Analysing High Risk Roads

One of the key responsibilities of local authorities and police forces is to review locations where there are high collision rates. Understanding which roads are high-risk and which are safer than average is difficult without access to large datasets, and a comprehensive set of analytical tools. RiskMap provides quick and easy-to-interpret answers which has attracted attention from many clients in different sectors keen to see place-based risk analysis on roads, near transport hubs, or for individual road user groups.

Agilysis have been supplying local roads collision analysis for a number of years with customers from local authorities as well as large fleets. Our methodologies have been honed by constant conversations with end users and an increased use of cutting-edge technology. We have advanced our methods sufficiently to be able to provide a large quantity of analysis for the whole of GB, or individual areas.
Our data is regularly updated and comes from reliable sources, and we are also able to incorportate custom data supplied by clients subject to negotiation.

  • Metrics per link

  • Total crashes
  • Road length
  • Road class (M, A, B, unclassified)
  • Rurality (urban / rural)
  • Crash density (collisions per km)
  • Risk index (density) by road class and rurality
  • Crash rate (collisions per million vehicle miles)*
  • Risk index (rate) by road class and rurality*
  • Crash counts for individual road user groups (pedestrians, cyclists, motorcyclists, goods vehicles)

    *For roads with traffic count points. Agilysis customers using our modelled traffic flow product can contact us to request a more comprehensive analysis

  • Hotspots

    As a separate layer, Agilysis will also provide a list of the top 50 collision hotspots per area* ranked according to our weighted serverity criteria. These maps highlight specific sections along routes where crash density is highest.

  • Bespoke options available for vehicle and road user types
  • Road environment factors e.g. weather also available depending on client requirements
  • Multiple uses for scheme prioritisation (local authorities), enforcement locations (police), route planning (fleet management), driver warnings (OEM, apps)

    *Local authorities and police forces only, not national
