Research Highlights

Long term evaluation of individualized marketing programs for travel demand management

Jennifer Dill
Cynthia Mohr
With increasing concerns over traffic congestion, fossil fuel use, air pollution, and livability, coupled with severe constraints on funding for new transportation infrastructure, cities and regions are increasingly looking to a wider range of options to address transportation problems. Transportation demand management (TDM) is one of those options used over the past 30+ years with varying success. Historically in the U.S., programs have focused on commute trips and employers or broad-based a... Read More

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Miguel Figliozzi
Christopher Monsere
This research proposes a novel approach to study the microscopic, intersection-level interactions of two advanced control technologies: SCATS adaptive traffic signal control and transit signal priority (TSP). These interactions will be studied using Powell Blvd (PB), which is a fully instrumented urban corridor in Portland, OR. The corridor is severely congested during peak periods and has low levels of service (LOS) for transit, and motor vehicles. and pedestrians. This research will mode... Read More
