Traffic load model for the inner city of Amsterdam

In historic urban areas, heavy transport vehicle weight limits are more strict than on main roads. In Amster- dam yearly permits are needed for vehicles over 7.5 tons, and special permits for those over 30 tons. Current traffic load models for bridges use traffic data from highways. This leads to conservative safety assessments and consequently, possible unnecessary repair or reconstruction costs. Determining a traffic load model for the assessment of bridges, specifically developed for the inner city is challenging because of the limited avail- able traffic data. In this paper, Weigh-In-Motion (WIM-ROAD) data is combined with camera data to create a representative traffic load database for the inner city of Amsterdam. Based on this location-specific data- base, traffic load effects are simulated, and reliability analyses are conducted to align with load models given in EN 1991-2 [1] and the Dutch standard for the assessment of existing structures NEN 8700 [2].
