UITP SORT & E-SORT brochures
SORT aims to provide the bus sector with a standardised means of comparing the energy consumption of different buses
The SORT project (‘Standardised On-Road Test cycles’) is an initiative of the UITP Bus Committee and a result of cooperation between VDV, public transport operators and the leading European manufacturers of vehicles and transmissions. Its main aim is to design reproducible test cycles for on-road tests of buses in order to measure their fuel consumption.
To meet the changing needs of the sector, SORT has in 2017 expanded its scope to include electric buses. The newly branded ‘E-SORT’ has the aim to measure, in an accurate and reproducible way, the traction energy consumption and to obtain information on the Zero Emissions range of a bus.
This methodology allows bus operators to access comparative data regarding traction energy consumption (either fuel, gas or electricity) and information on the optimal daily range for electric buses. The test protocol applies to two types of buses: full electric buses and hybrid buses that can be externally re-charged (plug-in hybrid electric bus).
