1-1091 Improving variable speed limits. Increasing VSLs for lane diverts and prior to a total closure

Description

Highways England is currently undertaking a programme of improvements to Variable Speed Limits (VSLs) on the motorway and all-purpose trunk road network. This is to improve the appropriateness of both mandatory and advisory VSLs, based on safety and customer insight. As part of the continuing VSLs programme and based on recommended improvements from a comprehensive review of VSLs, Highways England is looking to set-up a contract for the provision of consultancy support to investigate whether VSLs set with lane-divert aspects and VSLs prior to a total closure can be increased, and if so, should they be increased. Technical Consultancy support is required to complete the following: Map and understand current signal sequences for lane diverts and total closures. Develop, conduct and analyse simulator trials. Complete a GG104 safety risk assessment. Design a methodology for an on-road trial
