TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2395 consists of 15 papers that examine the breakdown maturity phenomenon at Wisconsin freeway bottlenecks; dynamic modeling of Vissim’s critical gap parameter at unsignalized intersections; the freeway facilities method in the Highway Capacity Manual; sensitivity testing of multimodal level of service in the Highway Capacity Manual; development of an oversaturated speed–flow model; assessment of design hours for freeways; operational effectiveness of passing zones; and revised version of the automobile level-of-service methodology for urban streets. This issue of the TRR also explores multistep-approach lane changes at expressway merge bottlenecks in Shanghai, China; lane-based breakdown identification; volume-to-capacity estimation of signalized road networks; examination of freeways in California; quantifying measurement error in arterial travel times; estimation of incident propensity for reliability analysis in the Highway Capacity Manual; and a capacity analysis procedure for nonstandard two-way stop-controlled intersections.
