Traffic modelling has been updated to reflect more than 5300 additional dwellings in Epsom & Ewell, but there will also be a lot more dwellings in Reigate & Banstead, Mole Valley that will generate more traffic in Epsom and Ewell. No measures are planned to improve the flow of traffic, so it can be expected that the traffic will continue to get worse for the next 15 years and more. There are plans to reduce traffic flow :- less lanes in Epsom High Street, traffic free Ewell High Street. The list is very long of the roads and junctions with high levels of traffic and delays.

Epsom and Ewell Local Plan – Strategic Transport Model
Assessment Report: Post Hearing Addendum Results and Analysis
Scenarios
The presented results represent modelled forecast traffic impacts on highways for the forecast year 2040 taken from the Local Model unless explicitly stated, for the two scenarios:
▪ 2040 Do-Minimum. This includes completions and commitments within the borough since 2019, significant recent completions and commitments outside of the borough, and natural traffic growth
▪ 2040 Do-Something. This is a copy of the 2040 Do-Minimum scenario plus Local Plan allocation sites and windfalls (post hearing).
To understand the impacts of the Local Plan sites, the Do-Something scenario is compared with the Do-Minimum
Local Plan Site Allocations
Site Allocation Total 4405
Windfalls 922
Total new dwellings 5327 (between 10,000 and 15,000 more people)
Categories
C Stable flow, at or near free flow 20-35 sec 15-25 sec
D Approaching unstable flow 35-55 sec 25-35 sec
E Unstable flow, operating at capacity 55-80 sec 35-50 sec
F Forced or breakdown flow ≥80 sec ≥50 sec
The roads which are shown to have maintained a category of D (forced or breakdown of flow) between the Do-Minimum and Do-Something scenarios, are as follows:
▪ A24 Dorking Road, Epsom
▪ A24 London Road, Ewell
▪ A232 Cheam Road, Ewell
▪ A240 Reigate Road, Ewell
▪ B284 Chessington Road, West Ewell

▪ Exit from Ashley Centre onto A24 Ashley Avenue, Epsom (PM peak hour only)
▪ Exit from Ebbisham Centre Car Park, Epsom (PM peak hour only)
▪ Dulshott Green (AM peak hour only)
The roads which are shown to have declined in LoS from a category of B to C (stable to unstable flow, operating at capacity) or C to D (unstable flow, operating at capacity to forced or breakdown of flow) between the Do-Minimum and Do-Something scenarios, are as follows:
▪ A232 Cheam Road, Ewell (PM peak hour only, C to D)
▪ A24 Dorking Road, Epsom (PM peak hour only, C to D)
▪ A24 South Street (PM peak hour only, C to D)

▪ The Avenue, Stoneleigh (B to C)
▪ Langley Vale Road (C to D)
▪ The Avenue (AM peak hour only, C to D)
▪ Lower Court Road (AM peak hour only, B to C)
▪ Temple Road (B to C)
The majority of junctions in the Do-Minimum scenario have available capacity during both time periods. Figure 33 shows all junctions with a LoS of C (stable flow, at or near free flow) or worse in the Do-Minimum scenario and shows junctions situated on major routes, including the A24,A240, A2022, B284, B290 and B2200, are under pressure with seventeen junctions in the AM peak hour and fifteen junctions in the PM peak hour with junction delay at a level which is either approaching unstable flow, or already experiencing unstable or breakdown flow:
▪ A24 Dorking Road junction with Woodcote Road, Epsom
▪ A24 East Street junction with Kiln Lane and Dirdene Gardens, Epsom
▪ A24 Ewell By-Pass junction with B2200 Cheam Road and A232 Cheam Road, Ewell
