Streamlining road safety risk mapping and intervention programming on local networks: the Northland transportation alliance risk mapping application

Crash risk is only one of the necessary metrics that local authorities require to analyze road safety risk and to plan and prioritize intervention programmes on their networks. Outputs of such analysis is often aggregated and not stored alongside the outputs of other important metrics and frameworks. Abley Transportation Consultants have developed an interactive application for the Northland Transportation Alliance that combines various risk analyses and metrics. Interactive analysis tools and the ability to overlay different metrics allows for an increased understanding of crash risk and aid efficient and robust planning for intervention programmes.
