For Mass Transit Platforms:

Thin black strips before platform tiles:

The purpose of the tactile pre-warning strips is to create a color contrast between the detectable warning tile and the surrounding platform surface. Placed purposefully before the warning dome, paved strips signal to pedestrians to use caution when approaching the platform.
The pre-warning tiles are generally black in color, come in various dimensions, and provide the same slip resistance value as the tactile domes.

Commonly used at bus and streetcar stops, straight edge tiles make the transition from street to sidewalk much more fluid. The tiles are installed in the sidewalk behind the curb line and will extend to the length of the boarding area of the bus or streetcar.

TekWay manufactures detectable warning domes for both platform edge and recessed designs. Both the straight edge tile and the popular bull-nose edge are available in staggered and in-line patterns. 
Designed for platform edge installations, the bull-nose tile minimizes the impact of chipping and breakage caused by heavy-wheeled carts and mobility devices. The rounded edge provides and enhances a secure ledge from the platform to the public transportation vehicle.

When pedestrians and bicyclists meet in congested cities or university intersections, their different speeds and momentums create a potential safety hazard for everyone involved. Cyclist Warning Rumblers offer an effective way to enhance the safety of people who bike and walk while also reducing crashes. As cyclists approach a pedestrian crossing or intersection, they will run over these rumblers, giving them a simple tactile warning to slow down and be aware of pedestrians or cars—similar to speed bumps for cars.

The optimal solution for separating sidewalk-level bicycle and pedestrian pathways in dense urban areas like  universities and city centers. They are intended to be used in areas such as city centers, parks, and universities or any locations where the two paths would be adjacent on the same level. Those with no or low vision are able to physically detect the Delineator Tiles and avoid crossing them while bicyclists can safely see and feel the boundary between the pedestrian and bicycle path.
