Digital-computer-controlled Traffic Signal System for a Small City


Book Description

Research was conducted to apply state-of-the-art computer technology to traffic signal control, with emphasis being placed on applications for the small or medium-size city. The most comprehensive analysis of control logic to date coupled with a synthesis of the hardware required for a real-time closed-loop digital-computer-controlled traffic signal system is presented. Utilizing the city of White Plains, N.Y. as a model, a typical computer signal system is specified, equipment is selected, and costs are estimated for its 116 signalized intersections.

Measurement of Pavement Thickness by Rapid and Nondestructive Methods


Book Description

The feasibility is investigated of various acoustic (sonic), nuclear, and electrical techniques for nondestructive measurement of Portland cement and bituminous concrete pavement thickness both during and after construction. Recommendations are made for equipment development and field testing of three specific methods that could potentially result in such measurements with the desired degree of speed and accuracy.
