Utility Work Zone Temporary Traffic Control Plan Software
As a part of the Utility Work Zone Traffic Control Guidelines developed by Wayne State University under FHWA's Work Zone Safety Grants, this software program includes twenty-seven typical temporary traffic control plans (TTCPs) that were developed based upon site-specific work site factors that include the work location, type of roadway, the speed limit and traffic volume of the adjacent roadway. It allows users to select the TTCP most appropriate for a given utility work site.
Interactive Highway Safety Design Model (IHSDM)
Developed by FHWA's Safety Research and Development Program, IHSDM is a suite of software analysis tools for evaluating safety and operational effects of geometric design decisions on highways. It checks existing or proposed highway designs against relevant design policy values and provides estimates of a design’s expected safety and operational performance. The current version includes six evaluation modules: Crash Prediction, Policy Review, Design Consistency, Traffic Analysis, Driver/Vehicle and Intersection Review.
Developed by FHWA, QuickZone is a computer-based traffic analysis tool that compares the traffic impacts for work zone mitigation strategies and estimates the costs, traffic delays, and potential backups associated with these impacts.
Developed by Texas A&M Transportation Institute in cooperation with the Texas Department of Transportation, QUEWZ-98 is a microcomputer analysis tool for planning and scheduling use in freeway work zone lane closures. It analyzes traffic conditions on a freeway segment with and without a lane closure in place and provides estimates of the additional road user costs and of the queuing resulting from a work zone lane closure. The road user costs calculated include travel time, vehicle operating costs, and excess emissions.
FREWAY (Freeway Delay Calculation Program)
Developed by Center for Microcomputers in Transportation at University of Florida, FREWAY is a computer program that estimates the annual impacts of urban freeway congestion on individual freeway sections in congested vehicle miles of travel, motorist delay, wasted fuel and user costs. Estimates are made for recurring and non-recurring congestion.
Developed by Texas A&M Transportation Institute, MicroBENCOST is a computer program for analyzing benefits and costs of a wide range of highway improvements. It can also allocate corridor traffic and calculate forecasted traffic volumes. The program is capable of analyzing seven categories of projects: added-capacity, bypass, intersection/interchange, pavement rehabilitation, bridge, safety and highway-railroad grade crossing. It can be used to analyze work zones and incidents in conjunction with those project types.
