Guidelines For Quality Management Of Traffic Signal Systems In Germany

This paper outlines guidelines for quality management of traffic signal systems in Germany. The authors contend that, due to restricted resources, operators of traffic signal systems rarely apply an extensive quality management system but merely react to obvious deficiencies, especially when it comes to apparent problems in traffic flow. Other deficiencies that are less apparent but have also a negative impact for road users are not addressed and often even not revealed. The authors describe a project undertaken to develop a practical, efficient, cost-effective and resource-saving quality management approach for traffic signal systems that meets the requirement of the operators. A questionnaire was sent to 244 operators of traffic signal systems in Germany; 97 responses were evaluated. Based on the responses, a prototype was developed and presented to staff members of about 60 traffic management centers, where it was received enthusiastically. The guidelines have three primary components: analysis of road safety; analysis of traffic quality in networks; and analysis of traffic quality at critical signal controlled intersections. In addition to these three main parts, the prototype also covers information management, a complaint management component, and a focus on the maintenance of traffic signal systems. A system for re-evaluation after implementation is also described.
