Comparativ example operating cost :
Distance : 180 km
Livada Poştei - Poiana Braşov) Route
Conditions :
 aproximatively the same capacity
 no clima and lighting
Electric bus - Cost 0.480 lei km
Diesel bus - Cost 2,02 lei km

7. EVENTS
During testing we were organized more events show that have made
demonstration flights for professionals, children, students and representatives of
local institutions.
During these events representatives Brasov Autonomous Transport provided
information about the operating principle of the bus, technical details and
importance of mobility.

9. CONCLUSIONS
 Comparing with Diesel buses whic operate the same routes carried these
highlights a cost per km at least three times lower
 Maximum distance during the full load was 268 km with the remaining
batterry capacity of 18%
 During operation, the interior noise charge higher than the trolley
 The experimemental periong being short can not make estimates of the costs
of maintanance, batteries and equipment behaviour over time
 To obtain more relevant results about running it takes a longer operating
