What Is Required to Guarantee Data Quality for Regional Traffic Management

VERDER, a partnership of different governmental organizations in the Middle Netherlands, initiated different projects for regional traffic management to better use existing road capacity and safeguard mobility in the Middle Netherlands. This active form of traffic management requires traffic data with a certain quality level, although this is not taken into account in current plans. An organization plan to guarantee data quality for regional traffic management, based on various literature and expert interviews, was created and validated with experts. The plan contains a chain manager responsible for managing data quality through the information chains of regional traffic management and four different data management steps: define, measure, analyse and improve. The validation revealed that this plan brings substantial improvement on current practice.
