The major goal of travel behavior research is to understand and model the processes by which people make decisions regarding activities and travel. These decisions, including whether, when, where, and with whom to participate in particular activities, and the choice of mode and route, are...

Travel demand models focus on explaining how much individuals actually travel but offer no insight into how much individuals think they travel. The authors propose that the latter is an important determinant of traveler behavior, and that actual mobility is refracted through a variety of filters...

In this article, we describe the development of atransit trip planner(TTP) for mobile devicescalled Transitr, and evaluate its performance. The system predicts the shortest paths betweenany two points in the transit network using real-time information provided by a third party busarrival...

The City of Los Angeles and Caltrans would like a simulation testbed for testing alternate traffic management strategies in the Santa Monica corridor. This study assesses the data available for such a simulation and describes data needs, potential sources, and data preparation required. It...

This paper presents the results of a qualitative survey of commercial owners, managers, and occupants in the City of Berkeley who have invested in on-site bicycle facilities such as secure parking, showers, changing rooms, and clothing lockers, what we are calling “bicycle-oriented...

In this paper, the authors design an adaptive control scheme for electronic throttle that achieves good tracking of arbitrary constant speed commands in the presence of unknown disturbances. The design is based on a simplified linear vehicle model which is derived from a validated nonlinear one....

We consider a Generalized, Multiple Depot Hamiltonian Path Problem (GMDHPP) and show that it has an algorithm with an approximation ratio of 3/2 if the costs are symmetric and satisfy the triangle inequality. This improves on the 2-approximation algorithm already available for the same.

The TravInfo project aims to develop a multi-modal traveler information system for the San Francisco Bay Area, developing a partnership between the public and private sectors. This report presents the results of the first wave of institutional interviews, as part of the TravInfo evaluation.

OBJECTIVE: In order to demonstrate the results of all available studies on cost-effectiveness and traffic safety, and report them in a comparable format, we conducted a comprehensive review of the literature on the subject. Knowledge of cost-effective (CE) traffic safety programs that result in...
