The overall objective of this study is to assist transportation agencies in developing appropriate ITS strategies to improve traffic operations. This report summarizes the effort in applying innovative methods for ITS planning and ITS evaluation. First, the authors present a study using FHWA ITS Planning Process Version 2.1 to develop appropriate ITS strategies to accommodate local needs. A cas...

The objective of this research is to validate the Finite Element (FE) model of a Ford F800 Single Unit Truck (SUT). The FE Model of the SUT was developed at the FHWA/NHTSA National Crash Analysis Center (NCAC) at the George Washington University. The SUT model has been used by several transportation safety researchers to evaluate and improve roadside safety hardware. In this study, the characte...

The Federal Highway Administration (FHWA) mandates the use of affirmative action for minorityand women-owned firms by states in awarding federally funded road construction projects. In this paper, I document the variation of affirmative action across states over the history of the FHWA program, and I provide evidence regarding the effectiveness of affirmative action at increasing purchases from...

For several years the Federal Highway Administration (FHWA) Turner Fairbank Highway Research Center (TFHRC) has been conducting a research program on the effectiveness of roadway delineation for providing enhanced guidance to the driver negotiating curves on rural two-lane roads at night. The FHWA Highway Driving Simulator (HDS), located at the TFHRC, plays an important role in this research pr...

The structural analyses contained in this report were carried out under the direction of the National Transportation Safety Board Modeling Group with the participation of Professor Toshio Nakamura through an external contract with the State University of New York at Stony Brook. Added resources and expertise were acquired through a subcontract with Dassault Systèmes Simulia Corporation for assi...

The Intelligent Transportation System (ITS) relies heavily on data communications systems to link eld equipment such as traac sensors, changeable message signs and incident response vehicles with traac operations centers. This paper has two main purposes. The rst is to present a review of data communications concepts essential in the design of wireless modems for the ITS 220 MHz spectral alloca...

FOREWORD The goal of this research was to evaluate and estimate the effectiveness of improved curve delineation on rural two-lane undivided roads as one of the strategies in the Evaluation of Low-Cost Safety Improvements Pooled Fund Study (ELCSI-PFS), Phase II. This strategy is intended to reduce the frequency of crashes related to lack of driver awareness approaching curves as well as while na...

This report has been prepared by Mitretek systems for the Intelligent Transportation Systems (ITS) Joint Program Office Of the Federal Highway Administration (FHWA). The report documents the first phase of an investigation of how to " mainstream " , or integrate, ITS planning into general transportation planning at the state, regional and local levels. Specifically described are the processes b...
