The Innovative Corridors Initiative (ICI) is a multi-year project designed to encouarge the early deployment of innovative technologies for Intelligent Transportation Systems (ITS) in California. ITS technologies are defined through a broad array of information and vehicle control technologies that are designed to improve traffic and transit management including safety, user choice, congestion, and incident response.

Policy Considerations for Carsharing & Station Cars: Monitoring Growth, Trends, and Overall Impacts

Since the late-1990s, over 25 U.S. shared-use vehicle programs – including carsharing and station cars – have been launched. Given their presumed social and environmental benefits, the majority of these programs received some governmental support – primarily in the form of startup grants and subsidized parking. As of July 2003, there were a total of 15 shared-use vehicle programs, including 11 carsharing organizations, two carsharing research pilots, and two station car programs, Over the last five years, U.S. carsharing membership has experienced exponential growth.

Integrated Hydrogen and Intelligent Transportation Systems Evaluation for the California Department of Transportation

2005

This “Integrated Hydrogen/Intelligent Transportation Systems Evaluation for the California Department of Transportation” project was conceived to investigate hydrogen activities in the State and around the U.S. that might impact the California Department of Transportation’s (Caltrans) operations. The project is intended to review these activities and to suggest potential interesting applications of combined hydrogen and intelligent transportation system (ITS) technologies.

Travel Effects of A Suburban Commuter Carsharing Service: CarLink Case Study

2005

Since 1998, carsharing programs (or short-term auto rentals) in the U.S. have experienced exponential membership growth. As of July 2003, 15 carsharing organizations collectively claimed 25,727 members and 784 vehicles. Given this growing demand, decision makers and transit operators are increasingly interested in understanding the potential for carsharing services to increase transit use, reduce auto ownership, and lower vehicle miles traveled. However, to date, there is only limited evidence of potential program effects in the U.S. and Europe.

Enhanced Transit Strategies: Bus Lanes with Intermittent Priority and ITS Technology Architectures for TOD enhancements

2006

Due to increases in congestion, transportation costs, and associated environmental impacts, a variety of new enhanced transit strategies are being investigated worldwide. The transit-oriented development (TOD) concept is a key area where several enhanced transit strategies can be implemented. TODs integrate transit, residential, retail and/or commercial entities into a compact, pedestrian-friendly community, thereby reducing private car usage and increasing transit use.

Assessing Early Market Potential for Carsharing in China: A Case Study of Beijing

Susan Shaheen, PhD and Elliot Martin
2006

Carsharing is the short-term use of a shared vehicle fleet by authorized members. Since 1998, U.S. carsharing services have experienced exponential growth. At present, there are 13 carsharing organizations. Over the past three years, electronic and wireless technologies have been developed that can facilitate carsharing system management in the U.S., improve customer services, and reduce program costs. This paper examines the U.S.

Carsharing in North America: Market Growth, Current Developments, and Future Potential

Susan Shaheen, PhD, Adam Cohen, and J. Darius Roberts
2006

Carsharing provides members access to a fleet of autos for short-term use throughout the day, reducing the need for one or more personal vehicles. Over ten years ago, carsharing operators began to appear in North America. Since 1994, a total of 40 programs have been deployed–28 are operating in 36 urban areas and 12 are now defunct. Another four are planned to launch in the next year. This paper examines carsharing growth potential in North America, based on a survey of 26 existing organizations conducted from April to July 2005.

Innovative Corridors Initiative: Call for Submission Process and Evaluation

2007

The Innovative Corridors Initiative represents an innovative business model for public agencies to partner with private industry to improve transportation system management and provide real time information to users. The Call for Submissions (CFS) issued by Caltrans, MTC, LA MTA, ITS America, and CCIToffered private industry access to public rights-of-way and data. However, no funds were offered as part of the CFS, meaning the companies that submitted a proposal and participated needed to have the capacity to self-fund their projects.

Commercial Vehicle Parking in California: Exploratory Evaluation of the Problem and Possible Technology-Based Solutions

2007

The United States is experiencing dramatic growth in commercial vehicle truck travel on our nation’s roadway system as well as critical shortages in truck parking. California ranks first in the nation’s overall (private and public) commercial vehicle parking shortage. Recent estimates of the demand for truck parking in California indicate that demand exceeds capacity at all public rest areas; this is the case at 88 percent of private truck stops on the 34 corridors in California with the highest truck travel volumes.

Smart Parking Pilot on the Coaster Commuter Rail Line in San Diego, California

2007

Increasingly, public transit authorities are harnessing advances in sensor, payment, and enforcement technologies to operate parking facilities more efficiently. In the short term, these innovations promise to enhance customer parking experiences, increase the effective supply of existing parking with minimal investment, and increase ridership and overall revenue. Over the longer term, these systems could further expand ridership by generating revenue to add parking capacity and improve access.
