Abstract
One of the objectives of the Atena project was the definition of
methods for the predictive evaluation of the environmental impact
of different types of vehicles used in an urban scenario. The
target is to obtain a methodology that allows the decision maker to
verify in simulation the effects of possible measures like the law
enforcement to the access restrictions or vehicle fleet
composition. The main obstacle is the realization and managing of
real driving cycles in order to overtake the limits derived from
the utilization of typical cycles (i.e., ECE + EUDC) or the simple
consideration of average speed.
The starting point is a digital representation of the urban
network where all the roads are represented with one or more arcs
and for all these arcs are available an estimation of the traffic
variables like the vehicle flow (vehicles per hour) or the average
speed (kph). Every arc is described in terms of traffic parameters
like the type of road (i.e., highway, district road). The results
presented in this work will be a contribution for the definition of
a methodology able to describe the emissions of vehicles fleets in
terms of traffic and vehicle parameters.
