city. Make it possible for residents to get around, then you can figure out the suburbanites’ conundrum. When people want to be here, businesses do, too.
