| Abstrait: |
Because of the large traffic-jam problem in the Netherlands the road capacity had to be increased on a lot of motorways. In the last decade the Dutch Ministry of Public Works started the ZSM program (Dutch abbreviation for Visible, Smart, and Measurable) as a part of the widening of main national highways. In this program, for the most routes of the traffic jam top 50, it was investigated if the road capacity can be increased fast by creating rush-hour lanes on hard-shoulders. As the road capacity increases, the traffic volume increases too. Therefore regulations on allowable noise and air pollution are observed and measures such as sound barriers and a noise reducing asphalt layer have to be taken. The widening of the highways on structures leads to an increase in loading with regard to the original design. Therefore many existing structures in these motorways are in-depth structural assessed in the ZSM program. In the paper the processes and issues around these projects are presented. |
