Kent Terrace Cycleway
Thank you for your request made under the Local Government Official Information and Meetings
Act 1987 (the Act), received 15 August 2023. You requested the fol owing information:
1. Traffic Model ing, Reporting and Calculations (Including SIDRA analysis) as it relates to the
newly instal ed cycleway along Kent Terrace. To understand the predicted level of service
decrease/increases for the following intersections:
a) Oriental Parade and Cable Street.
b) Kent Terrace and Courtenay Place
c) Kent Terrace and State Highway 1
2. What validation has been completed by WCC, since the instal ation of the cycleway including
independent road safety audits and verification of the predicted level of service
decrease/increases.
Wel ington City Council has
granted your request for information. Please see the below response
to your questions.
1. Traffic Modelling, Reporting and Calculations (Including SIDRA analysis) as it relates to the
newly instal ed cycleway along Kent Terrace.
Appendix 1 contains the modelling for intersections Kent Terrace and Courtenay Place and Kent
Terrace and State Highway 1. Cable Street and Oriental Parade were not changed significantly
enough to warrant the model ing resource.
2. What validation has been completed by WCC, since the instal ation of the cycleway including
independent road safety audits and verification of the predicted level of service
decrease/increases.
The transitional approach al ows us to implement changes to the roadway quickly and with
adaptable materials, so generally minimal modelling is done on these projects as we can respond
to issues as needed. On Cambridge Terrace we have already been able to address some
congestion issues caused by the initial storage space in the Elizabeth St turn bay.
While we have been preliminarily monitoring queue lengths and any pressing issues, most of the
post-instal ation evaluation wil not begin until 6 to 8 weeks after instal ation as users need this
time to adapt to the new layout and flows to normalise. However, we can share that the predicted
queues on Cambridge Terrace at Vivian Street are notably shorter than predicted by model ing.
Further qualitative feedback wil be col ected during the feedback phase of the project beginning
mid-September. While not completed post instal ation, we have included the latest independent
road safety audits on the 90% designs which may be of interest to you.
Below are the documents that fal in scope of your request and my decision to release the
document.
