Creating OD matrix using cordon survey: case study – City of Varaždin

Abstract

Nowadays, cities have a problem with transport planning. Transport planning is a time-consuming process and a data-eating process. For the purpose of transport planning, it is necessary to collect up-to-date data, not only transport data (number of vehicles, bus lines, passengers carried, etc.), but also demographic data, urbanization data and economic data. The most frequently changed data are those from transport, which means it is necessary to implement a strategic process to collect these data. This process is not only time-consuming but also money-consuming. Without transport data it is not possible to make smart mobility plans for citizens. The most important function of transport data collection is building of an Origin-Destination Matrix (OD Matrix). There is a wide range of methods for collecting and building of this OD Matrix. This paper explains the building of OD Matrix using innovated cordon survey in road transport. Cordon survey is a field method to collect information about travel preferences of road drivers. Cordon survey has been performed on strategic points entering the City of Varaždin. The cordon survey was carried out during two-hour intervals in early morning, late morning and afternoon.
