Please provide the following information relating to the Dryden Road, Exeter consultation and the decision to remove the lightly segregated cycle route option:
1. Economic Appraisal
Please provide any cost-benefit analysis, return on investment (ROI), or value-for-money assessment (including any WebTAG or equivalent appraisal) for:
a) The lightly segregated cycle route option (requested by HATOC on 9 October 2025), which was rejected as ‘prohibitively expensive’ and ‘not viable’;
Devon County Council does not hold this information as no economic appraisal exercise to compare to benefits/ROI has been undertaken at this stage. Only Indicative costs have been calculated.
b) The retained options (Options 0, 1, 2, and 3).
Please also provide any criteria, thresholds, or benchmarks used to define ‘prohibitively expensive’.
The lightly segregated cycle route option could not be delivered due to width constraints.
2. Assessment of Retained Options
For each of Options 0, 1, 2, and 3, please provide:
a) Estimated whole-life (including maintenance) costs;
Only Indicative construction costs have been calculated, which are set out on the consultation page, being:
| Option 1 – Bus / authorised vehicle gate | Option 2 – One-way arrangement (Westbound) | Option 3 – Two-way vehicles and two-way cycle facility | |
| Cost | Low | Medium | High |
Criteria: Indicative Cost – Low (£0 to £100k), Medium (£101k – £200k), High (£201k-£1m), Very High (£1m upwards).
b) Any assessment of impacts on motor vehicle journey times, including methodology (e.g. traffic modelling, assumptions, baseline data) and quantified results;
Devon County Council does not hold this information. This is because journey times have not been assessed.
c) Any assessment of impacts on vulnerable road users (including cyclists who require separation from traffic), including journey time, safety, and level of service, with details of methodology and assumptions used.
Indicative designs have been developed in respect to the Department for Transport’s (DfT’s) Inclusive Mobility Design guidance and DfT’s LTN1/20. Specific assessments have not been undertaken at this public consultation stage.
