How can Urban Goods Movements be Surveyed in a Megacity? The Case of the Paris Region

This paper describes the survey method built to carry out the UGM survey in the Paris region. The size of the city, around 12 million inhabitants spread over a territory of 12,000 km2, and the cost constraints led us to design a specific sampling methodology based on a typology of the 1,300 Parisian municipalities. Thus it was possible to capture all the movements and main logistical behavior of the city by surveying only 1,200 establishments.
