The Calculation of the Punctuality Rate between Bus Sites Based on AVL Data

摘要

Nowadays, people pay more and more attention on the service quality of public transportation, as well as the research on situations of public transportation arrival on time. This article analyses the feature of AVL data from the GPS system on the bus and raises the calculation model of bus stop-time. What's more, it gives the clear definition of Adjacent Sites Punctuality Rate (ASPR) and builds a more accurate calculation model with extreme value theory, which is used to evaluate the bus running between adjacent sites. Then it uses the AVL data of Shanghai's No.49 bus to test the model's practicality.
