The FLOW Impact Assessment Tool

The FLOW Impact Assessment Tool is a holistic technique for evaluating transport improvements. The tool has been designed to provide decision-makers with more information on transport improvement projects’ impacts and benefits compared with simply facility-based multimodal transport analysis. The FLOW Impact Assessment Tool considers mobility, environmental, societal, and economic impacts. It also recognizes that transport is not the only consideration when decisions are made about improving the transport system.

This tool will help achieve the goal of the following objectives

  • Less Contamination
  • Less Emissions
  • Less Traffic Noise
  • Connectivity and Inclusion
  • Healthy Destinations
  • Less Traffic Violence
  • Active Transportation
  • Green Space

Estimation Technique

The FLOW Impact Assessment Tool assesses the impact of walking and cycling measures on traffic flow and congestion before and after the strategy is implemented.
The qualitative results reveal if the volume of traffic has decreased. Additionally, the estimation will quantify the effort needed to lessen traffic flow and evaluate how walking and cycling initiatives would affect congestion.
