Both crash rates and traffic volumes at an unsignalized urban intersection have steadily increased during the past few years. Briefly describe the types of data you will collect and how you will use those data to justify the installation of a traffic signal at the intersection.
What will be an ideal response?
To justify the installation of a traffic signal, traffic volume data, pedestrian
volumes, accident data, distance on the minor street between the nearest rail of the
track and the STOP or YIELD line, and rail traffic would be collected. These data
would be compared with the signalization warrants in the MUTCD to determine
the need for the signal. The warrants pertain to:
? Minimum vehicular volume
? Interruption of continuous traffic
? Minimum pedestrian volume
? School crossing
? Progressive movement
? Crash experience
? Systems
? Combination of warrants
? Four-hour volume
? Peak-hour delay
? Peak-hour volume
? Intersection near a grade crossing
