Protect both on-scene responders and the traveling public Reduce delays and associated impacts on travelers Reduce the possibility of secondary incidents Ensure that response resources tied up at incidents are put back into service quickly Top-of-the-line equipment such as the rotator pictured here enables towing and recovery companies to clear roads in minutes instead of hours.

7 Heavy Occupical Vehicle Tolling Lane
a high-occupancy vehicle lane (or HOV lane) is a lane for vehicles with a driver and one or more passengers Some HOV lanes are built on totally separate roadways from their corresponding general use lanes; are constructed on parallel roads separated by a concrete barrier, are built on grade-separated (i.e. elevated or underground) roadways. One example is the Harbor Freeway in Los Angeles, California, where four HOV lanes travel on the upper deck of the freeway. This type of construction is said to maintain optimal efficiency by keeping general use traffic from merging back and forth into the HOV lanes, and by maximizing space on the main roadway for general use traffic. Additionally, major interchanges on such routes are often equipped with HOV-only ramps, which minimizes haphazard cross-freeway merging. Four high-occupancy vehicle lanes are elevated over general-use lanes on the Harbor Freeway in Los Angeles, CA Some cities that use separated HOV lanes make them reversible; i.e. usable only by inbound traffic during the morning rush and usable only by outbound traffic during the evening rush.

8 Temporary emergency lane opening
Emergency lanes increase the security on motorways Using the emergency lane means a higher security risk (about 25%) but increases also the road capacity with marginal costs Variable message signs variable message signs have to be used for lane allocation because of: shift in direction lane allocation on intersections lane allocation before and after a tunnel temporary emergency lane opening complete blocking of a tunnel Source: Hinweise zu variablen Fahrstreifenzuteilungen – Anwendungsbeispiele und Einsatzmöglichkeiten, Ausgabe 2003, FGSV e.V.

11 Bauteiltemperierung: Energie liegt auf der Straße
Fahrbahnabsorber: mit Sommerwärme gegen Winterglatteis Ziele: höhere Sicherheit, weniger Schäden an Belag u. Bauwerken Kombination von oberflächennaher Geothermie mit Massivabsorber. Nutzung des angrenzenden Erdreichs für saisonale Speicherung Ziele: Verminderung der Temperaturschwankungen => Winter: weniger Fortschäden, kein Blitzeis, weniger Schäden an Fahrbahn (und Karosserien nur relevant sofern irgendwann flächendeckend verfügbar) Sommer: bei Asphalt weniger Spurrillenbildung Energetisch: im von der Fa. Polydynamics umgestzten BVH wurden folgende Werte ermittelt: Heizleistung 260 W/m², Kühlleistung 100 W/m² Quelle: Fraunhofer Institut Bauphysik
