This paper describes the experimental analysis techniques and modelling efforts applied to sequential pre-trip route choice behavior data under the influence of an Advanced Traveler Information System (ATIS). This effort is the first step in a process to develop a basic understanding of the...

This report documents findings from a series of studies investigating how Intelligent Transportation Systems (ITS) could be used to improve the integration of commercial vehicle operations (CVO) with governmental services and regulations within intermodal transportation management centers. After...

This paper presents a simple prototype to demonstrate the key functions of PLANiTS (Planning and Analysis for Integration for Intelligent Transportation Systems). The prototype has a planning vector that allows users to enter and edit transportation actions, performance measures and...

This report focuses on traffic congestion under current road conditions with the objective of developing a quantitative understanding of their costs. The work is intended to provide a foundation upon which to build later estimates of the benefits that could be attributable to the use of...

The primary objective of this paper is to review the appropriate use of ratio variables in the study of pedestrian injury exposure. We provide a discussion that rejects the assumption that the relationship between a random variable (e.g., a population X) and a ratio (e.g., injury or disease per...

The Mobile TMC and various field elements were developed for Caltrans Division of Research and Innovation (DRI) between 1994 and 2002. These systems were all designed to operate independent of one another to provide on-site traffic data collection, video surveillance, and traffic management...

The goal of this effort is to devise and analyze an integrated Physical/ Link-Access Layer Model of packet Radio Architectures, with application to the PATH/IVHS (Intelligent Vehicle Highway Systems) communication sub- system design between vehicles and infrastructure, as well as between...

The focus of this project is to study alternative system architectures and ITS technologies that can improve the efficiency of personalized public transit and demand responsive systems such as paratransit. This report reviews available and emerging ITS technologies that have been deployed or are...
