A feature article in the September-October 2009 issue of the TR News explores differences in the travel behavior of minority populations that could have wide-reaching implications for short- and long-term policy development, planning, and travel demand forecasting.   

TRB’s National Cooperative Highway Research Program (NCHRP) Report 526: Snow and Ice Control: Guidelines for Materials and Methods provides guidance for selecting roadway snow and ice control strategies, and tactics for a wide range of winter maintenance operating conditions. This guidance applie

The Report to Congress summarizes the key results for the Value Pricing Pilot Program (VPPP) since 1991. Projects and studies conducted as part of the VPPP have provided many valuable lessons, but six key findings demonstrate the significant progress made in the past few years toward successful d

This primer is intended to raise awareness among staff at MPOs and their partner agencies about the potential role of congestion pricing in supporting regional goals as well as the most effective approaches for advancing congestion pricing strategies in a region. It draws upon lessons learned from p

Over the last half century, the public’s increasing demand for fast, efficient, and convenient means of travel has resulted in greater use and dependency on existing transportation infrastructure, including freeways and their associated ramps, to meet their personal and/or business needs. This incre

This Informational Brief highlights ramp metering as a proven, effective strategy for reducing congestion and improving safety. The Brief covers at a high-level the benefits of ramp metering, status of ramp metering deployment in the U.S., keys for successful deployment and operation, and resourc

This primer poses ramp metering as a potential tool to address commonly occurring congestion and safety issues. Despite initial opposition and skepticism from various stakeholders, ramp metering has been deployed, sustained, and even expanded in many regions. This primer incorporates recent resea

OR 217, a 7.5-­‐mile limited-­‐access expressway in Portland, Oregon was the subject of several studies that recommended capacity and interchange improvements costing nearly $1 billion. Because of limited funding, the Oregon Department of Transportation (ODOT) and the DKS Associates Team evaluate

The management of highway traffic incidents that occur on Oregon state highways requires the response of multiple state and local government organizations. Emergency incidents can range from a vehicle crash to a landslide that has closed a highway. Interagency communication is needed to insure th
