Study Finds Traffic Forecasts Consistently Overestimating Congestion
Researchers from Denmark and Norway have looked at the accuracy of traffic forecasts for road projects. Their conclusion is that the forecasts systematically overestimate traffic growth rates and the resulting congestion effects.
Study: Traffic Forecasts Are Often Inaccurate
In a recent review of the state-of-the-art, two planning researchers conclude that traffic forecasts often fail to accurately predict that demand for new transportation infrastructure.
Study Says Induced Traffic Effect Too Often Ignored
Despite many studies confirming the effect of induced traffic, the effect is often ignored in the transport models used for project appraisal, says a team of Scandanavian researchers creating an extreme bias in the assessment of new projects.
