A traffic study completed to determine the quality of operation of a given transportation facility. The Level of Service (LOS) is the resultant of the traffic study and states the transportation facility’s quality of operation.

Provides the highest level of service at the greatest speed for the longest uninterrupted distance, with some degree of access control.

The average number of vehicles traveling in both directions at a specified location along a roadway.

A classification given to federal aid projects or actions that do not have a significant effect on the environment either individually or cumulatively; and for which neither an environmental assessment nor an environmental impact statement is required. Categorical Exclusions do not require extensive levels of environmental documentation.

Provides a less highly developed level of service at a lower speed for shorter distances by collecting traffic from local roads and connecting them with arterials.

The difference in time that a vehicle, pedestrian, or bicyclist spends to travel in absence of interruptions compared to the travel time with interruptions. For this element, average control delay is measured, which is expressed in seconds per vehicle. A prevalent component of delay is control delay, which is the component of delay that results fro [..]

The hourly two-way traffic volume used for analysis and design.

The year the proposed improvement accommodates. Roadway improvement projects are typically designed for 20 years or more in the future.

The investigations that analyze air quality, traffic noise, community impacts such as relocations and access changes, natural resources including protected species and habitats, cultural resources such as pre-historic and historic sites, and land and water contamination issues to determine potential environmental impacts. The proposed environmental [..]
