1 ITS CORRIDOR MedTIS - MEDITERRANEAN CORRIDOR DEPLOYING TRAVELLER INFORMATION SERVICES IN THE FIELD OF THE TRANS-EUROPEAN TRANSPORT NETWORK (TEN-T) 2013-EU P C(2014) 8455 PROJECT REFERENCE PROJECT NAME PROJECT LOCATION FRA-02 Travel Time inter-motorway and international networks A7 motorway French-Spanish cross-border section 200km of network 1. I S S U E S A D D R E S S E D B Y T H E P R O J E C T 1.1 NATURE OF THE SITE With a 2,600 km long network embedding an average annual daily traffic of 110,000 veh/day made up of 20% of heavy goods vehicles; ASF network is one of the busiest networks in Europe. On the considered A7 stretch embedding French-Spanish cross-border section, traffic characteristics are the following: - An average veh/day - Peak traffic up to veh/day - Peak HGV traffic up to 30% of vehicles 1.2 ISSUES ADDRESSED The characteristics of this road embed a number of constraints: - High volume of daily traffic on critical sections - High rate of freight traffic - Peak traffic during summer time (holiday itinerary seasonal migration) - Connections and go-through major conurbations (Barcelona Perpignan) - Combined use of long-distance and daily trips - Cross-border interfaces - Mountainous areas - High volume of international road users 2. P R O J E C T D E S C R I P T I O N 2.1 PROJECT OBJECTIVES Service area: Traveller Information Services Key words: Travel time, continuity, cross-border Project objectives: - Cross-border continuity upgrade of Travel Time Information (French-Spanish border) through data aggregation - Inter-operators data aggregation: complementary software developments on the existing travel time system aiming to exchange Travel time information between road operators (namely ASF and ACESA). - Service quality upgrade: dissemination of aggregated travel time along ASF section on the Mediterranean corridor. - Set up a real-time traffic information service permanently available with several dissemination channels.

2 - Ensure travel time information continuity with ASF neighbouring networks, namely ACESA operating in Spain (i.e. cross-border continuity). 2.2 SYSTEMS AND TECHNOLOGIES APPLIED Project consists in: - Creation of fusion algorithms allowing to feed the processing engine with several data sources: traffic counting stations, toll data; - Setting up of cross-border systems allowing to process and disseminate on French A7 motorway cross-border travel time information up to Barcelona; - Setting up of systems supporting permanent (24/7) process and dissemination of travel time information; display on access VMS to inform incoming customers and mainline VMS in order to ensure a 30-minute customer information frequency. Specifically: - Implementation verification and calculation system; - Travel time information display on VMS, on the network and before entering the motorway (tollgate); - Travel time information available on ASF website and via 107.7FM motorway isoradio. Global System is based on two modules based on real-time traffic conditions: - Processing engine calculates every 6 minutes the travel times of for then 750 journeys and is fed with 3 types of data : the real-time toll data, ANPR data and the traffic counting stations data; - Real-time dissemination system is fed with the calculation results from the processing engine and ensures the dissemination on several channels (400 VMS spread along the 2,600 km-long network, radio and internet) once the calculation is done. 2.3 PROJECT COSTS The implementation of travel time calculation (data collection and consolidation, algorithms fusion and processing) is estimated 30k. Annual operating cost is estimated 3 k. 2.4 PROJECT STATUS French-Spanish cross-border continuous travel time is deployed, reliable and operational and in service since July E V A L U A T I O N P L A N 3.1 OBJECTIVES FOR THE EVALUATION Evaluation of this project focused on the following targets: - Impact of the activated system on traffic conditions - Accuracy of information provided to customers according to real-time traffic situation - Customers satisfaction The following Key Performance Indicators have been calculated: Category Congestion Definition Reduction of congestion hours on strategic bottlenecks of the MedTIS MedTIS - Project Evaluation - FRA_02 Travel Time ASF_ doc 2

When travel times strongly increase road users use rest areas to have a break or even plan an itinerary adjustment. These changing of behaviour contribute to a reduction of road congestions. In this regard, other things being equal, traffic congestion measure before and after activation of a TTI measure provide a clear indication on its benefits. Traffic congestion measure is a standard KPI on ASF network, based on the measure of HKM or Hours KiloMetres. French convention on HKM calculation is the following: HKM = on a located section, congestion volume is the product of the duration (in hours) of the congestion by its average length (in km) on one lane. 1 HKM = 1 hour of congestion on one line of 1km Loss hours: One assumes that 1 HKM equals 20 loss hours for road users: - Speed reduction: from an average 110 km/h to an average 50 km/h - Density: 35 vehicles/km - Traffic: vehicles/hour METHODOLOGY ADOPTED ON THIS PROJECT Considering that project FRA-02 - Travel Time inter-motorway and international networks has been deployed and operated during summer 2015, ASF operators are lacking background to specifically evaluate the impact of this measure on the considered section. However ASF has gathered experience on the deployment of the same service on comparable motorway sections. In that sense it is possible to estimate the potential for benefit (and associated KPI) of FRA-02 - Travel Time inter-motorway and international networks. ASF chose to base its approach on the following section: neighbouring A9 motorway section Montpellier-Narbonne. Its characteristics are highly comparable to the neighbouring section considered within FRA-02: long distance transit, large amount of foreigner drivers, seasonal peak migrations (notably during summer holiday), large proportion of Heavy Goods Vehicles. On neighbouring section A9 Montpellier-Narbonne Travel Time Information service has been activated during ASF decided to measure congestion levels on this section before (2008, 2009) and after (2011) activation of TTI service.

4 Narbonne HKM HKM HKM HKM % evolution / +.6% % TTI service impact / / % Consideration of A9 Montpellier-Narbonne section between 2008 and 2011: - Traffic volumes: stable, around veh/day; up to veh/day during summer peak periods - Infrastructure: no major evolution or modification - Travel Time Information service activation on VMS: 85% of time, 15% remaining allocated to specific event information On this basis ASF assumes that TTI service activation has a strong impact on network congestion reduction. To evaluate the specific contribution of TTI service on network congestion, ASF reduces its direct impact to 50% of HKM reduction (safety coefficient). On this basis, on comparable motorway sections, ASF expects a 17% reduction of HKM the year following the activation of Travel Time Information service. 4. E V A L U A T I O N R E S U L T S 4.1 LEVEL OF DEPLOYMENT / LEVEL OF SERVICES The service is operated on a 200 km long motorway section including a cross-border section. Thanks to this ITS service deployment this road section reaches the highest Level of Service as previously defined: Level 4 - Enhanced TIS services available: including service continuity at crossborder sections, service continuity inter-operators, combination of high-level TIS services 4.2 IMPACTS / BENEFITS IMPACT ON CONGESTION Based on the methodology exposed beforehand, ASF expects a 17% reduction of HKM on the section following the activation of TTI service measure. A7 French-Spanish cross-border section Perspectives HKM HKM HKM % evolution / - 17% TTI service impact / A 17% reduction of HKM on this section corresponds to HKM spared during one year. According to the principles detailed beforehand, TTI activation on A7 French-Spanish cross-border section should contribute to spare an average loss hours for road users in Travel Time Information service activation on A7 French-Spanish cross-border section in a nutshell: - 17% of congestion reduction expected MedTIS - Project Evaluation - FRA_02 Travel Time ASF_ doc 4

5 loss hours spared for road users the year after implementation IMPACT ON THE ENVIRONMENT ASF based its reflexion on the following items to conduct a project evaluation on the environmental impacts: Gas consumption considerations: within congestion situation consumption is increasing by 50%. Gas consumptions /100km on motorway Normal traffic conditions Average gas consumption Traffic congestions Average gas consumption Light vehicle 7 l/100km 10.5 l/100km Heavy Goods Vehicle 32 l/100km 48 l/100km Fluid traffic (vs. traffic congestions) contributes to spare: 3.5 l/100 km (0.035l/km) for light Vehicles and 16 l/100 km (0.16l/km) for HGV. Traffic flow considerations in congestion situation: - Average vehicle concentration is estimated 35 vehicles/km/line. - average flow debit is estimated veh/hour The following table aims at evaluating the extra gas consumption per HKM. It is based on the conservative assumption that traffic is made of 90% of light vehicles. Gas extra consumption per HKM Average flow debit [a] % vehicle [b] Extra gas consumption per vehicle/km [c] Gas extra consumption l/hkm [axbxc] Light vehicle HGV TOTAL HKM represents an extra litres of extra gas consumed by the vehicles involved in the congestion Regarding CO2 emissions one admits that considering the mix of light vehicles and HGV on the network, 1 litre of gas generates 2.7 kg of CO2. Conclusions for the project: Spared HKM [a] Extra gas consumption per HKM [b] Gas consumption spared in litre [axb] CO2 emission per litre of gas [c] CO2 emissions spared in tons [axbxc] On this project, an annual reduction of HKM contributes to a CO2 economy of tons per year IMPACT ON SAFETY MedTIS - Project Evaluation - FRA_02 Travel Time ASF_ doc 5

6 Impacts on safety have not been specifically evaluated. However one admits that informed road users having clear knowledge of their travel time are more focused on their driving behaviour. The proper contribution of Travel Time Information services to safety may be assessed in a further project evaluation. TECHNICAL PERFORMANCE The technical results of the project can be considered as the capability of the system to display travel times on the motorway s VMS, when no more important information have to be displayed. Several measurements have been made and it could be concluded that in 99.3% of the cases which the travel time have to be displayed, it is effectively displayed. END USER ACCEPTANCE A customer s satisfaction survey has been realized in falls 2010 on 600 drivers and on the whole network: - The reconnaissance rate of the Travel Time Information by end-users on VMS is 86% % of interrogated drivers say this information is useful to manage and optimise their travel time. 4.3 COSTS BENEFITS ANALYSIS ASF adopted the following assumption when evaluating CBA: 1 loss hour is estimated (based on a traffic share of 90% light vehicles boarding 2.3 persons and 10% HGV). On this project, an annual reduction of loss hours contributes to saving for the EU citizens of This figure has to be compared to the actual cost of the project which is estimated 30k in investment and 3k in annual operation. 5. E U R O P E A N D I M E N S I O N ASF has been promoting the deployment of Travel Time Information services for a long time. Having in charge one of the busiest motorway network in Europe, the road operator supports solutions which have proven their efficiency. The result figures of this evaluation show the positive impact of the measure on traffic conditions, on the Environment and on socio-economic dimensions. The service is now technically mature and knowledge can be transferred between road operators. Results of this evaluation can be considered by road operators coping with similar road geometry and traffic conditions.
