Traffic control improvements are part of the municipality’s ongoing initiatives to improve road safety.
Accessible Pedestrian Signals (APS)
Accessible Pedestrian Signals (APS) are devices used to allow visually impaired pedestrians to use the ‘walk’ and ‘don’t walk’ signals when they are attempting to cross at a signalized intersection. The APS provide walk sounds such as a ‘coo-coo’ to indicate that it is safe to cross in a north-south direction and a ‘three note melody’ to indicate that it is safe to cross east-west. This directional guidance information is especially important at skewed intersections and at wide multi-lane crossings.
In addition to all new and upgraded signal installations which are equipped with APS, a limited number of installations per year are based on resident requests and supporting infrastructure.
Leading Pedestrian Intervals (LPI)
A Leading Pedestrian Interval (LPI) is a timing option used at signalized intersections to activate the pedestrian walk signal before the adjacent (parallel) vehicle signal, providing a head start to pedestrians wishing to cross. This head start provides an advantage to the pedestrian over vehicles turning at the intersection and can help improve driver yielding behavior. The LPI enables pedestrians to establish their presence within the crosswalk, making them more visible to drivers.
LPIs are most effective at signalized intersections where there is a significant amount of turning traffic, especially left turns, travelling over a crosswalk. Signalized “T” intersections would be priority candidate locations since all traffic exiting the side street would be turning across the main street crosswalks. Consideration is also given to locations where turning traffic encounters limited or no opposing through traffic (i.e. intersections with one-way streets), near schools or seniors’ facilities or where collision history indicates a pattern of vehicle/pedestrian collisions associated with turning traffic.
Rectangular Rapid Flashing Beacons (RRFB)
RRFBs are pedestrian activated crosswalk treatment systems which consist of two rapidly and alternately flashing rectangular amber beacons mounted above the side mounted pedestrian crossing signs.
RRFBs can enhance safety at unsignalized intersections and mid-block pedestrian crossings by increasing driver awareness of potential pedestrian conflicts and by improving driver yielding behavior.
A number of RRFB installations are completed each year including existing marked crosswalk upgrades and new crosswalk locations
