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 (100 units) and Phase 2 (204 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 90% indicates that the lane will operate within

practical capacity while a positive PRC indicates that the junction as a whole will

operate within capacity.

The results presented in the table above demonstrate that the proposed signal

controlled access junction to the development from Movilla Road will operate

well within capacity during both the weekday AM and PM peak period with

ample Practical Reserve Capacity.

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

Summary).
