    Abstract
  • In order to improve the verification precision of resident trip survey, the characteristic of screen line was studied that could form a lot of closed areas in cluster city, and the verification method of resident trip OD matrix based on screen area was proposed according to maximum entropy principle.The relationship between the inner or outer traffic volume of screen area and OD matrix distribution, and the relationship between the OD matrix distribution of screan area and the traffic volume of road segments were analyzed.The difference minimum between the real values and estimation values in screen line segment and screen area was seen as target, and the corresponding model and algorithm were set up.The method was verified by the data of Xi'an urban resident trip survey in 2008.Analysis result indicates that the mean relative error between the assignment volume of verified vehicle OD matrix and observed data is 4.75%, and the maximum error is 12.28% in 519 traffic zones, so the method is valid.
