The CityLink tollway uses two tunnels, each of which is several kilometres in length, to divert traffic away from Melbourne city centre. In order to provide a safe environment there needed to be a means of enforcing appropriate driver behaviour. Automated enforcement technology was needed because the limited width of the tunnels precludes the use of traditional policing techniques. The challenge was to design and implement a safety camera system which would improve road user behaviour while also providing high levels of performance and reliability in an environment where there is minimal access to operational equipment. The project was structured into two stages, a pilot programme and a roll-out phase. The design process used for this project was derived from a system engineering methodology with an emphasis on management of risks throughout the project lifecycle and stakeholder involvement at all major decision points. This paper presents results showing the trade-offs between major system design parameters in delivering the desired levels of overall system effectiveness.
