MODELLING PEAK SPREADING IN CONTINUOUS TIME

摘要: In the 1994 SACTRA report, changing departure time was recognised as an important response to both increasing congestion and transport policy, second only routing changes. Unfortunately, techniques available model choice peak spreading have suffered from conceptual drawbacks, generally related dimension. For example, many of existing simulated PERIOD (peak/off-peak, or hour/shoulder), whilst in reality shifts may be expected much smaller orders magnitude, take place continuous time. Techniques been developed past for a single bottleneck. Such methods assume personal preferred arrival times (PATs) dependent on, say, trip purpose characteristics, scheduling trade-offs between travel duration, early late arrival. This paper presents implementation these ideas into network wide application, generalising individual choices more aggregate relationships at origin-destination level. Software has interface with standard commercial assignment software (SATURN, TRIPS, CONTRAM), ready application practice. The addresses following issues: (1) background; (2) estimating times; (3) development software; (4) operational issues application; (5) results tests on real-life networks. DETR funded research project progress since April 1998, genuine new material based achievements up till now is presented. A remaining task study comparison current practice (mainly logit models time). covering abstract see ITRD E105584.
