Highway AG-64 is located in Galicia, northwestern Spain, running between cities of Ferrol (La Coruña) and Vilalba (Lugo) with a length of 64 km, connecting Ferrol-Terra area to highway A-8, making possible both the access to A-6 highway (Madrid-La Coruña) and to Cantabric Highway which runs parallel to the north coast of Spain.
It is also remarkable that AG-64 Highway allows the connection to Ferrol Harbor, one of the most important in Spain (Shipping Yard and Container Terminal), as well as to Thermal Power Plant As Pontes, becoming the link of these two strategical points related to energy in particular and to economy in general.
Within the highway there are several key points regarding traffic management in bad weather conditions, situations which impact directly not only in road safety but also causing abnormal congestions.
The volume of registered traffic in a day reaches 12,000 veh/day with a peak of 1,000 vehicles per hour. HGV percentage is really important, 17% average, mainly due to access to Ferrol Harbour.
Due to the importance of improving road management between A-6 and A-8 highways and the requirement of reducing potential traffic situations of risk, deployment of new Intelligent Transport Systems in AG-64 highway was defined as one of the main projects in DGT traffic management strategy.
It must be mentioned that with this deployment the close of “communications ring” on the Traffic Control Center in Northwest of Spain (located in La Coruña) was closed and achieved.
The Objectives established were:
- Enhancement of A-6 and A-8 connection.
- Improvement of access to Ferrol harbour.
- Reduction of abnormal congestion due to bad weather conditions: 15% decrease of delay-hours.
- 20 % reduction of registered accidents. It must be noted that 24 % of accidents area related to rear collision between a HGV and a light vehicle (factor: speed disparity)
The project includes deployment of weather and traffic monitoring systems, traffic management systems including mean-speed controls and road safety variable message equipment to avoid rear-end collisions into heavy vehicles.
Main equipment is listed below:
- Variable Message Sign: 11
- Communications Stations (ERU): 11
- Traffic Data Capture Stations (ETD): 11
- Weather Stations: 3
- CCTV systems: 10
- LPR units: 4
The deployment of all systems, which began in 2013, ended up successfully in December 2014. As a result of the deployment of all this equipment the amount of accidents registered until the 30th June 2015 has decreased in 25% comparing to data of 2014.
Total investment of all ITS´ deployment reached the amount of 1851 k€.
