Software & Analysis Tools

Interactive Highway Safety Design Model (IHSDM)
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.

QuickZone
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.

QUEWZ-98
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)
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.

MicroBENCOST
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.
