6 Rivenwood Phase 2 Movilla Road / Rivenwood Boulevard Systra Ltd has undertaken a capacity assessment of the proposed signal controlled access junction to the development from Movilla Road. This is to ensure that the traffic generated by Phase 1 (1 units) and Phase 2 (24 units) can be accommodated by the proposed junction design. The assessment has been undertaken using the industry-standard software package, LinSig 3. The table below provides the results of our modelling exercise. The results include the Degree of Saturation (DoS) and Mean Maximum Queue (MMQ) for each lane while the overall Practical Reserve Capacity (PRC) and junction delay are provided. A DoS of less than 9% indicates that the lane will operate within practical capacity while a positive PRC indicates that the junction as a whole will operate within capacity.

A more detailed summary of the results has also been provided (see LinSig Summary).
