Challenge / Goal

  • Problem: During a public survey conducted in Duisburg it was found out that waiting time at queues was one of the major issues at civic amenity sites, discouraging citizens to bring their recyclable materials for proper treatment.
  • Goal 1: Through simple and transparent information, enable citizens to plan their trip to the amenity site, during the most convenient opportunity, optimizing traffic conditions and waiting time.
  • Goal 2: Enable citizens to choose the best available site, with the lowest occupancy and waiting time in order to avoid waiting peaks.


Over-head sensors have been deployed to digitize and evaluate the whole site occupancy. In addition, an algorithm that calculates waiting time dependent on number of cars in queue and number of cars on the site have been created and applied. The generated information is available on the website of WB Duisburg and their own mobile app, with which citizens can check for the best opportunity and plan their trip to the most accessible site.

Citizen participation

During a survey organized by the municipality, citizens brought up the problem. It has been demanded an information service where they would get to know about this service via a web link.
