Abstract
The Public Transportation System is now rediscovering the use of trams due to
ever increasing pollution problems. The entire system transports from 2000 to
15000 p/hd, and uses either the right of way (ROW) or the light rail transit
(LRT). Nevertheless a new generation of articulated electric trolley buses (ETB)
are becoming an attractive option. The ETB is "bimodal", or rather, it has a
double traction energy supply. Its engine-electric generator unit allows it to
disconnect from the Overhead Catenary System (OCS) and continue operating as
before. This paper compares an ETB transportation system, which uses vehicles
holding 155 p, with the currently tram system used in Rome, which uses vehicles
holding 180 or 260 p. Based on the same passenger-flow, this compar
