Improving Traffic Incident Scene Management, was designed to establish the foundation for and promote certification of responders to achieve the three objectives of the traffic incident management (TIM) national unified goal (NUG). The intent is to motivate responders from different stakeholder g

provides guidance to transportation agencies at the state, regional, metropolitan, and local levels on how best to collaborate with private-sector freight stakeholders in planning and developing future highway capacity. As both the C15 project and the accompanying C20 project (improving freight d

The purpose of this synthesis report is to provide guidance to practitioners for short-term deployment planning. The authors interviewed agencies to identify deployment approaches and classified those approaches based on decisions made regarding where, when, and what TSM&O strategies were dep

This report documents the evaluation of automated/mobile data-collection services to provide data on roadway features and characteristics considered important for safety analysis, especially analysis of data from the SHRP 2 Naturalistic Driving Study (NDS). To obtain these roadway data, SHRP 2 se

This report reviews domestic and international literature describing current research and state of the practice in using travel time reliability in transportation planning; summarizes case studies from agencies working to incorporate reliability into their transportation planning processes. Furth

This guidebook provides step-by-step procedures for designing and conducting empirically based (i.e., observational) before-and-after studies for operations strategies. While the focus is on operational strategies, the same procedures may be applied to any highway congestion mitigation strategies

Transportation systems management and operations (TSM&O) strategies can improve travel time reliability, which yields both safety and economic benefits and improves road-user experience. To date, only a few transportation agencies have TSM&O programs to address travel time reliability, bu

Adding transportation capacity improves safety, accessibility, and the economic health of a region but often comes with an economic, social, or environmental price. The public is aware of the price and must be convinced that new capacity is really needed before they will suppor

The research project that produced this report focused on answering the following related questions:

This guide, which focuses on showing how to use BPMN for mapping traffic operations business processes, is intended to help transportation agencies move forward in addressing nonrecurring traffic congestion and delivering more reliable travel times on their highway networks. The guide explores va
