The Introduction to Transportation Planning course will discuss the basic principles of transportation planning. It provides the definitions and objectives of project design and corridor traffic forecasting. It will also examine how equivalent single axle loading (ESAL) forecasting plays into the planning process.
Traffic data sources will be discussed such as permanent continuous counts, permanent continuous classification counts and portable seasonal classification counts.
Definitions will be provided for traffic factors including seasonal factor (SF), axle correction factor, annual average daily traffic (AADT), K, directional distribution (D) and percent trucks (T). Equations will be provided to show how each of these factors relate to traffic forecasting.
