The high density of commercial freight transport on motorways makes it difficult for truck drivers to find safe parking places especially for longer rest periods during the night. Even though expansions have been made to satisfy the demand in Germany, overcrowding and dangerous situations still occur as a result of vehicles parking on the entrance and exit roads of rest areas. In 2005 a control procedure called "Convoy Parking" was installed at the rest area Montabaur on the A3 motorway in Germany. Convoy Parking is subject to a patent (EP 1 408 455 B1, 2007). Convoy Parking requires all drivers entering their departure time at a terminal in front of a barrier. Subsequently, on the basis of the input data, the automatically detected vehicle length and the actual situation at the rest area, a free parking row is assigned and trucks can be parked sorted. The German Federal Highway Research Institute (BASt) developed a new control procedure called "Intelligent Controlled Compact Parking" (hereafter referred to as "Compact Parking" for short) to achieve that trucks are parking in a compact way, side by side and without a driving lane between trucks. Convoy Parking and Compact Parking have a very different control procedure and appearance. While Convoy Parking assigns a parking row to the driver, Compact Parking deliberately leaves the choice of the parking row to the drivers themselves. Drivers do not have to disclose their departure time to any system and they are not stopped by any barrier because Compact Parking offers a wide range of departure times on variable message signs. Drivers ought to use the parking row where their intended departure time is offered. With the innovative system Compact Parking the capacity of an existing rest area can be quickly increased without enlarging the area. This also avoids long-term planning approval procedures and is friendly to the environment. Besides, the safety for all users of the rest area can be improved by reducing illegal parking. Compact Parking is supported by the German Federal Ministry of Transport and Digital Infrastructure (BMVI). The first installation of Compact Parking is under construction at the rest area Jura-West on the A3 motorway (Northern Bavaria). The Autobahndirektion Nordbayern (Motorway Directorate for Northern Bavaria) is the central agency to plan, build and run the motorways in Northern Bavaria and got the approval of the BMVI to realize the pilot project. BASt accompanies the pilot project and leads the implementation of the control procedure. The opening is scheduled for summer 2015.
Efficient and widely available transport infrastructure is one of the most important prerequisites for sustainable economic development to meet the demand for mobility. In this context, being able to manage traffic growth forecasts is of particular importance. In Germany, current forecasts indicate a 40% increase in rail and road transport in the country. However, about 60% of bridges (as measured by bridge area) on the national German highway system that are suitable for freight transport were built before 1985. In other transport sectors as well, aging infrastructure is one of the key challenges for the availability and the resilience of European transport infrastructure. Many bridges in the national German highway system are already at their load-bearing limit. Furthermore, required maintenance measures have not been adequately carried out in the past due to limited budgets, leading to overall bridge deterioration. Further challenges for owners and operators of transport infrastructure result from the effects of climate change, associated climate extremes, natural catastrophes, and possible criminal and terrorist threats. To ensure that future infrastructure challenges can be successfully addressed, strategies and solutions must be developed and implemented in a timely manner to enable holistic and sustainable life-cycle management. The concepts of Resilience Management as well as Resilience Engineering are essential building blocks in this process. Resilience is the ability to survive in the face of a complex, uncertain, and ever-changing future. It is a way of thinking about both short-term cycles and long-term trends. Using this concept, owners and operators can reduce the risk of disruption in the face of shocks and stresses. Resilience requires cyclical, proactive, and holistic risk management practices.
