Traffic signal systems are addressed in a number of papers covering topics that include decision support systems for modification of signal control in an urban signal system, the optimal design of traffic detector layout and controller timing in terms of safety and operations, development of an enhanced delay estimation model, and development of different computer programs for network signal timing and optimization. Traffic control devices and visibility are the focus of four papers. The reader will find papers related to the concepts of a separate category of traffic signs to control traffic in emergency situations, the adequacy of current federal Interstate vision standards for commercial motor vehicle operators, the validity of the current specifications for entrance angles for retroreflective traffic signs, and the development of a computer program to determine the actual angles at which traffic signs are seen by drivers.
