In 2012, the Amsterdam Metropolitan Area demonstrated at Intertraffic that its network management systems (NMS) could be connected with each other. This means that Rijkswaterstaat, the province of Noord-Holland and the City of Amsterdam are now able to exchange and deploy scenarios. This first version of DVM-Exchange (DVMX) has been developed further, with many new functionalities being added.
The launch of version 2.5 means that object statuses can now also be exchanged. With the addition of this layer, it has become possible to exchange the state and status of linked-up roadside equipment between the connected systems. In addition to activating scenarios that the different participating systems suggest, it is also possible to generate comprehensive surveys. Overviews, for instance, that combine the currently displayed image on the DRIPs and the statuses (active, flash, turned off) of other road managers’ connected traffic control systems/ramp meters. This produces a ‘Common Operational Picture’ that enables road managers to create a complete picture of the DTM measures in any given area.
Horizontal and vertical connections
In addition to this horizontal application (which allows road managers access to each other’s systems), DVM-Exchange 2.5 can also ‘connect vertically’. These vertical connections are necessary to obtain a complete picture in cases where several DTM subsystems originate from different suppliers, for instance a traffic control center, a DRIP server and a PRIS. An overarching network management system can be placed ‘on top’ of this to generate a complete picture of all the roadside equipment.
DVM-Exchange has already found possibilities for application outside the Metropolitan Area. Technolution is rolling out DVM-Exchange via its MobiMaestro platform, which has been implemented by the municipalities of Rotterdam, Deventer and Nijmegen, among others. Our customers in these cities are now effortlessly connecting to applications of their fellow road managers in the vicinity.
