Success Story: Eix Transversal Barcelona, Spain

The Eix Transversal (C-25) is a 150 km long section of a crucial Inter-European motorway connecting the Iberian Peninsula with central and eastern Europe. It runs to the north-east of Barcelona, in the region of Catalonia in Spain. This motorway was  expanded in 2013 from two to  four-lanes by a concessionaire that has the exploitation rights for 33 years under a shadow toll contract. This widening  improves traffic safety and enhances inter-regional connections between the plain of Lleida and Girona encouraging territorial balance and economic development in the Catalonia’s inland regions.  Daily traffic is over 17.000 vehicles, of which between 20 and 30% are heavy vehicles.

Business Challenge

Gathering accurate counting information was critical for the concessionaire’s business as it is paid by the number of vehicles that use the motorway. The concessionaire required a solution with a minimal impact on the infrastructure, high accuracy, and a low total cost of ownership over the exploitation period (33 years). Inductive loops, even when are a tested technology, required extensive cabling, expensive trenching, as well as frequent calibration to maintain accuracy. The coverage of other technologies like video, radar and laser proved to be insufficient, and had accuracy issues due to limitations in range and weather interference.

Solution

Sensefields smart infrastructure solution was selected by the concessionaire to provide business-critical technology, as it fulfilled the totality of the requirement in terms of ease of installation, accuracy, and total cost of ownership and offered an enhanced traffic management platform. Thirty-nine (39) vehicle detection stations, with a total of 520 sensors, were deployed throughout the Eix Transversal. In addition, a traffic management system, Fastrack, was put into operation for real-time monitoring of the infrastructure, and for online analysis of traffic information. Fastrack was also integrated with other existing management applications for billing and business planning. On-road maintenance of sensors is carried out by the concessionaire, not requiring any specialized personnel or tools. Sensefields provides technical support for the solution including software updates, remote configuration, diagnostics and maintenance.
