Road safety professionals often face data problems when completing a diagnostic analysis. Whether the analysis is a cursory review of site collision history or an advanced Empirical Bayes network screening, efforts are hindered or results are questioned because the input data is incomplete or uncertain. While there is significant merit to improving data sources, diagnostic analysis cannot wait for data improvements. As a result, there is an urgent need for safety diagnosis tools that are robust in the face of input data limitations. Using two case studies, this webinar will introduce how this need can be met at the network analysis level and at the site analysis level. Both case studies are based on projects completed in Winnipeg during the past 6 months. The Case Studies are the following:
- Case Study 1: Developing Robust Safety Performance Functions for Network Screening When the Traffic Volume and Collision Data has Gaps and Errors.
- Case Study 2: Using Video Analytics to Automatically Detect and Classify Near-Miss Accidents when Collision Data is not Reliable Enough for Diagnostics
Following the case studies, a Q&A will be held on various data limitations faced by webinar participants in completing safety diagnostics and the approaches used to overcome these limitations.
