Travel Behavior

This report describes the results of a PATH-funded study conducted by the Cal Poly Transportation Electronics Laboratory intended to assess advanced imaging technologies for potential application toroadway surveillance and detection. A major motivation for this study was the possibility of improvedvisibility under conditions of fog or dust using wavelengths longer than that of the visible spectral band. Technologies considered included ten types of infrared video cameras and one millimeter-wave still-frame imaging system. Evaluation criteria were structured to reflect the surveillance...

Complete streets movement is a national effort to return to traditional streets in our cities to enhance livability, safely, accommodate all modes of travel, provide travel choices, ease traffic congestion, and promote healthier communities. The California Department of Transportation (Caltrans) and several local agencies in the State have developed implementation plans for complete streets. In this project, we developed and tested improved strategies and analysis methodologies for complete streets, taking into consideration the emerging advances in technology on control devices and data...

In this paper, the authors present several throttle and brake control systems for automatic vehicle following. These control systems are designed and tested using a validated nonlinear vehicle model first and then actual vehicles. Each vehicle to be controlled is assumed to be equipped with sensors that, in addition to its own vehicle characteristics, provide measurements of the relative distance and relative speed between itself and the vehicle in front. Vehicle-to- vehicle communication required for the stability of the dynamics of a platoon of vehicles with desired constant intervehicle...

The purpose of this study is to investigate the reasons for an individual' s decision to ride rather than drive, and to draw any appropriate extensions to a future marketplace where automated vehicles may be an available mode choice. In the study, a focus group of existing vanpoolers is presented with the choice of driving alone or commuting with others after they had joined the vanpool. From the vanpoolers' stated choices, it is inferred whether a value may exist to future users of automated vehicles when they choose to travel in the automated mode, as opposed to driving themselves.
