Improved safety and efficiency of operations on freeways were the goals of research reported in the six papers in this Record. This research included: a study of automatic means of detecting stoppage waves; development of a computer program capable of determining desired fixed-time metering rates for a group of freeway onramps; prediction of the presence of acceptable gaps into which ramp vehicles can be merged; examination of fatal accident experience by highway system types and fatal Interstate System accidents as related to Interstate travel data; improvement of fixed-time ramp-metering control strategies; and study of a system to move investigation of freeway accidents to concealed off-freeway sites.
