Influencing traffic

Mobility is part of our society. Each day, millions of people travel to and from work, shops, sports clubs or family. Goods are transported between locations to end up in a store or at the end-user. When too many people or goods want to use the same infrastructure at the same time, a bottleneck develops. After all, each infrastructure has a maximum capacity. Bottlenecks can be solved with infrastructural adjustments and extensions. However, this requires large investments and takes time. Therefore, the significance of alternative ways to solve bottlenecks increases. One of those alternatives is traffic management.

Improved utilization of the scarcely available infrastructure is an important way to meet the mobility growth on a network that has limits to its expansion. By providing proper information and by implementing traffic management measures, the amount of traffic can be spread in a better way over time, modalities and available capacity. An integrated approach to traffic issues delivers the best results.

The road networks of decentralised road authorities (like municipalities and Provinces) have especially many traffic management measures in place, equipped for traffic managing on a local level. They are mainly related to traffic lights. In addition, an increasing number of information and guidance systems – like Parking and Route Guidance Systems – are being implemented. Because DTV Consultants is a research and consultancy firm that mostly works for municipalities and Provinces, we have an objective and broad view to the possibilities and impossibilities of traffic management and much experience in this field.

Traffic management measures can be deployed in various ways. They are well-suited to react in pre-determined ways to local traffic flow problems. To also make more efficient use of the available capacity on a route or a network level, local measures should be implemented so that they cooperate with other systems in a coordinated way. Traffic can for example be spread better or be re-directed with help of Variable Message Signs (VMS). In case of congestion, the specific traffic surplus can be allowed green lights longer or more often.

In addition to a vision on how to deal with traffic and the road network, new traffic management measures are required, as well as central software and adjustments to existing instruments. Dependent on the level of regional cooperation to keep traffic flowing properly, links need to be made between local, regional and central traffic control systems. This way, traffic flows on other roads will not unintentionally be influenced in a negative way. In some regions, cooperation on various governmental levels is already so concrete, that a regional traffic control centre coordinates the use of local measures, thereby facilitating complete traffic flows (and not just separate parts of it). In these cases, the road users and not the (administrative) boundaries of road authorities form the starting point. DTV Consultants has much expertise in traffic light systems and how to coordinate or influence them from other traffic management systems or central traffic light control systems.

Additional services that we can provide are to:
• Write (functional) concepts and specifications for Parking Guide Systems (PGS), selective access or VMS, tender out such projects and realize them together with the client;
• Monitor the conversion of existing solitary traffic light installations to installations that can be influenced remotely, including the connection to fast communication/internet connections and to write alternative traffic control programs;
• Use policy scenarios to draw up implementation plans with concrete steps on how to realize and implement measures;
• Make specifications for modern central applications to replace outdated ones;
• Analyze existing situations at road authorities and write adjustment plans to improve the situation;
• Help realize systems and organizational structures for a traffic control centre;
• Give a second opinion with regard to products, plans, designs or other (contractual) documents that need to be tested and / or approved.
