Increase cycle length for pedestrian crossing
Countermeasure ID: 4115
Description: Increase the total cycle length to lengthen pedestrian crossing time.
Prior Condition: The cycle lengths of many of the intersections on Queens Boulevard (a 12-lane thoroughfare) and Ocean Parkway (has a central 7-lane roadway, two service roads, and two medians with trees) were increased as a traffic safety countermeasure: from 120-second to 150-second on Queens Boulevard, allowing an additional 20-second walk time for pedestrians crossing the very wide main street, and from 90 to 120 seconds on Ocean Parkway, allowing an increase in pedestrian crossing time from 6 to 17 seconds.
