This user manual provides guidance for the use of the Enhanced Interchange Safety Analysis Tool (ISATe). This tool can be used to evaluate freeway and interchange safety. The algorithms and equations used in ISATe are implemented in a Microsoft ® Excel ® workbook as software (using the Visual-Basicfor-Applications programming language). The user manual consists of three chapters. The […]
This guide provides examples of opportunities for integrating the AASHTO Highway Safety Manual into the project development process. This includes integrating methods from the Highway Safety Manual into planning, alternatives development and analysis, design, operations, and maintenance. The guide provides a description of each of these steps in the project development process, and then provides a discussion of the […]
Guangqing Chi, Timothy E. McClure, & David B. Brown Objective: The price of gasoline has been found to be negatively associated with traffic crashes in a limited number of studies. However, most of the studies have focused either on fatal crashes only or on all crashes but measured over a very short time period. In […]
As the weather warms and schools break for spring and summer, traffic swells along Alabama’s most popular highways, often resulting in more crashes, injuries, and fatalities.

The resulting information can then be used to provide guidelines to […]
A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road. The new technology […]
