Section 3: Location Map and PhotographsAnchor: #i1001944
A city or area location map should be prepared to show the relationship of the proposed installation to other traffic signals, highways, business areas, and traffic generators.Anchor: #i1001954
Photographs should be made of all approaches to an intersection, ramp, or any other location being studied for a traffic signal. Generally, only one photograph is necessary for each approach if the photograph is taken from a position approximating that of a passenger car driver approaching the intersection. This would normally be from 46 to 91 m (150 to 300 feet) from the study location. More than one photograph may be required for a particular approach to fully illustrate problems at the location. Peripheral features may also be helpful in defining any operational problems.
The location and approach view direction of each photograph should be indicated on the photograph itself.
