OD DATA ESTIMATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an OD data estimation method for obtaining OD data close to reality by using the actual number of traveling vehicles measured by vehicle sensors at a plurality of spots and shortening the time required for obtaining the OD data close to the reality. SOLUTION: An OD data estimation device 1 determines whether or not the OD data supplied to a simulation part 11 are the OD data close to the reality on the basis of a simulation result and observed traffic volume, repeatedly corrects the OD data by using the observed traffic volume or the like when the OD data supplied to the simulation part 11 are not the OD data close to the reality, and generates corrected OD data with the high possibility of being close to actual OD data without performing simulations. Then, the corrected OD data close to the reality are supplied to the simulation part 11 and the simulation is performed. COPYRIGHT: (C)2005,JPO&NCIPI
