In an attempt to improve traffic flows on urban freeways, the California Department of Transportation (Caltrans) has recently implemented a demonstration project on a Southern California freeway to test the traffic operational features of a special commuter lane. The lane is being provided by allowing high-occupancy vehicles to drive on the median shoulder during peak commuter hours when the freeway is congested. In developing the project, Caltrans took into consideration several points relative to the operation of high-occupancy-vehicle lanes, the need for added capacity, and the conversion of shoulders into traffic lanes, which are discussed. Several factors are being reviewed in evaluating the operation of the project: accident experience, violation rates, operations associated with weaving and merging movements, travel times, congestion relief, and public acceptance. Results are presented and discussed.
