The term driver assistance systems in the chapter title shall be understood to include vehicle automation. This chapter starts with a homogeneous and consistent classification and nomenclature of all kinds of driver assistance systems known and under discussion today (including vehicle automation). It thereby builds upon familiar classification schemes by the German Federal Highway Research Institute (BASt) and the standardization body SAE international. Detailed evaluation of the German legal situation for driver assistance systems and vehicle automation is provided in the following Sect. 2. In Sect. 3, an overview is given on the legal system in the US to reveal aspects relevant for vehicle automation. This is intended as initial information for those not acquainted to the US legal system which has been the first to regulate automation in several federal states. Finally, in Sect. 4, the current rating scheme of the European New Car Assessment Programme (EuroNCAP) is presented in comparison to legal instruments. The model of a consumer protection based approach proves to be a flexible instrument with great advantages in promoting new technologies. Technical vehicle regulations on the other hand rule minimum requirements. Both approaches are needed to achieve maximum vehicle safety.
Im Rahmen einer durch die Bundesanstalt für Straßenwesen (BASt} initiierten Studie wurde das geothermische Potenzial des anfallenden Bergwassers für 15 Portale von deutschen Straßentunneln abgeschätzt und mögliche Konzepte zur Nutzung der hydrogeothermischen Energie aufgezeigt. Das Institut für Geotechnik der Universität Stuttgart (IGS} hat im Anschluss für drei dieser Portale die Untersuchungen zum geothermischen Potenzial fortgeführt sowie Wärmenutzungskonzepte aufgestellt und detailliert geplant. Als Ergebnis liegt die Entwurfsplanung für eine geothermische Anlage am Nordportal des Grenztunnels Füssen vor. Es wird ein Überblick über die durchgeführten Untersuchungen, den Prozess der Portalauswahl und die relevanten Wärmenutzungen gegeben.
In Germany road tunnels on major roads which are longer than 400 m have to be monitored permanently. For that purpose the tunnels are equipped with a multitude of monitoring and detection systems whose data and messages are transmitted to tunnel control centres. Due to the higher traffic density, the increasing number of tunnels to be monitored and road users" demand of higher safety and security levels, the strains on operating staff of tunnel control centres have continuously been growing. Therefore, innovative approaches have been developed in two recent German research projects: RETISS " Real Time Security Management System, and ESIMAS " Real-time Safety Management System for road Tunnels. Both systems are designed to allow faster and more efficient reaction of tunnel operators in order to maintain the capacity and availability of transport infrastructures but also to improve the safety and security of road users.
