This manual is intended for use as a tool in predicting the noise which will be generated by freely-flowing vehicle traffic along a highway of known characteristics. The manual presents two separate approaches to the prediction problem. The first approach utilizes a simple nomograph to provide first-approximation solutions to the traffic noise pred

Experience to Date with Impact Attenuators; Fatal Accidents on Completed Sections of the Interstate Highway System, 1968-70; U.S. Interstate Highway Interchange Milepost Designators—An Investigation of Efficient Coding Methods
Aerial photographs are useful in various studies of highway traffic behavior. From a timed sequence of aerial photographs of a fixed highway area, one can find for each vehicle crossing the area data on position, velocity, trajectory (i.e., entrancing, lane changing, and exiting) and type (i.e., car, truck, or bus). In this project, an interactive
