FOTsis FOT’s show promising results

The FOTsis project has successfully concluded its Field Operational Tests and has a series of promising results at its disposal.

Over the last few months, the FOTsis project tested seven close-to-market services (Emergency Management, Safety Incident Management, Intelligent Congestion Control, Dynamic Route Planning, Special Vehicle Tracking, Advanced Enforcement and Infrastructure Safety Assessment) in four separate test communities in Spain, Portugal, Germany and Greece.

The processing of the data collected has led to a series of following conclusions concerning the market potential of the seven FOTsis services.

In the field of safety for example, the FOT’s in e-call have demonstrated the advantages of deploying the service from an infrastructure perspective. Through the provision of real time traffic information to the ambulance vehicle in case of an accident, the FOTsis approach can generate time savings in warning time between 1-5 minutes, which, in cases of heavy traffic, will reduce the total rescue time of about 10-15 minutes, thus increasing the chances that accidents don’t prove fatal. At the same time, by arriving at the scene of the accident before the ambulance, the road operator’s service vehicle can provide valuable information to the ambulance, which increases anticipation and allows for a more efficient handling of the accident.

With respect to ‘greener’ driving, the project has demonstrated that the use of variable speed limits can help keep traffic fluid which ca lead to time savings of approximately 7.5 % and reduction of CO2 emissions by more than 0.6 % (Intelligent Congestion Control). Similarly, by taking advantage of real-time traffic information, road operators can propose alternative routes to drivers stuck in traffic, thus reducing their estimated travel time by 5 % and emissions by 0.5 % (Dynamic Route Planning).

In terms of research questions addressed, the resulting major conclusions on mobility and sustainability can be seen in the table below, as an alternative perspective from the analysis of the services, always taking into account that most FOTsis services proposed had a very clear goal at specific impact areas (and the corresponding research questions).





Mobility and Sustainability relevant conclusions

RQ 04: Is there a change of speed?

HY 04_02: The mean speed (per road segment, route and/or network) increases.


Mean speed increases in the European motorways 0,97 Km/h (+1,04% according to the European mean speed which is 93,4 Km/h with 1 Km/h speed improvement) and 0,39 Km/h (+0,41% with 0,4 Km/h speed improvement)

RQ 05: Is there a change in travel time?

RQ 05: Is there a change in travel time?


Time savings in motorways for 1 Km/h speed improvement is 79 million hours and for 0,4 Km/h is 32 million hours, which are improvements between 0,2% to 0,47 % of the annual time spent in European motorways journeys

RQ09: Is there a change in fuel consumption?

H09_01: Fuel consumption decreases.


Savings in fuel consumption are between 1,06% and 1,45%, which mean 3,16 million tons to 4,32 million tons in the European motorways network


Savings in fuel consumption would be around 0,7%, which means 2,1 million tons in the European motorways network

RQ10: Is there a change in emissions?

H10_01: Emissions (CO2, NOX, etc.) decrease.


Emissions decrease between 1,06% and 1,45%, which mean 9,18 million tonnes  and  12,55 million tons of CO2


Savings in emissions around 6,1 million tons of CO2 in the European motorways network

RQ13: Is a change in the driver behaviour?

H13_01: Users accept the recommendations.


The acceptance of this service ranges between 60% to 80% of the European drivers

Table 1: Selected mobility and sustainability Research Questions and their main impact results findings


Safety conclusions have to be taken in a slightly different way, as there were some assumptions regarding incident related data that were not completely correct, and has resulted in a different approach to the initially planned RQ/HY. The main relevant results are:



Safety relevant conclusions


Survival rate can improve between 2,2% in metropolitan areas to 0,5% in non-populated areas so the global improvement potential on European roads and streets would rise 1,5%, saving 420 human lives per year


Accidents involved under adverse meteorological situations represent  10% of the accidents, potential accident improvements could be between 1-3% of the global accidents


4,1% of the accidents reduction obtained in this service could mean up to 2% in main motorway network


European road accidents could decrease from 1,5% to 2,5%, but in case of inadequate speed the total reduction of fatal accidents could be between 3% to 9% in the European road network


Total road fatal accidents identified, due to a long-scale implementation, could be between 40% to 55% along 15% of the road
