Major problem in operating transportation system is traffic overloading demands at peak periods; expressway Surveillance Project was formed to improve efficiency of highway system through application of electronic automation and traffic engineering to problem of traffic congestion; by providing means for quick response in case of accidents and fast removal of hindrances, volume capability of freeways was effectively increased during peak periods; use of ramp metering controls achieved reduction in delay, safer merging characteristics, and reduced freeway accidents.
