What would make the biggest difference to reducing the ‘Killed and Seriously Injured’ (KSIs) on the roads in East Sussex ? The answer looks like 20mph. This has been shown to be true in Europe and the UK. So why is East Sussex failing to understand this and will the May 2025 County elections make a difference to the approach?
ESCC Current Policy
One of the ongoing issues within East Sussex County Council (ESCC) is their determination to stick to their current policy PS05/02 towards 20 mph zones and limits. There have been numerous motions, from opposition councillors, to change their approach but all have failed. This has also meant that in the latest list of planned improvements there are none around 20mph.
Elsewhere in UK
So what would a lower limit of 20 mph do? Remembering that most higher speed limits, such as 40, 50 and 70 mph would stay the same.
-
- Wales – 20 mph in Wales achieved a 23% reduction of KSIs for the country as a whole
- London 20 mph in London achieved a 56% reduction.
Similar reductions have been seen in parts of Scotland and councils such as Oxford. It would appear that across the UK nothing has made as much of a difference to reducing KSI figures as 20mph .
One of the concerns is that drivers will not accept the 20mph. However research from DfT shows poor compliance at higher speeds. Plus having some vehicles been driven at 20mph may well affect the behaviour of others
Even if the number of incidents stayed the same the severity of injury is less, if the speed limit is reduced.
ESCC overall approach
So now it is worth examining neighbours, where East Sussex is worse than equivalent councils
Source West Sussex
So one view, might be that ESCC are trapped by their own bureaucracy, in reducing all their interventions to very small scale schemes. This does not have a major effect on the overall KSIs and keeps East Sussex at 150% (See above) of the England KSI average per mile. Currently large sums are spent on consultation, Traffic regulation orders, match funding, sifting, rejecting, reviews and very little on delivery and construction. This is not the most cost-effective option.
The main arguments put forward by ESCC are:-
-
- 20 mph limits only reduce speeds by 1 or 2 mph
- There will be a greater burden of the Police
- The ESCC targeted approach is better
- To be effective, speed limits need to be set at a level which appears reasonable to a driver
- They do not have sufficient funds to meet all the 20mph requests.
Item 4. Above should be re-worded to read, ‘where it is reasonable to a pedestrian’, who is after all the most vulnerable road user.
For more background it is worth reading the full ESCC Scrutiny Review of 20mph You can follow their logic. But the key question is, ‘Has their existing policy made a difference?’ Yes, perhaps safety is increased in very small, selected areas but overall on a county wide basis the numbers are still poor when compared to other counties.
RoSPA
Now let us look at the evidence of how 20 mph limits and zones do make a significant difference. This is an excellent review by the Royal Society of Prevention of Accidents and gives a good analysis of where they have been implemented.
“ 20 mph limits have been shown to reduce traffic speed, although not as much as 20mph zones with traffic calming. However, they are considerably less expensive to implement, which means that wider areas can be covered. They also provide additional benefits, such as encouraging more physical activity, such as walking and cycling. They can also greatly improve the character of a residential area and quality of life of the residents. 20mph limits are most appropriate for roads where average speeds are already low… and use of the road also gives the clear impression that a 20mph speed or below is the most appropriate. “
Local Transport Plan
So is there hope for the future in the Local Transport Plan 4 (LTP4)? Covering up to 2050. The answer is not encouraging, with ESCC sticking to the same mantras:
“The delivery of lower speed limits including 20mph speed limits and zones in the County is done in accordance with East Sussex County Council adopted Policy PS05/02. This policy reflects national guidance and best practice for setting speed limits.”and “The LTP4 policies clearly highlighted that the adopted ESCC Policy PS05/02 is the determinant for setting lower speed limits in the county”

Conclusion
• East Sussex has a much higher than average number of KSIs
• The current approach of small piecemeal interventions, of all types of schemes, is not making enough difference to overall road safety. Spending large amounts resisting and rejecting schemes rather than implementing.
• Higher speed limits do not make for good ‘placemaking’, a requirement of LTP4
It is hoped that the May 2025 Council elections will change the balance of power and result in a different direction.
