A New Way to Measure Road Safety That Doesn’t Wait for Crashes to Happen
In order to improve road safety, decision makers need accurate information about their city’s streets. Traditionally, road safety analysis has relied on historical data of actual crashes. However, the drawback of this “crash-based approach” is that it is reactive—we have to wait for crashes to occur in order to prevent them. And in developing countries, this data is often poor-quality and limited.Instead of analyzing past crashes, a more proactive approach is to analyze traffic conflicts.
