Description: Platform stops improve this situation through the provision of passengers platforms raised to the level of low floor trams next to the tracks in the middle of the road. Passengers access the platform using signal controlled pedestrian crossings.On roads with lower traffic levels, platforms are accessed via zebra crossings at the ends of the platform.

Prior Condition:  safety zone tram stops

Category: Transit
