What is the problem?

How did we get here?

Where is congestion from?

■ Cities have faced congestion for a centuries

– As cities succeed in attracting people from other places,

congestion occurs

– Congestion is an economic issue: demand > supply

How have we dealt with congestion?

■ Western cities historically addressed traffic like sewage

– The first Western traffic engineers were sanitation engineers

– Gravity models atomistic travel demand models

– Fluid dynamics vehicle flow

■ Traffic engineering approaches were institutionalized

– Travel demand models to predict

– Design standards to help provide

– Metrics to measure performance

■ The institutions have been biased and incomplete


What are transportation institutions?

1. Trip Generation

(pop & jobs by zone)

2. Trip Distribution

(gravity model)

3. Mode Split

(fn trip type, income…)

4. Route Assignment

(based on travel times)

What is the problem with performance measures?

What are the results of this approach?

■ Roads are widened &

designed for fast traffic

■ Cities are still congested

■ Places are auto-oriented

■ Can’t go places without car

■ Injury, emissions, inactivity &

isolation

■ Worst impacts on the poor,

people with disabilities,

seniors & children

Is there another way to deal with transportation problems?



Is there another way to predict demand?

Connected

Cities

Destinations in Silicon Valley


■ Where are:

– jobs?

– services?

– people’s homes?

■ Are destinations

– connected to each

other?

– walkable?

– concentrated around

transit?

Adaptive Cities

e.g. Stockholm, Copenhagen, Tokyo, Singapore

Why do we need rapid transit?

■ Santa Clara County will add 600k residents, 300k jobs by 2040

■ Which mode do we want for additional trips on El Camino Real?

What is Bus Rapid Transit (BRT)?

■ Unique branding

■ Widely-spaced “station stops” with amenities

– realtime bus arrival information

■ Good ped/bike connections

■ Coordination with connecting services

■ Signal timing, signal priority, queue jump

■ Frequent service

■ Low-floor, multi-door boarding

■ Off-board fare collection

■ Dedicated lanes

What are the BRT proposals & impacts for El Camino Real?


Alphabet Soup and El Camino Real

Nelson\Nygaard Consulting Associates, Inc. 18

■ Regional agencies (MTC/ABAG) developed Plan Bay Area

2013

– Plan Bay Area identified Priority Development Areas (PDAs),

including El Camino Real

■ VTA is pursuing a BRT project on El Camino Real

– Releasing DEIS, October 2014

– Presenting locally preferred alternative, February 2015

■ Grand Boulevard Initiative (GBI) recognized VTA’s El

Camino BRT project 2013

– Revitalize El Camino Real

– Create nodes for economic and housing opportunities

– Create walkable, bikeable,

transit-friendly Complete Street

Alternative 1: Do Nothing

Nelson\Nygaard Consulting Associates, Inc. 19 Source: VTA 2014

VTA’s estimate impacts of Alternative 1: Do Nothing

■ Transit quality: speeds & on-time reliability decline

■ Transit ridership: grows with population and jobs

■ Auto speed & capacity: unchanged, road retains same feel

■ Safety: No improvements

■ Cost: $0 (capital) + $0.8 million (operating)

■ Farebox recovery: no change


Alternative 2: Mixed Flow


Alternative 3A: Do Nothing / Mixed Flow+


Alternative 3B: Mixed Flow+


VTA’s estimate impacts of Alternative 2: Mixed Flow

■ Transit quality: 9% faster than Do Nothing

■ Transit ridership: grows 4% faster than Do Nothing

■ Auto speed & capacity: unchanged, road retains same feel

■ Safety: Curb bulbouts shorten crossings at stations

■ Cost: Measure A (capital), $1.9 million saving (operating)

■ Farebox recovery: grows $0.9 million

VTA 2014

Alternative 4A: Partial Dedicated Lanes


Alternative 4B: Partial Dedicated Lanes


Alternative 4C: Full BRT


VTA’s estimate impacts of Alternative 4: Dedicated Lanes

■ Transit quality: 80% faster, frequent, reliable

■ Transit ridership: grows 23% faster than Do Nothing

■ Auto speed & capacity: 7% slower, route shifting in peak

■ Safety: Bike lanes, shorter & new signalized crossings

■ Funding: Msr A + $75M FTA (capital), $7M saving (operating)

■ Farebox recovery: up to $1.5 M

What now?


Where to now?

■ We all have an opportunity to participate in the production

of space and the future of El Camino Real

■ Participate in the planning process, talk with leaders and

people in your community

■ Consider the values with which we plan this space:

– Ecological sustainability?

– Social inclusion?

– Economic dynamism?
