Abstract
Traffic assignment is the process of allocating a set of OD trips to various routes of the transportation network. Usually traffic assignment is made for an entire day. The most common assignment techniques use Q-V curves, which show the speed-volume relationships, in order to take into account the effects of traffic congestion. However, these Q-V curves have been determined ideally or empirically and have not been based on field data.
In this paper we present a new method which can make up a Q-V curve applicable to traffic assignment for an entire day by using the Q-V curve observed for an hour and the hourly variation pattern of traffic.
