Veranderingen in de verkeersspits tussen 1978 en 1988

During the period from 1978 to 1988 the volume of traffic has clearly increased. This increase of mobility causes traffic delay during peak hours. the peak concept is a central item in models for traffic prediction and transport policy. The number of trips has increased during peak hours by 30%. That produces a longer period with a high level of trips. These findings are a stimulus to reconsider the peak concept.
