Safer, Better Streets – Highway improvement Prioritisation



Purpose of Policy

To ensure that highway infrastructure relating to concerns around traffic speeding, traffic volumes and pedestrians crossings are provided on the basis of impartially assessed demonstrated need.




  1. When a request for street improvement as a result of concerns about pedestrians safety, speeding traffic, volumes of traffic or general traffic related issues are received, an initial assessment will be undertaken to determine if the site meets the agreed pre-qualification criteria, as follows:


Pre-qualification criteria

a sample one hour count of pedestrians and vehicles will be undertaken during the busiest time and only sites with a sample PV2 value of greater than 0.2 x 108 will be put forward for full assessment.

OR if speeding traffic exceeds 20 % above the existing speed limit during an hour’s observation.

OR   if traffic volumes exceed 250 vehicles per hour during assessment.


  1. All sites meeting the pre-qualification criteria set out in (1) will be assessed in detail and prioritised using an approved assessment procedure that takes into account factors such as pedestrian casualties, speed limits, severance, access to schools and existing conditions and LCWIP priority. See table 1 below.


  1. The type of facility constructed will be determined by site assessment bearing in mind the site characteristics including casualty history, vehicle speeds and difficulty of crossing. And design in accordance to latest Department for Transport guidance including LTN120.



note on PV2

PV2 gives an impartial measure of the need for a pedestrian  improvement  at any site by determining the number of vehicles and pedestrians using the area; it is nationally accepted and has been tried and tested over many years.  Using a pre-qualification criteria ensures that detailed assessment is only undertaken for those sites with a proven need and reduces the impact on limited resources.


Types of Improvements





Process Flow Chart



Safer, Better Streets – Full Assessment Scoring Sheet.









Improvements for Mobility Impaired
Score 2 for crossings specifically requested to improve conditions for mobility impaired



Routes to School-  
Score 3 for sites specifically identified as an issue with school related traffic 



Access to Public Transport 
Score 2 for sites which will improve access to public transport 



Reduction of Severance
Score 2 for sites which reduce severance (e.g. to serve sole local store / shopping area or where a residential area is severed by a heavily trafficked A or B class road



Pedestrian & Cycle Collision
Score 3 for each  fatality 
Score 2 for each serious
Score 1 for each slight  casualty 



Other vehicle collisions * 
Score 3 for each fatality 
Score 2 for each serious casualty 
Score 1 for each slight casualty 



Road Width
Score 2 for roads over 9m
Score 1 for roads between 7 and 9m



Actual Speed
Score 3 for roads >20% than posted speed limit

Score 2 for roads between 0-20% higher than posted speed limit.




Footpaths and Cycle Routes
Score 1 for sites which serve an existing designated cycling or walking route such as the National Cycle Network, bridle path or footpath.



Street Lighting
Score 1 for sites with no street lighting
Score 0.5 for sites with existing but sub-standard street lighting



Active Travel  
Score 1 for sites that will clearly improve active travel  in an area, thereby resulting in additional pedestrian and cycle movements 



Score 1 for sites that will clearly improve the ‘walkability’ of an area, thereby resulting in additional pedestrian movements



Links to South Downs
Score 1 for sites that create a new link to the South Downs National Park



Average PV squared value (busiest four hours)
Score equals average PV squared x 10 (e.g. PV2 of 0.25 becomes score of 2.5)



Reduce the impact of vehicles using inappropriate routes particularly on residential roads

Score 3 for excessive non residential traffic in residential areas 

Score 2 for moderate traffic in residential areas  

Score 1 for light traffic in residential areas. 




Identified as a Council priority route in LCWIP – 

Score 2 for each that applies score 3 for each if it’s an LCWIP Priority. 

Neighbourhood Priority Area 

Local links for improvements 

Area based treatments  

Strategic network improvements
