Intersection Diagnostic Review Module -will use an expert system approach to evaluate intersection design alternatives, identify geometric elements that may impact safety, and suggest countermeasures. The module will identify design elements not in compliance with policy and explain the policy violated. In response to this information, the user may either correct any deficiency or prepare a design exception. Traffic Analysis Module -will use traffic simulation models to estimate the operational effects of road designs under current and projected traffic flows. The Traffic Analysis Module will provide information on travel time, delay, interaction effects between vehicles, traffic conflicts and other surrogate safety measures.
Negotiations are underway with three additional commercial roadway design software developers.
