The precision of traffic predictions can fluctuate based on a multitude of elements. Studies suggest that forecasts made more recently are generally more precise, with the average discrepancy altering as time progresses. Typically, the actual traffic is approximately 6% less than what was predicted, with an average absolute discrepancy of 17% from the projected figures. Certain factors that enhance the accuracy of these forecasts encompass roads with higher volumes, superior functional classes, shorter durations, and the application of travel models. Moreover, aspects such as unemployment rates and years close to the forecast year opening can also influence precision. It’s advisable for agencies to recognize the inherent uncertainty in these forecasts and perceive them as a spectrum of potential outcomes rather than one definitive result.
