On those tricky mixed use arterial roads there is often a need to install a midblock pedestrian operated set of traffic signals. These can aid to balance traffic flow and pedestrian crossing opportunity. But these are almost always installed without any traffic calming. These present a point of heightened pedestrian risk and should be fitted with either raised safety platforms or speed calming on the approach.
Some common reasons people push back on a raised safety platform are busses and drainage. While properly designed raised platforms can account for these elements, if they seem insurmountable perhaps consider speed cushions on the approach (see photo above).
