In traffic engineering, the K-factor is a critical parameter used in roadway design and traffic analysis. It represents the proportion of Annual Average Daily Traffic (AADT) that occurs during the design hour, and it allows engineers to size and evaluate roadways for their most critical operating conditions. Trying to calculate a traffic signal warrant? Try […]
A transportation (travel demand) model is a quantitative framework that forecasts how people and goods move through a region under different land-use and network scenarios. Done well, a model becomes a decision engine: it helps test road and transit projects, pricing policies, and growth plans before spending real money. This guide covers when you actually
Sight distance is one of the most important considerations in road design. It represents the length of roadway visible to a driver, ensuring there is enough distance to perceive, react, and stop safely when encountering obstacles or conflicts. Inadequate sight distance can lead to unsafe conditions, higher crash risks, and poor traffic flow. This reference
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
