After a 5-year study of transportation planning in the San Francisco Bay Area, we have concluded that the contentiousness we observed in the process was due in great part to differences in participants’ styles of planning and not solely to disagreements over desired outcomes. Each style...

Modern panel surveys frequently suffer from high and likely non-ignorable attrition, and transportation surveys suffer from poor travel time estimates. This paper examines new methods for adjusting forecasts and model estimates to account for these problems. The methods we describe are...

Despite its application in many fields, map matching in studies of travel/transport geography is unique in two aspects: 1) The correct road links traversed by the traveler need to be unambiguously identified; 2) All the identified links should form a meaningful travel route. This paper discusses...

Moving the marketplace to clean and efficient vehicles is proving a complex, difficult, and long-term project. The first step, the development and commercialization of several technologies including electric, hybrid-electric, and alternative fuel vehicles is well underway. Now we must take the...

Transportation system produces a large percentage of local pollutants including hydrocarbons (HC), carbon monoxide (CO), carbon dioxide from switching to alternative fuels, one measure would be to apply information and communication technologies to help us drive more smoothly so as to decrease...

In this paper, we implement an estimation procedure for a particular mathematical programming activity-based model in order to estimate the relative importance of factors associated with spatial and temporal interrelationships among the out-of-home activities that motivate a household’s...

This article reviews empirical studies of how employer-paid parking affects employees’ travel choices. A strong effect is found: parking subsidies greatly increase solo driving. When employers reduce or remove parking subsidies, a significant number of solo drivers shift to earpools...

One-half mile has become the accepted distance for gauging a transit station’s catchment area in the U.S. It is the de facto standard for planning TODs (transit oriented developments) in America. Planners and researchers use transit catchment areas not only to make predictions about...

The city evacuation problem is analyzed physically at the freeway and network levels. On a freeway, a macroscopic approach is used to identify the critical bottlenecks that determine the system’s evacuation capacity. Knowledge of these bottlenecks leads to the development of an input...
