NDW is a partner in the European project SOCRATES2.0. The public and private partners in this project want to gain insight into how they can best organize the cooperation and exchange data and whether this cooperation actually leads to improved services for road users. SOCRATES 2.0 is executing pilots in four European cities: Amsterdam, Antwerp, Copenhagen and Munich.

The so-called “cooperation framework” for cooperation in the traffic management and information chain, describes various cooperation models and defines intermediate roles to facilitate public-private partnerships. Public and private parties all have their own traffic data and base their information and navigation services on it. In the SOCRATES2.0 project, these parties work together by sharing their data and coordinating the navigation recommendations. The aim is to improve and renew traffic management and information services. In this way they want to further improve traffic flow and safety. NDW facilitates this collaboration.

NDW is involved in the pilot in Amsterdam and the 4 use cases that are being tested there are: traffic information and route advice with the aim of network optimization, smart route advice to event locations, information and advice during road works and environmental zones. Except for the use case roadworks, NDW will fulfill a network monitor role. The network monitor collects data from road authorities and private data providers and determines the common current (and if possible predicted) status for a predefined network. In this process, the network monitor can perform services such as: data processing, merger and completion of various public-private sources and quality assessment. The network monitor distributes the common network status to the network manager, where it is determined on the basis of agreed KPIs whether measures should be taken.

The road authorities will participate in a strategy table for both the use case network optimization and smart route advice at events. This is the place to establish and monitor (and where necessary revise) strategic cooperation (joint and coordinated approach) between public and private parties. Both individual and common goals are identified and translated into measurable KPIs.

Prediction of traffic jams by sharing data

Road authorities and market parties share their available information and merge it in order to obtain a complete and accurate picture of the current traffic situation. This data from various sources is collected and processed by NDW. In addition, real-time traffic information is combined with data from the past to calculate the probability of a traffic jam in the next 15 to 30 minutes. NDW is responsible for compiling and distributing both current and predicted traffic status based on different data flows from different partners. The network manager uses both data streams to propose traffic measures. These are processed by service providers (public and private) in their traffic information and navigation advice.

A trial has recently started to test this new service and the collaboration. In order to improve the traffic around Amsterdam, motorists are offered an alternative route in good time in the event of impending traffic jams via the navigation system or navigation app. Traffic will then be better spread over the entire road network, resulting in fewer traffic jams.

Test users
Road users who regularly drive in the Amsterdam region can register as a test user at After registration they receive an instruction from the navigation service provider what to do or install on their phone in order to test the new service. The new service is offered by Be-Mobile (Flitsmeister), TomTom and BrandMKRS (Livecrowd Mobility). Test users receive a number of short surveys asking about their experiences with the improved navigation services. The trial runs until march 2021.
