This report is the final report of the three-year External Vehicle Speed Control project. It does not attempt to summarise all the major findings of the project. The report concludes Phase III of the project. Other deliverables from this phase are D7.2 (Legal Implications of External Vehicle Speed Control) and D16 (Production Issues). The major objective of Phase III has been to prepare an implementation strategy for EVSC, taking into account system costs, predicted benefits, any major disbenefits and timescales for introducing EVSC. This report draws on all the previous work of the project to review the case for moving forward with EVSC and to propose an implementation strategy by which EVSC could be rolled out if such a rollout can be justified. It presents the conclusions from the project concerning the technologies and system architecture for EVSC, the time required for implementation, and the predicted accident savings. The initial benefit-cost analysis carried out at the end of Phase I of the project in Deliverable 6 (Implementation Scenarios), has been revised in the light of the results from the simulation modelling carried out in Phase II on network effects on EVSC and in the light of the behavioural studies of user behaviour with EVSC. The costs of implementation have also been revised, drawing on more recent information about the future costs of the various subsystems required. Chapter 2 of the report reviews some of the implications of the project's research for the implementation of EVSC. Chapter 3 presents the accident savings that are predicted for the major variants of EVSC. In Chapter 4, the network impacts of EVSC as predicted by the simulation modelling conducted by the project are presented. Chapter 5 reviews the economic costs of implementing EVSC and Chapter 6 presents the benefit-cost predictions for the major system variants. A proposed strategy for the implementation of EVSC is presented in Chapter 7 and the conclusions and recommendations of the report are summarised in Chapter 8. (A)
