Safer Than You Think! Revising the Transit Safety Narrative
Public transportation is overall safe (low crash risk) and secure (low crime risk), with about a tenth the traffic casualty (death or injury) rate as automobile travel, and residents of transit-oriented communities have about a fifth the per capita traffic fatality rate as in automobile-oriented communities. Transit also tends to have lower crime rates than automobile travel, and large, transit-oriented cities tend to have low crime rates. However, many people consider transit dangerous and are reluctant to use it or support transit service expansions in their communities. Public transit agencies can help create a new transit safety narrative that better communicates transitís overall safety and health benefits.
Factors to Consider When Estimating Congestion Costs and Evaluating Potential Congestion Reduction Strategies
Traffic congestion can be measured in various ways that result in very different conclusions about the nature of the problem and optimal solutions. This article, submitted to the ITE Journal, describes various factors that affect congestion cost estimates and the evaluation of potential congestion reduction strategies. It discusses how these factors influence planning decisions, and describes best practices for comprehensive evaluation of congestion impacts.
Local Funding Options for Public Transportation
This report, to be published in the Journal of Public Transportation, evaluates eighteen potential local public transit funding options according to eight criteria. This is a somewhat larger set of options, and more detailed and systematic evaluation, than most previous studies of this type. The overall conclusion of this study is that a variety of funding options should be used to help finance the local share of transportation improvements to insure stability and distribute costs broadly.
Autonomous Vehicle Implementation Predictions: Implications for Transport Planning
This report investigates how autonomous (self-driving) vehicles are likely to develop, and their implications for transportation planning. It identifies autonomous vehicle benefits and costs, their functional requirements, and when these impacts are likely to become significant.
Congestion Costing Critique: Critical Evaluation of the 'Urban Mobility Report'
The 'Urban Mobility Report' (UMR) is a widely-cited study that estimates traffic congestion costs. This report critically evaluates its methodologies. The UMR uses higher baseline speeds and travel time unit cost values than most experts recommend, it exaggerates fuel savings and emission reductions, and ignores generated traffic impacts.
