SCOOT MMX Service Pack 1

SCOOT MMX Service Pack 1 provides a facility to assist with improving the Journey Time Reliability (JTR) along key routes.

For many authorities, JTR is a key performance outcome along key corridors. There are many contributing components to JTR including planned interventions (such as roadworks and events) and unplanned occurrences (such as accidents).

Cause and effect are not fully understood, but studies have shown that the saturation of SCOOT corridor links and the self-healing ability of these links are major contributing factors to JTR, so saturation levels (demand/capacity ratios) of corridor links are of significant.

To assist engineers in maintaining JTR, a facility has been developed to help them control the SCOOT link saturation level more effectively. It will be possible to specify a maximum level of saturation for a link or series of links (e.g. 80%) and SCOOT will attempt to maintain the degree of saturation at or below the specified level. This should provide a more outcome-based version of SCOOT.

The facility was originally developed for Transport for London (TfL), where it is called JTR - GOLD (Journey Time Reliability - Games Operation Led Development), to assist them in controlling the journey along key corridors in London. Its first intended application was within the Olympic route network.
