Bioethanol buses are accepted by drivers, passengers and mechanics. Drivers and mechanics see improved working conditions and reduced emissions as key benefits. Passengers are satisfied with the performance of the vehicles and view reduced emissions as an important factor.
Drivers and mechanics praise reduced emissions
A majority of drivers in Italy, Sweden, Spain and Brazil were positive to bioethanol buses in a survey performed within BEST. Many praised bioethanol buses for reducing pollution, exhaust emissions and odour, and improving comfort for drivers. However, reduced acceleration and speed were cited as major problems.
Mechanics in Sweden, Spain and Brazil also responded to a questionnaire on bioethanol buses. Interestingly, 53 % of these were positive to the technology before introduction, but over time this number rose to 63 %. As with the drivers, mechanics were most enthusiastic about the reduced emissions offered by bioethanol buses but most negative about reduced acceleration.
Passenger surveys were conducted in Madrid and Nanyang. Passengers perceived no obvious difference in the quality of service compared to other types of buses, but were impressed by the decrease in pollution and smoother running of bioethanol buses. The odour aspect was found to be both negative and positive. Noise during operation and (not related to the buses) timetables and delays were cited as major problems.
