Concerns are raised around traffic Forecasting of Strategic Models. In particular, the phasing of development.
Traffic Forecasting of trips rates & mode shares.
Design and capacity of the new A120 junction.
Concerns over noise and air pollution from highway network on new development.
Concerns that drainage will be into the highway network system.
The base year CTM represents a 2019 Base Year and will reflect the pattern of trip making and travel behaviour that existed prior to the Covid-19 pandemic.
There are no detailed forecasts available to review and there has been no separate assessment of the traffic generated by the TCBGC proposals. Therefore, there is no information available in order to assess the impact of TCBGC on the highways network.
Further review of the evidence base work needs to be undertaken.
If the link road is to be delivered in two parts, impact on the highway network must be assessed for that time until the new junction is complete.
Proposed working with the Councils to address noise and air pollution issues. Consideration should be given for a bespoke Policy on noise and air pollution.
It is recommended that the advice on proportionate accounting for Covid 19 in prior calibrated models as set out in Appendix B of TAG M4 (Forecasting and uncertainty) issued in May 2023, should be taken into account to adjust the 2019 CTM matrices.
Forecasts prepared using CTM would require sensitivity testing to take account of the greater uncertainty arising from Covid-19.
When preparing forecasts from assessing TCBGC, to comply with advice set out in paragraph B2.3 of TAG M4 issued May 20223 sensitivity testing should be carried out to assess the further potential for change with respect to the long-term impact of Covid 19. This sensitivity testing should be carried out in line with best practice set out within DfT’s Uncertainty Toolkit.
Further information is required on modelling. See representation for further details.
