A pedestrian crosswalk is typically coded at an intersection using links that match the width and location of the crosswalk in the field that cross over the leg of the intersection. It is best practice to use a different display type for pedestrian crosswalk links to show that these are separate from the vehicle network links. Signal heads and detectors are used on the pedestrian crosswalk links for pedestrian movements controlled by a pedestrian signal. Conflict areas are coded between vehicle and pedestrian links. It is best practice to give priority to pedestrians by coding the green conflict area for pedestrian links and red for the overlapping vehicle links. However, conflict areas can lead to gridlock in certain situations, such as urban areas and areas with congestion. For those areas, it is recommended to use priority rules to avoid the network from gridlocking.
