The objectives of the project and most appropriate approach to a school assessment (educational, enforcement or engineering, for instance) must be decided based on the specific features of the local area. This will be identified from site visits and input from the school community; a multiple assessment approach is always encouraged.


Consistency is key. Getting clear results is one of the most important aspects of the project, and they depend on the objectives defined for the project. Obtaining consistent, reliable data throughout the project will facilitate analysis and make comparison between the different stages much easier. It will also prove valuable when it comes to tracking the progress of the project, as demonstrated by the following three stages:

  • Baseline assessment: data and images must be collected as the project starts, to have a baseline for comparison with the other stages
  • Changes: once an approach has been decided on (such as developing an educational approach or implementing infrastructure change), the team can undertake a scenario analysis to test the most effective solutions
  • After assessments: after the modifications are implemented, the locations must be reassessed to compare the results with the baseline and track the impacts of the project
Star Rating for Schools CAA School Safety Zone
Data collected 28 road attributes, as crossing facilities, flow, speeds, sidewalks, traffic lights, delineation, number and width of lanes. Over 25 behaviours and six different offender types (i.e. vehicles, school busses, motorcyclists, trucks, pedestrians). Behaviours can be customized to region.
Processing system The attributes are uploaded to the SR4S web application and combined through the iRAP Pedestrian Model The behaviours are tracked in the school zone safety tool. Tool is built on a WordPress system.
Data output The road attributes collected are combined and generate a Star Rating for each location assessed, where the least safe locations are rated as 1-star and the safest are 5-stars, generating a risk score that pedestrians are exposed to on that specific location. The school zone safety tool collects data on behaviours in school zones. The data can be sorted by offender type (vehicle, bus, motorcycle, trucks, pedestrian, cyclist, etc.), vantage point in the school zone (left corner, front of school, etc.), date, time and school zone. Data is housed in a database that can be downloaded and analyzed by the user or stakeholders (schools, governments, etc.).
How to use the results
  • Prioritise locations to receive road upgrades based on ranking the Star Ratings.
  • Through the SR4S Demonstrator, data collectors can test different scenarios of road upgrades and identify a cost-effective set of interventions.
  • Compare Star Ratings before and after road upgrades to measure their road safety impact.
  • Identify dangerous behaviours in one or multiple school zones
  • Create public education campaigns to help raise awareness of unsafe driving behaviours in school zones.
  • Educate drivers and pedestrians about safe practices in school zones.
  • Share data with decision makers to improve safety in school zones.
