I-880 Corridor Management Plan Demonstration - Final Report Now Available

In 2004, under sponsorship from the California Department of Transportation, the California Center for Innovative Transportation (CCIT) at the University of California, Berkeley began the process to evaluate the performance of a heavily congested major urban transportation corridor in the San Francisco Bay Area and to model and assess the benefits of a variety of transportation investments upon the corridor. Systems Metrics Group (SMG), a subcontractor to CCIT and responsible party to conduct the overall evaluation, modeling and investment assessment has returned with a comprehensive and scientifically justifiable assessment of Interstate 880, the selected corridor with boundaries that include the SR-237 Interchange in Fremont to the Grand Avenue Interchange in Oakland. Through extensive performance monitoring, SMG was able to conduct and document a comprehensive performance assessment of the corridor and through the use of sophisticated microscopic traffic simulation modeling tools and techniques, to evaluate the validity of a variety of investment scenarios.

While not intended to replace other studies, this analysis represents the first attempt by the California Department of Transportation to address existing travel conditions and mobility challenges though the integration of operational analyses, traditional planning management strategies, and capital improvements all based upon a strong and scientific assessment of existing conditions and potential scenarios. In summary, results of this study produced a return-on-investment ranking for a variety of improvement opportunities for the Interstate 880 corridor, primarily located in bottle-neck related problem areas. In addition, the study identified advanced ramp metering as the highest performing investment included in the study and proposes, among other recommendations, that Caltrans and its partners focus on properly implemented advanced ramp metering systems along the Interstate 880 corridor.

Privately-Provided Commuter Bus Services: Role in the San Francisco Bay Area Regional Transportation Network - White Paper Available

High gas prices, the lengthening of commutes and the ability to use travel time productively has created demand for commuter bus services. This CCIT White Paper focuses on transit initiatives provided by private companies to meet commute travel demand and aims to clarify their role in the regional transportation system.

Commuters are drawn to privately-provided commuter bus service, particularly in the San Francisco Bay Area, as it reflects their preferences and commute routes. The commuter buses operate during peak hours and offer customer-oriented routes with limited stops, wireless internet access and coach amenities to suburban employment destinations. The success of privately-provided commuter bus services have reduced the number of commuters driving alone over long distances, resulting in fewer cars on local streets and regional highways, and reduced greenhouse gas emissions.

The proliferation of privately-provided commuter programs in the Bay Area will require formal recognition by public agencies. Federal, state and local public agencies can provide support and guidelines to enable more privately-provided commuter bus services to be offered in a way that is complementary to public transit and meet the needs of the commuter population.
