Pedestrian-Detecting Traffic Signals

Pedestrian detectors can activate a pedestrian traffic control device, extend the crossing time for pedestrians already in the crosswalk, and shorten the crossing time if pedestrians have already cleared the crosswalk. Detectors can be pressure mats at the waiting area, infrared or microwave detectors mounted on the signal pole, or video cameras using remote sensor software at … Continue reading Pedestrian-Detecting Traffic Signals

Pedestrian Scramble or Barnes Dance

A pedestrian scramble, or Barnes Dance, is an exclusive pedestrian interval that stops all vehicular movement to allow pedestrians access to cross in any direction at the intersection, including diagonally. During a Barnes Dance, pedestrians can cross at all four crosswalks; during a pedestrian or signal scramble, pedestrians are encouraged to cross the intersections diagonally … Continue reading Pedestrian Scramble or Barnes Dance

Split Phasing

Split phasing divides the green light of a traffic signal into separate phases: one for turning vehicles and another for through-traffic and pedestrians. Guidance Use a five-section signal head with a combination of circular and arrow indications For permissive-only right-turn modes (where pedestrians continue to cross while car are permitted to turn), program the turn … Continue reading Split Phasing

Ban Right Turns on Red

Right turn on red (RTOR) is a policy that permits drivers to turn right during a red light after coming to a complete stop, except where specifically prohibited by a posted sign. This nationwide policy (with the exception of New York City) was adopted by the Federal Highway Administration and Department of Energy in the … Continue reading Ban Right Turns on Red

Accessible Pedestrian Signals

Accessible pedestrian signals (APS) and detectors are designed to accommodate the needs of all pedestrians, including those with vision and mobility impairments. They provide information in nonvisual formats such as audible tones, speech messages, and vibrating surfaces to indicate the appropriate time for pedestrians to cross the street. Guidance Integrate the addition or upgrades of … Continue reading Accessible Pedestrian Signals

Leading Pedestrian Interval

A leading pedestrian interval (LPI) is a 3- to 10-second pedestrian-only phase within a signalized intersection timing schedule that gives pedestrians a “head start” over cars going in the same direction or turning across the pedestrians’ paths. It is displayed by an advance walk indication for the crosswalk during which parallel and turning traffic continue … Continue reading Leading Pedestrian Interval

In-Road Pedestrian Signs

These are flexible signs placed in the median or centerline at unsignalized crossings announcing that drivers must yield or stop for crossing pedestrians. Guidance Install in a location where it does not conflict with traffic patterns or encroach into a travel lane: at the crosswalk on the centerline, on a lane line, or on a … Continue reading In-Road Pedestrian Signs

Advance Stop Lines

Stop lines are used to indicate the point behind which vehicles should stop for a Stop sign, a Stop Here for Pedestrians sign, or some other traffic-control device that requires vehicles to stop. Guidance Stop lines should not be used where drivers are supposed to yield Lines should be solid white lines extending across approach … Continue reading Advance Stop Lines

High-Visibility Crosswalks

Crosswalk markings provide guidance for pedestrians crossing roadways by defining the appropriate paths for them. While basic crosswalk markings consist of two transverse lines, an FHWA study found that continental markings were detected at about twice the distance upstream as the transverse markings during daytime conditions. In the study, this increased distance meant that drivers … Continue reading High-Visibility Crosswalks

Offset Crosswalks

An offset crosswalk is one with a center median that acts as both a pedestrian safety island and means of directing pedestrians to look toward oncoming traffic before crossing the second half of the street. Guidance The crosswalk offset can be a right angle or skewed depending on site conditions Design islands with level cut-through … Continue reading Offset Crosswalks
