15.4.6 Number of Vehicles Completing Simulation

As described in the preceding two sections, it is important to dene,

a priori, how a given travel time or delay measure will be counted (i.e.,

when a vehicle exits or enters a link, or based on some weighted aver-

age). It is equally important, however, to make sure that any comparisons

made between competing scenarios are valid. As an example, simulation

1 might have better average delay values than simulation 2. However, if

simulation 2 has a greater throughput (i.e., more vehicles arrive at their

destination), then it may not be clear which is the more desi ...
