Mutual Transformation Between OD Matrix and PA Matrix

Abstract:

The relationship between origin destination (OD) and production attraction (PA) matrix was analyzed, and it was pointed out that they often corresponded with different time intervals. An analysis on the limit of peak hour factor argued the necessity of trip classification, and the method to estimate the ratio of each class was proposed based on trip chain and trip purpose structure. Then, with the help of hourly departure and return ratio index, the linear transformation relationship between day long PA matrix and peak hour OD matrix was argued, and the feasibility of PA matrix estimation was demonstrated theoretically. Besides, a human computer interaction interface was programmed. At last, an example was adopted to testify the effectiveness of the findings.
