Preface

• The incorporation of IT at all levels of the transportation system can greatly enhance productivity

• Examples from Los Angeles illustrate opportunities to improve freeway system management and assist travelers

• Automation offers dramatic, long-term, opportunities

• Exploiting these requires a strong partnership between state, industry, and academia

8

Improving performance today: the PeMS system• PeMS collects and stores data

captured by loop detectors in the State’s freeways in a central database. PeMS also obtains and stores CHP-published incident data

• The central database is currently located on the UC Berkeley campus, but it can be accessed from anywhere via the Internet

• Data are sent from the TMCs to UC Berkeley over the Caltrans wide area network (WAN)

9

Improving performance tomorrow: Automated Highway Systems

Potential for doubling or tripling highway capacity per laneAncillary benefits follow in safety, driver comfort/convenience, and energy/emissionsInitial applications are likely to be on heavy vehicles (buses, trucks), but the BIG benefits come with light-duty vehiclesAutomated cars can capture public imaginationWe’re working on deployment staging scenarios
