Traffic Safety Devices

Angled Crosswalks

Provides a center refuge for pedestrians. Forces pedestrians to look at oncoming traffic before crossing entire roadway

Back-In Diagonal Parking
Back-in diagonal parking allows drivers to back into an angled parking space resulting in safer access to sidewalks and better visibility while exiting the space.

Bike Boxes
A bike box is a bike staging area designed to prevent bike/car collisions at intersections. It allows bikers to wait in front of motorists at a red light to make them more visible and prevent collisions caused by a motorist turning across the path of a cyclists traveling straight. See video.
Stutter Flash 
A stutter flash increases driver awareness of potential pedestrian/vehicle conflicts at mid-block ped. x-ings and intersections w/out traffic signals. Cars should stop when the signal is flashing and allow the pedestrian to cross. See video.

Buffered Bike Lane
A buffered bike lane is a bicycle facility that is separated from adjacent travel lanes or parked cars by a wide pavement marking. See video.
Green Bike Lane 
Green bike lanes use green-colored pavement to increase the visibility of the bicycle lane in places where there is potential for conflict with motor vehicles. See video.

Shared lane markings or sharrowsidentify where bicyclists should position themselves within the travel lane. Where sharrows are present, bicycles and cars share the lane. See video.
Bike Traffic Signal 
A bike traffic signal aids the safe and efficient movement of bicycles through intersections that serve high volumes of bicycle and motor vehicle traffic by giving both types of users a separate signal phase to travel through the intersection. See video.
Pedestrian-Activated Red Light
A Pedestrian-Activated Red Light, or pedestrian hybrid beacon (PHB), is a traffic control device to help people who walk and bike to cross busy streets safely. See video.

Speed Humps
Raised areas of asphalt designed to reduce vehicle speeds. Speed humps are typically 14 feet long and 3 inches high. Speed humps help by reducing vehicle speeds and enhancing the pedestrian environment at pedestrian crossings.

Raised Intersection 

Flat raised areas covering an entire intersection. Often built as a pedestrian crossing to slow vehicle traffic. Raised Intersections reduce vehicle speeds, enhance the pedestrian environment, and improves vehicle and pedestrian safety.

Raised Crosswalk
A flat-topped speed table built as a pedestrian crossing. May be constructed of asphalt, concrete or a combination of different materials. Raised crosswalks reduce vehicle speeds, raise driver and pedestrian awareness of crossing location, and enhance pedestrian environment.

Speed Table
Flat-topped speed hump often constructed with brick or other textured materials on the flat section. They slow vehicle traffic approaching the table to enhance the pedestrian environment. The wheelbase of a typical passenger car will fit on top of a speed table. Speed tables reduce vehicle speeds, enhance the pedestrian environment at pedestrian crossings.
Traffic Circle 
Raised islands placed in the middle of an intersection to calm traffic. Motorists are required to slow to a speed that allows them to comfortably maneuver around the circle. Traffic circles manage traffic at intersections where volumes do not warrant a stop sign or a signal. They also reduce crash occurrence at the intersection of two local streets, and reduce vehicle speeds at the intersection.

Street designed to slow traffic by requiring motorists to follow a one-lane serpentine route. Typically, a chicane uses three or more horizontal deflections on alternating sides of the street. The design slows traffic and elicits a cautious response from motorists. Chicanes reduces vehicle speeds, eliminates straight site line, and have a potential to add more landscaping to a street.
Crossing Islands
Crossing Islands enhance pedestrian crossings, particularly at unsignalized crossing points, reduce vehicle speeds approaching pedestrian crossings and highlight pedestrian crossings.

Chokers slow vehicles at a mid-point along the street and they create a clear transition between a commercial and a residential area. Chokers narrow overly wide intersections and midblock areas of streets and
add room along the sidewalk or planting strip for landscaping or street furniture.
Crub Extensions
Curb extensions improve safety for pedestrians and motorists at intersections and
increase visibility and reduce speed of turning vehicles. They also
encourage pedestrians to cross at designated locations, prevent motor vehicles from parking at corners, and
shorten crossing distance and reduce pedestrian exposure.
