Real-time determination of spare capacity of routes for enhanced management of congested road network: literature review 2018/19
Knowledge of spare capacity in real-time would lead to enhanced traffic management strategies, such as providing more accurate traveller information and more efficient traffic signal control, such as gating and preemption. A system that can determine real-time spare capacity is an important element to advance traffic management strategies. There are three levels of capacity, as follows: ‘design capacity’ (what the road theoretically should be able to carry) ‘operational capacity’ (what the road is currently able to carry) ‘available capacity’ (how much additional traffic can be served without exceeding capacity). This is a multi-year project that aims to develop the system for determination of real-time spare capacity in four stages as follows: Stage 1: industry review and design capacity (year 1); Stage 2: operational capacity and available capacity application (year 2); Stage 3: stakeholder consultation and system review (year 3); Stage 4: system development (year 3 and 4). This year 1 of the project has the following objectives: identify key elements of the system; identify the potential benefits of the system; develop a methodology to determine design capacity. This report is a draft report which covers the following: update of the literature review; real-time capacity estimation methodology (outline only); case study on an arterial road (Samford Rd) and a motorway (Centenary Hwy).
