CALCULATION MODEL AND ALGORITHM DESIGN FOR RAILWAY PASSENGER OD-MATRIX

Abstract

This paper studies the model and algorithm of railway passenger's OD-matrix estimation, based on actual passenger train information, such as: train manifest, train capacity, route and attendance rate etc. For acquiring the railway passenger's OD-matrix matching with factual traffic flow, this paper utilizes the method of traffic flow allocation suit to railway fieldwork, aim at bias rate between theory traffic flow and factual traffic flow and make use of error correction to iteratively compute, until get a satisfying solution.
