Pedestrian Safety: A Cost-Benefit Analysis and Report |
|
The need for a traffic control signal shall be considered when an engineering study of the frequency and adequacy of gaps in the vehicular traffic stream as related to the number and size of groups of school children at an established school crossing across the major street shows that the number of adequate gaps in the traffic stream during the period when the children are using the crossing is less than the number of minutes in the same period (see Section 7A.03) and there are a minimum of 20 students during the highest crossing hour.Before a decision is made to install a traffic control signal, consideration shall be given to the implementation of other remedial measures, such as warning signs and flashers, school speed zones, school crossing guards, or a grade-separated crossing.
Observation of the crosswalk at Manchaca and Prather indicates that between 150-200 students use the crosswalk between 7 and 9 a.m., and between 100-150 use it between 3 and 4 p.m. During the 7-9 a.m. period, observers counted 68 gaps in the traffic stream adequate to allow crossing. Between 3 and 4 p.m., 72 such gaps were counted.
