Changing Concepts of Level of Service in the Some 1985 Highway Capacity Manual: Examples
T he 1985 Highway Capacity Manual (HCM) introduces new concepts of capacity and level of sarvice that are, in some cases, radically different from those used in previous editions of the HCM.’ A previous article has presented and discussed these basic concepts and their implication on interpreting capacity analysis results.’ This article focuses on the three primary examples of markedly differen...
متن کاملThe 1985 Highway Capacity Manual and Road User Costs for Two - Lane Roads
R oad user cost is an important consideration in highway economic analyses. The two main components of this cost are (a) motorvehicle running cost and (b) travel time. Highway engineers and economists know that, for road user costs (running costs plus travel time), lower traffic volume usually provides the least unit cost; as volume increases, the cost to the user increases because of congestio...
متن کاملPartial Elliptical Two-Regime Speed-Flow Traffic Model Based on the Highway Capacity Manual
There have been several attempts to describe traffic flow behaviour by modelling the relationship between the main variables describing traffic such as speed, flow and density. Some of these models are based on simplistic assumptions and therefore, they are far from being accurate in representing the whole range of traffic conditions (e.g. from free flowing to congested situations). This paper ...

متن کاملEntrance Capacity of an Automated Highway System
T his paper evaluates the entrance capacity and queueing delay for Automated Highway Systems through use of simulations and analytical modeling. Queueing statistics are also used to determine the sustainable capacity of alternative concepts, taking trip length distribution and spacing between ramps into consideration. Based on safety-spacing head ways (produced in a separate analysis), the mos...
