Traffic Assessment - Renfrewshire Council

4.34 The results indicate there will be a significant improvement to the operation of Station Road and
while it is noted the maximum RFC is 0.90, the associated maximum queue is only 7 vehicles long.
When considering the analysis has been undertaken using historical traffic flows that are greater
than the current traffic volumes on the A8, JMP would consider the proposed mini-roundabout will
operate with no significant problems and generally within capacity.
4.35 This is supported by the average RFC and queue for Station Road which will be 0.78 and 4
vehicles respectively which suggests the junction will operate within capacity for the majority of the
day.
4.36 Furthermore, not only will a mini-roundabout mitigate the traffic impact of the proposed foodstore, it
will address the concerns of Renfrewshire Council with regards to the restricted visibility onto
Greenock Road, thereby improving road safety for existing and future road users.
Station Road Railway Bridge Underpass
4.37 As indicated earlier, a rail bridge crosses Station Road which imposes a width restriction on the
approach to the proposed development site. Given the anticipated increase in the volume of traffic
and pedestrian movements, it is proposed to provide traffic signals to manage the flow of traffic and
provide a safe facility for pedestrians. An indicative layout is provided in Appendix H.
4.38 The results of the Linsig analysis for this facility are provided in Table 4.7 below. We can confirm
the analysis has been undertaken with a pedestrian stage called every cycle and a cycle time of 60
seconds.
Table 4.7 Station Road Underpass Traffic Signals
Base plus Development
Link Number Lane Description DoS (%) Max Q
1/1 Station Road South Ahead 41.0% 3
2/1 Station Road North Ahead 42.5% 2
DoS% = Degree of Saturation where 90% is considered to be the practical capacity
4.39 The results clearly indicate that the traffic signals would operate well within capacity during the
weekday PM peak period.
Sensitivity Test – Rossland Crescent
4.40 As the land uses associated with the village centre will be of a benefit to the existing residents of
Bishopton, the Team are keen to maximise the accessibility and integration of the centre and
community facilities with the existing village and are therefore, investigating the option of providing
an alternative vehicular link via Rossland Crescent that would complement the proposed walking
and cycling link.
4.41 By undertaking a review of travel times (utilising Google route finder) in consideration with the
potential delay incurred by the various traffic signals, we have sought to quantify the area of
existing Bishopton Village where travel via Rossland Crescent may be a viable alternative to the
community facilities.
