San Francisco Bay Area's Experience Developing Transportation Control Measures for Air Quality Plans
The San Francisco Bay Area has included Transportation Control Measures (TCMs) in air quality planning efforts since the early 1970s. Growing concern for traffic congestion has enhanced...
Effectiveness of Implemented HOV Lane System
Individual carpool lanes have proven their worth on a case by case basis. Now, in California and across the country, systems of HOV lanes are being planned for urban areas dealing with...
Travel Markets: An Approach to TCM Effectiveness Evaluation
This discussion paper describes a new approach to TCM evaluation using a travel market concept to classify trip types based on expected elasticities to various TCMs. Conventional trip...
Evaluating the Effectiveness of Transportation Control Measures for San Luis Obispo County, California
The San Luis Obispo Air Pollution Control District has developed simple techniques to estimate emission reductions from various Transportation Control Measures. Accurate emission estimates...
The Effectiveness of Telecommuting as a Transportation Control Measure
This paper examines the potential of telecommuting as a strategy for managing travel demand. In particular, the paper focuses on the travel and air quality implications of telecommuting....
The Monitoring of Water Conservation Behavior and Attitudes in Southern California
Seldom are the effects of public information programs monitored and analyzed in a sound, systematic manner. Information on the impact of investments in public information programs is essential:...
A Probabilistic Regional Damage Estimation Model for Earthquake Occurrences
In this paper we present a model for estimating regional earthquake damage. The model utilizes the relational data base management system ORACLE and the geographic information system ARC/INFO...
Development of a Limit-State Seismic Code for Bridges
The catastrophic collapse of the Cypress Street Viaduct during the Loma Prieta earthquake of October 17, 1989 and the loss of spans in both the Struve Slough Bridge and the San Francisco-Oakland...
Response of Suspension and Deck Arch Bridges to Spatially Varying Ground Motion
Recent awareness of the spatial variation of earthquake ground motion has caused concern about the safety of large engineered structures under seismic excitation. The effects of spatially...
Degradation of Ground Water by Tetrachloroethylene
Ground water from many municipal water wells in California has been degraded by tetrachloroethylene (PCE) at concentrations above the drinking water standard. Investigations conducted...
