Calculating Social Benefit in Travel time considering seasonal and daily variation in traffic pattern

Abstract

Most transportation analysis has hused an annual average day OD traffic pattern for strategic plans both of urban and intercity. However, there is usually big variation in traffic pattern depending on season and day over the year. As the results, analysis results with ADD OD might mislead decision for strategic transportation policy, because the average traffic pattern might not represent well even any one of season and day`s traffic patterns.

This study suggested a method to estimate approximately seasonal weekday and weekend personal OD trips by using the Korean TCS OD data with the AAD OD table estimated by KOTI. The study showed that there was difference in time saving in case of using the AAD OD data from the case of using seasonally and daily varied OD data for same strategic plan.
