SCOOT model accuracy

SCOOT model accuracy
SCOOT model accuracy
This report describes a study into SCOOT traffic model accuracy which has been undertaken at Southampton University for the Transport and Road Research Laboratory. The study has involved a comparison of SCOOT model predictions of traffic flows, queues, delays and associated parameters with similar data collected on-street simultaneously. The SCOOT data has been recorded at the University via a dedicated telephone link with the central SCOOT computer in Southampton. The on-street data has been collected on a link-by-link basis using portable microcomputers for registration number surveys and associated measurements. Some 130 peak and off-peak surveys have been conducted on 17 links of varying characteristics in Southampton. The accuracy of the SCOOT model has been assessed for each site both on a cyclic basis and over longer time periods. Between-site analyses have been aimed at relating SCOOT errors to link characteristics. The sensitivity of SCOOT errors to initial accuracy of validation has also been assessed using computer simulation techniques. The error in SCOOT delay and flow estimates are provided and discussed, as are other results relating to vehicle stops and fixed signal timings.

Abstract

This report describes a study into SCOOT traffic model accuracy which has been undertaken at Southampton University for the Transport and Road Research Laboratory. The study has involved a comparison of SCOOT model predictions of traffic flows, queues, delays and associated parameters with similar data collected on-street simultaneously. The SCOOT data has been recorded at the University via a dedicated telephone link with the central SCOOT computer in Southampton. The on-street data has been collected on a link-by-link basis using portable microcomputers for registration number surveys and associated measurements. Some 130 peak and off-peak surveys have been conducted on 17 links of varying characteristics in Southampton. The accuracy of the SCOOT model has been assessed for each site both on a cyclic basis and over longer time periods. Between-site analyses have been aimed at relating SCOOT errors to link characteristics. The sensitivity of SCOOT errors to initial accuracy of validation has also been assessed using computer simulation techniques. The error in SCOOT delay and flow estimates are provided and discussed, as are other results relating to vehicle stops and fixed signal timings.
