| Abstract | Different methods for calculating the capacity of a traffic facility have given different solutions to the same problem. At the same time, it has been clearly shown that the actual capacity is higher than that indicated by calculation methods. The Swedish Road Administration has therefore completed a research and development project that produced a new capacity manual, which should improve old methods, produce new ones for types of facilities and efficiency factors not previously treated, and achieve uniform application of the methods in Sweden. The new manual treats three categories of traffic: motor vehicle traffic, bicycle traffic and pedestrians. The main efficiency factors are capacity, queue length delay, and proportion of stopped vehicles. Explanatory models based on the quene theory of motorist behavior have been chosen to limit the empirical evidence to parameters such as critical time headway. The main new types of facilities are unsignalized intersections and bicycle and pedestrian facilities. For signal-controlled intersections, new developments have been made for left-turning traffic with opposing conflict, right-turning traffic with pedestrian conflict, various lane divisions, and calculation of cycle length. Another objective was to systematize the calculation of different measures of efficiency. The methods are reported as a series of steps in a computation. /Author/ |
