SPRINTER Rail: Grade Crossing/Traffic Signal Optimization Study

2009

The second phase of this project further investigates impacts to local traffic operations at intersections adjacent to signal preemption by SPRINTER commuter trains and comes up with countermeasures that not only minimize such impacts but also take into account the traffic signal coordination. An extended traffic signal optimization model has been developed to minimize overall traffic delays and the weighted width of “green band” along several coordinated traffic signals around the grade crossings. Based on the train’s movement detection at grade crossings and the waiting queue estimation...

This project is to assist the Capitol Corridor Joint Power Authority (CCIPA) and the California Department of Transportation (Caltrans) assemble a decision framework for selecting wireless Internet access on behalf of customers riding the three California State sponsored Intercity Rail Services. To accomplish this objective, we researched the state of worldwide deployment of service based on the wireless technologies, such as wireless fidelity (WiFi) and Worldwide Interoperability for Microwave Access(WiMAX), conducted a survey of the WiFi service at San Francisco Airport, and examined the...

Urban Densities and Transit: A Multi-Dimensional Perspective

Cervero, Robert
Guerra, Erick
2011

This paper investigates the relationship between transit and urban densities in the United States. An analysis of light rail systems finds that a residential density of about 30 people per gross acre near stations is needed to in order to make them among the top 25 percent of rail transit investments in terms of cost effectiveness; for heavy rail systems, the density is 45 people per gross acre. Increasing density around stations would greatly increase ridership, particularly when jobs are located within one-quarter mile of the stations and housing is located within one-half mile....

Developing Operating Rules and Simulating Performance for One-dedicated-lane Bus Rapid Transit/Light Rail System

2010

Caltrans has recently funded a project, through the Mineta Transportation Institute (MTI) at San Jose State University, about geometric and performance feasibility of using virtually only one dedicated but dynamically reversible lane to provide two-way Bus Rapid Transit (BRT) or light-rail services at the same or similar service levels as those achievable with two dedicated lanes, along the median of a busy commute corridor with at-grade crossings and regular provision of left-turn lanes. This project extended that deterministic performance study in four complementary directions. We (i)...

San Joaquin Rail Corridor Crossing Survey

Greenhouse, Daniel
Christianson, Kent
Johnston, Scott
Kim, Zu
2008

In this project we have accomplished three goals. First, we have merged two existing, complementary databases in an effort to produce a single database that lists all the railroad crossings, and their known properties, in the San Joaquin Rail Corridor (SJRC). Second, we have demonstrated the practicality of using video data gathered from an existing Locomotive Video Data Acquistion System (LVDAS) to search for crossing violations in order to populate a database of crossing violations, which we term “near-misses”. By this means, crossings that are particularly susceptible to violations,...

Transportation Periodicals and Newsletters Currently Received at the Institute of Transportation Studies Library, University of California at Berkeley

Hernandez, Paul A.
2000

This publication is intended to serve as a convenient reference to selected transportation periodicals and newsletters currently (2000) received by UC Berkeley's Harmer E. Davis Transportation Li-brary. This latest version of Transportation Periodicals and Newsletters represents a thourough revision of earlier editions (1989, 1993, and 1995) published under the same (or similar) title. The subject content of this listing reflects the subject strengths of the H.E. Davis Transportation Library: highways and traffic, air transportation, railroads, and urban transit. Water and pipeline modes...

The Full Cost of Intercity Transportation - A Comparison of High Speed Rail, Air And Highway Transportation in California

Levinson, David
Gillen, David
Kanafani, Adib
Mathieu, Jean-michel
1996

The Full Cost of Intercity Transportation Page ES-1 This study evaluates the full cost of three modes of intercity transportation: air, highway, and high speed rail. The evaluation is done within the context of the California Corridor, connecting the Los Angeles Basin and the San Francisco Bay Area. The purpose of evaluating full cost is to compare the economic implications of investment in, or expansion of, any of these three modes. The scope of the analysis is full transportation cost. Full transportation costs includes external, or social cost, in addition to the internal costs of...
