|GP: Clean Public Transport Fleet in Rome: Trolleys and EURO 4 Buses - Italy|
With the support of MIRACLES a programme was designed to speed up the renewal of the PT fleet. Between 2002-2003, 1,107 EURO 3 buses were purchased, 300 of which are equipped with the CRT system, to achieve EURO 4 standards. Furthermore 30 new generation, bi-modal trolley buses have been introduced, following tests carried out by ATAC in Hungary.
Objectives/ Innovative Aspects
* to extend the electric traction modes: conventional systems and innovative battery-propelled vehicles
Rome has a surface PT network of over 3,500 km, served by 339 lines and operated with almost 2,500 buses. The LTZ (Limited Traffic Zone) covers a surface of 5.2 km2, in the 1,300 km2 of the whole Municipality. The LTZ, which incorporates the main cultural heritage area of Rome, is at the core of the municipality policy to reduce traffic pollution.
With the support of MIRACLES an important plan has been designed and implemented by ATAC (Rome’s PT Agency). At the beginning of the Project the traditional bus fleet mainly consisted of old and polluting buses (EURO 0), which were not compliant with the European emission standards in force. A programme was designed to speed up the renewal of this fleet. Between 2002-2003, 1,107 EURO 3 buses were purchased. Within this, it was specified that 300 buses (200 urban and 100 sub-urban) should be MERCEDES CITARO models, with better emission levels than EURO 3 standards. These buses are in fact equipped with the Continuous Regenerating Trap (CRT) system, which reduces PM 10, the most important traffic pollutant in Rome. The CRT system significantly reduces overall emission levels from buses, allowing them to achieve EURO 4 standards. Thirty “new generation”, bi-modal trolley buses have been introduced, following tests carried out by ATAC in Hungary. The trolley buses have been delivered to the new depot (Montesacro) in Rome. Trials of the trolley buses and driver training began during autumn 2004.
The clean bus fleet in Rome has been increased. The aim was to replace at least 25% of the PT fleet with EURO 3 Standard clean vehicles and electrical vehicles. In a fleet of 2,466 buses operating at present, 1,107 are EURO 3 and are operating on PT lines within the Laboratory Area.
