The Digital Road Authority combines different types of traffic data in order to provide the residents of IJburg with personalised travel advice. Residents receive advice through an app, based on appointments in their phone’s calendar, their destination and the current situation at the traffic lights. The Digital Road Authority is not only in contact with departing travellers, but also with the traffic lights. It divides personal ‘travel slots’ based on current and expected traffic density. In case of (expexted) high traffic density, the Digital Road Authority can also increase the ‘green time’ at the traffic lights to improve traffic circulation.
