What to Do When ITE Trip Generation Data is Limited or Unreliable

The ITE Trip Generation Manual 12th Edition provides both fitted curve equations and average trip rates for estimating trip generation. However, not all datasets are equally reliable. In many cases, there is either limited data points, or no equation provided. When preparing traffic impact studies for such land uses, engineers and planners must decide: Should […]

Pass-By Trips: What They Are, How to Calculate Them, and How Not to Get Burned

If you already work with trip generation, you know the headline challenge in many Traffic Impact Studies (TIS/TIA): not all site trips are “new” to the network. Some are simply siphoned from vehicles already passing by. Getting this right can change turn lane warrants, signal timing, and mitigation costs. This guide is a practitioner’s deep-dive
