This document is a technical summary of the Federal Highway Administration (FHWA) report, "Box Beam Bridges: Testing of Conventional Grout and Ultra-High Performance Concrete Connection Details" (FHWA-HRT-17-093).
The Federal Highway Administration (FHWA) established the Development of Crash Modification Factors (DCMF) program to address highway safety research needs for evaluating new and innovative safety strategies (improvements) by developing reliable quantitative estimates of their effectiveness in reducing crashes. The ultimate goal of the DCMF program

Innovator, published by the FHWA Center for Accelerating Innovation, advances implementation of innovative technologies and processes in the highway industry. Its audience is transportation professionals in highway agencies, trade and research groups, academia and the private sector, and the driving public.
Emerging datasets such as mobile phone and GPS data have now become a promising data source for many transportation planning applications, including origin-destination (OD) analyses, which serve as the basis for transportation investment and policy decisions. Generated from an entirely different process from the traditional household travel surveys

Based on current practices, traffic simulation models are calibrated and validated using macroscopic measures such as 15-minute averages of traffic counts or average point-to-point travel times. For an emerging number of applications, including connected vehicles, the realism of simulated driver dynamics at the second-by-second or subsecond traject

This report describes the process of developing, analyzing, and displaying results of a scenario forecasting process using travel demand models. A Travel Time Index (TTI) is the ratio of travel time without congestion (called free flow) and congested travel times, usually during a peak period. With this common measure, planners can compare and cont
