The Center for Transit Oriented Development

A project of Reconnecting America in collaboration with Center for Neighborhood Technology, Strategic Economics and local partners. Exec Director: Shelley Poticha

A collaborative, performance based approach to making TOD succeed

Create a national marketplace for TOD, working with transit operators, developers, investors and communities.

“Bring TOD to scale” in 4-5 metro regionshttp://www.reconnectingamerica.org

Principles for Making Transit Compete

To succeed, passenger transport must emulate the qualities associated with the auto: frequency, reliability, speed, convenience, & ease of use.

Page 4: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Frequency

Next to accessibility,most important factor is frequency of service. Goal is service frequencies that don’t require reliance on schedules.

Page 5: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Reliability

This may be the Achilles heel of the car, as incident related congestion reduces predictability of the commute.

Means that transit must separate itself from the auto environment where possible.

Page 6: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Speed

Finding and promoting corridors where public transport can better the auto in travel time while providing a less stressful environment is effective.

Transit prioritization, separated guideways, reduced transfers all are strategies here.

Page 7: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Convenience

Stations should be accessible to the pedestrian, inviting.

Rider serving amenities near station reduce need to drive: child care, groceries, cleaners.

Page 8: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Ease of Use

Accessible fare instruments: U pass, annual pass, available through employers.

Low-floor vehicles, identifiable stops.

Fixed guideways reduce uncertainty

Individualized marketing

Western Australia is a leader with TravelSmart; Australian Greenhouse Office has promoted concept.

Getting to households at key points to offer individualized information about travel choices.

A note about modes

Much time is wasted in the debate about bus or rail: both are needed, and it depends on setting.

If goal is development impact, developers want competitive travel time, identifiable station, high quality design.

Urban Subway

Suitable for downtown areas, very expensiveEntrance is just a stairway on the streetCan be integrated into buildings

Page 15: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Segregated Guideway At Grade

Separated from traffic, can be faster, less conflictMore expensiveLess accessible, less suited for local circulation -- usually railroad ROW -- may not be in dense areasWorks well in suburban locations, and where rail right of ways is available

Page 16: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Freeway Alignment

Faster running timeCheaper landFreeways not very compatible with town centers, pedestriansMost suitable for commuter rail, access to suburbs

Page 17: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Elevated Guideway

Elevated guideways are an intrusion into the urban formStations can be seamless: just another storefront

Options for Street Running

Street Running in Center Alignment

Allows creation of station areas, requires a lot of street widthPedestrians must cross through traffic to get to stopDowntown to suburban

Page 20: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Street Running, Either Side Alignment

Better transit-pedestrian interfaceMost suitable for downtown urban circulation where access trumps speed

Page 21: Transit and Sustainable Urbanism: Shelley Poticha & Hank ... · Shelley Poticha & Hank Dittmar CTOD/Reconnecting America Text. The Center for Transit Oriented Development A project

Street Running, One Side Only

May reduce confusion with auto traffic

Simplifies pedestrian crossing

Works well to increase speed outside downtown, amounts to separated guideway

Next Steps

Create TOD complement for each transect zone, and link typology to transect for each street type.

Develop a manual for transit/street/urban design interface, incorporating such issues as performance of different technologies (turning radius, stopping distance, operating speed), street performance for all classes of users (suggested by Peter Calthorpe.)

CNU/CTOD transit and urban design summit/ Charter Council early 2005 to gather designers working with transit and urban design to develop common language, tools and frameworks for transit at all scales in the region.
