Accessibility - Sound-enhanced pedestrian crossings

State of play of pedestrian crossings for PRM (pedestrian crossings and lowered sidewalks) according to the regulatory technical requirements related to accessibility (width of passage, percentage of slope, wake-up devices, obstacles encountered, sound lights ...). Each crossing is affected by a level of accessibility for the motor impaired, visual, and any disability. The dot layer is generated by a polyline input layer that represents the layout of pedestrian crossings or pedestrian crossings, digitized by recognition of 2014 aerial photography and field observations. Each point is located at the centroid of a line. Attributes were provided through field observations and surveys. The levels of disability were determined at the discretion of the road technician according to the characteristics noted.
