Following general considerations on the present state of commuter traffic in the downtown sections of the cities, the specifications of an highly efficacious and efficient vehicle for individual transportation are analyzed.
A two-wheeler vehicle appears very attractive when pollution and noise are overcome.
A new formula of vehicle is so presented looking for a minimum optimun solution to the problem.
The basic feature consists in an hybrid propulsion system, namely: internal combustion engine with catalytic muffler for downtown approach and an accumulator powered electric motor during restricted area trips.
After the presentation of the experimental results, some considerations on utilization coefficient as well as energy use efficiency, in comparison with other modes of transportation, are presented.
