Where Does This Leave Us?
Inter-city mass transit
Possible Rail Network
Where we are today
in 2012- 726 bicycle deaths due to bicycle/motor vehicle collisions (7.5% increase from 2001)
in 2012- 49,000 bicycle injuries (8.9% increase from 2001)
Integrating bikes with transit
Where to go
Improving Infrastructure/Making more mainstream
bike racks/parking for bikes
promote bike culture
create open source information
bicycle priority in cities
Easy to fix
Buses and trollies
-Avg. passenger capacity 100-300
-Single-decker, double-decker, articulated,
non-articulated, 40ft., 80ft.
-Trollybus, cable cars, aerial tramway
Fuel consumption (U.S. bus fleet)
18.6% compressed natural gas (CNG)
8.8% hybrid electric diesel
64.4-64.7 % diesel
Transition to Alternatives
Average initial investment:
U.S. market cost of diesel= $290,000
U.S. market cost of hybrid= $500,000
30-74% higher for hybrid buses.
Short/long term maintenance costs.
Sustainability concerns with industry alternatives
Hybrid buses rely on extractive metal markets
Hybrid bus batteries are only partially recyclable*
CNG buses rely on non-renewable extracted fuel
Tramways, trollybuses, cablecars, and grid-connected transport networks currently being supported in China.
Solar inter-vehicular power source.
3.5% overall increase bus ridership 2007-2008
Out of 130 million US workers- 5% use mass transit
In eleven largest cities 25% use public transit
(Tony Favro/Citymayors.com, 2009)
Highest overall demographic demand for buses comes from minority groups, recent immigrants, and lower income residents
Youth/young adult bus riders
Average annual miles per driver in 16-34 yrs. 22,722mi
Average annual miles per driver in 35-64 yrs. 27,263mi
(Federal Highway Administration)
Why buses and subways?
Increase transport choice, affordability, safety, and efficiency for riders
Efficiency and density
One-way streets, bus lanes, bus boulevards.
Synchronized traffic lights: precise engineered timing,
video surveillance, bus-light sensor systems. (Emily Clark, gizmag.com, 2008)
Increased speed, better public perception, more bus and subway riders.
Decreased road expansion means decreased car congestion. (Roseland, 2012)
Social capital considerations
Land-use is important for transportation- something past city planning did not consider.
We have roads, we might as well use them- for mass transportation, pedestrians, and bicyclists.
Still keeping in mind not all citizens will immediately switch over to mass transit.
Increasing bus customer comfort and convienience
Solar bus shelters, safe ride times, children family senior and differently-abeld fee waivers, bus apps, commuter perks and preference.
When considering bus routes, use community supported planning, prioritize pedestrians (bus stops close to the public sphere and destinations).
ICEV (Internal Combustion Engine Vehicles)
Direct Fuel Injection
Homogeneous Charge Compression Ignition
BEV (Battery Electric Vehicles)
HEV (Hybrid Electric Vehicle)
Hydrogen Fuel Cell
Auto-centric paradigm effects:
Sustainable transportation offers:
Affordability and accessibly
More modes of transportation
Why Sustainable Transportation?
Bring new urbanist ideas for implementation in rural communities. (e.g. BART bus in Ashland, WI)
"The lack of either economic or social self-containment is natural and necessary to city neighborhoods– simply because they are parts of cities." (Jacobs, 117)
The Death and Life of Great American Cities
Mass transit as a corridor for social capital
Drop of 23% MPD in 16-34 yrs. from 2001-2009 and 6% fewer average miles driven comparing 2011 to 2004 (Davis, Dutzik, Frontier Group 2012).
(U.S. Department of Transportation)
Currently improving speed of subways.
(APTA Factbook Glossary)
Under city streets- freeing space for other alternative modes of transit. Avg. capacity 100-300 per car.
