THE ASSESSMENT OF ECONOMIC BENEFITS OF DYNAMIC TRAFFIC MANAGEMENT

A well known phenomenon in traffic management is: that after an improvement in traffic conditions, the traffic volumes increase and as a consequence, the traffic conditions deteriorate again to a level close to the situation before the improvement. The reasons for the increase in traffic flow are a combination of: (1) rerouting; (2) change of departure time; (3) trip length modifications; (4) suppressed travel demand; (5) induced travel demand; (6) modal shift; and (7) the growth of population or economic situation. The first 6 reasons have a direct relation with the improvement of the traffic conditions while the 7th reason is only indirect. The growth of the traffic volume due to improvements in capacity or better utilization of existing capacity make the investments in most conditions still worthwhile, even if the net reductions of travel times are small or zero. However, in some conditions there is no net profit. Apart from the impact of improved travel conditions on travel behavior of persons, similar effects can be observed for freight transport.
