Consequences Avg. annual hours of congestion delay per person grew from 11in 1982 to 26 in 1999 at a cost of $77.8 billion. 36 U.S. regions with 85 million people fail to meet national st in addition to ards as long as ozone. Transportation sector contributed 513 million metric tons of CO2 in addition to accounted as long as 18% of global oil consumption in 2000. The policy dilemma Should policies focus on accommodating growing levels of VMT because thats apparently what the public wants to do Should policies focus on limiting VMT so as to reduce environmental in addition to other costs The alternatives! Improvements in vehicle in addition to fuel technology to reduce environmental impacts without limiting driving. But that doesnt solve everything! Reduce the need as long as driving by enhancing accessibility rather than mobility. Planning as long as Accessibility!
Accessibility, mobility, whats the difference CAMPO 2025 Regional Transportation Plan: The primary goal of the CAMPO 2020 Plan is to provide an acceptable level of mobility in addition to accessibility as long as the regions residents with the least detrimental effects. Accessibility, mobility, whats the difference CATS 2020 Regional Transportation Plan: Provide an integrated in addition to coordinated transportation system that maximizes accessibility in addition to includes a variety of mobility options that serve the needs of residents in addition to businesses in the region. Accessibility, mobility, whats the difference TEA-21: Increase the accessibility in addition to mobility options available to people in addition to as long as freight
Accessibility vs. Mobility Mobility is the potential as long as movement Accessibility is the potential as long as interaction Good Mobility Ability to move around Poor Mobility Inability to move around
Good Accessibility Ability to get what you need Choice of destinations Choice of modes Poor Accessibility Inability to get what you need No destination choices No mode choices Accessibility vs. Mobility Good mobility usually contributes to good accessibility, BUT You can have good accessibility with poor mobility You can have poor accessibility with good mobility
The Problem In most places in the U.S . Accessibility is mobility-dependent Mobility is car-dependent That has implications as long as Persons who cant drive Quality of life as long as those who can Planning as long as Mobility Focus on the means, not the end: Maximize movement Emphasize vehicle needs Implications as long as communities: Encourages sprawl Limits choices Built into st in addition to ard per as long as mance measures Planning as long as Mobility
Planning as long as Accessibility Focus on the ends, not the means: Maximize interaction, satisfaction Emphasize person needs Implications as long as communities: Encourages alternatives to sprawl Exp in addition to s choices Requires new per as long as mance measures Planning as long as Accessibility Strategy Options Mobility-Enhancing Strategies Road building ITS Accessibility-Enhancing Strategies L in addition to use strategies ICT Mobility-Limiting Strategies Pricing Road restrictions
Mobility-Enhancing Philosophy Metropolitan regions need more highways in addition to freeways to serve growing populations We should respect the desire of the majority to use their cars Adding capacity will reduce congestion in addition to its impacts ITS – Intelligent Transportation Systems From in as long as mation in addition to automation Roads Cars Transit Freight Evidence on New Capacity Recent studies on induced travel: UC Berkeley study: 10% increase in capacity leads to 9% increase in traffic Others: 10% increase in capacity leads to 4.7% to 12.2% increase in traffic Nol in addition to in addition to Cowart: capacity increases account as long as 15% of VMT growth annually Induced travel offsets improvements in congestion, air quality, in addition to other impacts
Evidence on ITS TransGuide reduced accidents by 15% in addition to emergency response time by 20% in San Antonio (TxDOT) Advanced Traveler In as long as mation System led to changes in route, departure time, confidence in Seattle (Volpe) Smart Ramp as long as HOVs in addition to buses saved 8.5 – 19.2 minutes per week per user in Portl in addition to (Lall & Lucas) Long-term effects not yet clear Who supports this strategy Road building Departments of Transportation The road lobby The majority of the public Most of the politicians Who supports this strategy ITS Technology believers Many of the leading transportation engineering researchers Industry, esp. defense-related industry Most of the politicians
Accessibility-Enhancing Philosophy L in addition to Use Strategies By designing communities more like they used to be, we can reduce auto dependence Neighborhoods should include a commercial center Neighborhoods should be linked by a regional transit system Interrelated ideas New Urbanism Transit-oriented development Downtown revitalization Smart growth Infill development Preservation
So to conclude Adopt accessibility-enhancing strategies to provide choices Adopt mobility-limiting strategies to encourage choices that reduce VMT The BIG question Just how much mobility can we rightly expect in addition to dem in addition to The growing Response Dont we have a right to the freedom not to drive, too
