2.4.2 Existing Operations

During field observations, verify operational items that could not be easily inferred from field traffic data. Below is a list of examples that may be noted during field observations:

Existing roadway and traffic elements, including traffic control types;

Speed limits (e.g., how often speed limits are changing, location of speed limit signs, operating speeds);

Queuing and notable issues, such as queuing out of turn bays or on ramps;

Traffic signal heads, including pedestrian signal heads;

General operation of the traffic signal (e.g., sequence, phasing, cycle lengths, de facto cycle lengths if running free);

Left turn phasing (permitted, protected [leading or lagging], protectedpermitted, flashing yellow arrow);

Land use and zoning in the vicinity of the project;

Lane utilization along each approach;

Turning movement speeds at nonconventional turning angles; and

Atypical driver behavior, such as drivers making a right turn at an intersection, followed by immediate U-turns at a downstream location
