This report describes how the concept of `quality levels' has been elaborated for use in reference maps. Reference maps will be applied in operational Dynamic Traffic Management (DTM) in the Alkmaar region (Netherlands). They provide a means of expressing the desired quality of traffic flows over a network so that it can be compared to the actual traffic conditions. Some key issues in the Dutch National Architecture for Traffic Management (AVB) and the Traffic Control Loop have been put into practice for the first time in this project: (1) splitting the network according to the building blocks identified in an infrastructure layer model; (2) identification of a suitable criterion expressing the quality of traffic flow for each of the layers of the infrastructure model; (3) quantification of the desired quality of traffic flow, expressed in a reference map; and (4) consistency check of the monitoring infrastructure (as envisaged in the monitoring plan) with the quality criteria: is the monitoring equipment and location sufficient to provide an actual overview of prevailing traffic conditions? The work reported in the report is an important contribution to AVB for two reasons. Not only is it the first time that AVB was elaborated to such a concrete level, the rational behind AVB was also applied here to a mixed urban and inter-urban network, whereas AVB was originally intended for the highway network ((inter-urban) only.
