Abstract |
A stochastic discrete-event simulation model system for heterogeneous road traffic, which prevails on the Indian highway network, is presented. The original Swedish Road Traffic Simulation Model system, designed for motorized traffic, has been generalized to cover heterogeneous traffic that includes slowmoving nonmotorized traffic. The model has also been extended for narrow roads and covers roadwidths from 3.75 to 13 m with different shoulder types and alignments in flat, rolling, and hilly terrains. Submodels for the basic desired speed, power-to-mass ratio, overtaking gap acceptance and yielding probability distributions, passing speeds, and fuel consumption rates have been calibrated with extensive field data for subsequent validation of the simulation model. The output of the model has been intended primarily (a) to furnish relevant vehicle operating data for appraisal of individual road projects, (b) to constitute background data for a relevant level of service concept, and (c) ultimately to provide a basis for an appropriate policy on geometric design of rural roads in general. The model has been programmed in SIMULA-67 language using Jackson Structured Programming concepts. The results of validation exercises have been convincing; the model should be useful to decision makers for obtaining reliable data for investment analysis. Language: en |
