TRB's second Strategic Highway Research Program (SHRP 2) Report S2-S03-RW-1: Roadway Measurement System Evaluation 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.
This report is only available in electronic format.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 415: Design Fires in Road Tunnels information on the state of the practice of design fires in road tunnels, focusing on tunnel fire dynamics and the means of fire management for design guidance.
Note: On September 20, 2011, the following errata was released related to NCHRP Synthesis 415. The electronic version of the publicaiton was changed to reflect the corrections.
On pages 106 and 107, an incorrect reference was cited. In the final paragraph on page 106, the last sentence should read: One study[more]
TRB's National Cooperative Highway Research Program (NCHRP) Report 695: Guide for Implementing a Geospatially Enabled Enterprise-wide Information Management System for Transportation Agency Real Estate Offices provides guidance for right-of-way offices in implementing a geospatially enabled enterprise-wide information management system and includes a logical model to assist with this implementation.
NCHRP Reort 695 presents the guide for implementing the logical model; a CD-ROM, included with the print version of the report, presents the logical model and a guide for its use. The
TRB's National Cooperative Highway Research Program (NCHRP) Report 699: Guidelines for the Use of Pavement Warranties on Highway Construction Projects is designed to help guide state departments of transportation (DOTs) in establishing pavement warranty programs.
The guide identifies programmatic and project-level decision criteria that DOTs should consider when implementing and sustaining a program. The guide presents strategies to mitigate project-specific risks and also includes model warranty specification provisions.
The guide also includes a decision tool to help id
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 417: Geometric Design Practices for Resurfacing, Restoration, and Rehabilitation documents the current state-of-the-practice related to nonfreeway resurfacing, restoration, and rehabilitation projects.
Appendix G, Summary of Good Practices: Incorporating Safety into Resurfacing and Restoration Projects, to NCHRP Synthesis 417 is only available as part of the electronic version of the report.
TRB's National Cooperative Highway Research Program (NCHRP) Report 688: Determining Highway Maintenance Costs presents a process for determining a highway agency's full costs associated with performing highway maintenance.
The process described in the report can be applied to any specific maintenance activity and is designed to help ensure that the resulting full cost incorporates a fair share of both maintenance program and enterprise support costs.
The report also documents the application of the full-cost determination process for a number of highway agencies and diffe
TRB's National Cooperative Highway Research Program (NCHRP) Report 689: Costs of Alternative Revenue-Generation Systems presents a framework for analysis of the direct costs incurred in generating the revenues that support federal-aid and state highway construction, operations, and maintenance and uses that framework to estimate unit costs for fuel taxes, tolling, vehicle-miles of travel fees, and cordon pricing schemes.
TRB's Hazardous Materials Cooperative Research Program (HMCRP) Report 4: Emerging Technologies Applicable to Hazardous Materials Transportation Safety and Security explores near-term (less than 5 years) and longer-term (5â€"10 years) technologies that are candidates for enhancing the safety and security of hazardous materials transportation for use by shippers, carriers, emergency responders, or government regulatory and enforcement agencies.
The report examines emerging generic technologies that hold promise of being introduced during these near- and longer-term spans. It also high
TRB's National Cooperative Highway Research Program (NCHRP) Report 673: A Manual for Design of Hot-Mix Asphalt with Commentary incorporates the many advances in materials characterization and hot-mix asphalt (HMA) mix design technology developed since the conclusion of the Strategic Highway Research Program (SHRP).
The final report on the project that developed NCHRP Report 673 and Appendixes C through F to NCHRP Report 673 were published as NCHRP Web-Only Document 159. The titles of the appendixes are as follo
TRB's National Cooperative Highway Research Program (NCHRP) Report 683: Protocols for Collecting and Using Traffic Data in Bridge Design explores a set of protocols and methodologies for using available recent truck traffic data to develop and calibrate vehicular loads for superstructure design, fatigue design, deck design, and design for overload permits.
The protocols are geared to address the collection, processing, and use of national weigh-in-motion (WIM) data. The report also gives practical examples of implementing these protocols with recent national WIM data drawn from stat
