For midblock crossings to be accessible to people with visual impairments, they need to be detectable.At midblock crossings, pedestrians with visual impairments do not have the sound of parallel traffic available to identify a midblock crossing opportunity. What are the requirements for curb ramps used at intersections? All parking spaces and access aisles must be marked with the international accessibility symbol and have firm, stable and slip resistant pavement surfaces. However, if the cut-through is too wide, people with visual impairments might not detect the presence of a median or island. The survey revealed that, while 94 percent of builders and developers had to obtain building permits, only 36 percent were required to undergo plan checking, and only 19 percent were required to design sidewalks more than 1.220 m (48 in) wide (NAHB, 1995). FHWA studies are currently being conducted to determine if these measures provide safer crossing for pedestrians. Figure 4-39: Cut-through corner island and center median (based on OR DOT, 1995). The most accessible were relatively large and could be activated with little force. Our team leads in manufacturing, customer service, technical support, and distribution, with over 1,500 distribution locations across North, Central, and South America. For example, the street name signs on many large arterials are hung in the center of the intersection. This problem is compounded by the fact that "pedestrians may 'feel safer' within a marked crosswalk and expect motorists to act more cautiously" (Institute of Transportation Engineers, Technical Council Committee 5A-5, 1998). However, when crossing times accommodate only people who walk at or above the average walking speed, intersections become unusable for people who walk at a slower pace.To accommodate the slower walking speeds of some pedestrians, transportation agencies should consider extending their pedestrian signal cycles. Figure 4-41: Two horizontal lines are the most common crosswalk markings. Inaccessible grade-separated crossings should not be constructed.

Maintaining sidewalk elements in good condition is an essential part of providing access to public rights-of-way. 1 Florida directs people to the ADA for maximum grade requirements. According to the AASHTO Green Book, a cross-slope between 1.5 to 2.0 percent provides effective drainage on paved surfaces in most weather conditions (AASHTO, 1995). 1The lower the maximum speed permitted on the road, the steeper the grade is permitted to be.
