Autonomous shuttles operate in mixed traffic, using existing infrastructures. The vehicles are as fast as the slowest other road user, restricting the hourly capacity that can be provided. As there are no specific civil works, the low capital cost ensure a financially viable transit is still possible.
Automated Transit Systems
ATN systems operate on a network of dedicated guideways to allow direct origin to destination travel. The direct connections optimize the passenger service level as well as the fleet capacity, ensuring a strong operational business case.
Automated People Movers: segragated infrastructure with grade separated crossings for high capacities
APM systems feature autonomous vehicles on a segragated, typically elevated guideway allowing for a high capacity through grade separated intersections. The additonal capital costs for the infrastructure are offset by the higher service level and the resulting ridership.
