ITS at Trimet: Improving Service and Saving Money

View slides

The video begins at 6:57.

The Tri-County Metropolitan Transportation District of Oregon (TriMet), the transit provider for urban Clackamas, Multnomah, and Washington Counties, has been a leader in applying ITS technologies to its operations since the mid-1990s. The use of ITS technology has enhanced service for its customers while providing significant operational efficiencies.

In this presentation, analyst David Crout will describe many of TriMet's ITS projects, including the automatic vehicle location (AVL) system, computer-aided dispatch (CAD), real-time customer information, transit signal priority, and automatic stop announcements, and show how they have resulted in improved service and cost savings for the agency.

Using Archived ITS Data to Measure the Operational Benefits of a System-Wide Adaptive Ramp Metering System (SWARM)

The video begins at 1:48.

A System-Wide Adaptive Ramp Metering (SWARM) system is being implemented in the Portland metropolitan area and should be operational on all corridors by April 2006. This study entails a before and after evaluation of the operational benefits of the new SWARM system using the existing data, surveillance and communications infrastructure. In particular, the study will quantify system-wide benefits in terms of savings in delay, emissions and fuel consumption and safety improvements on and off the freeway due to the implementation of the ramp metering system. This will aid in the optimal deployment of current SWARM system and will be transferable to other regions as their systems come on line in the future.
