The FOTsis Project
FOTsis is a large-scale field testing of the road infrastructure capability for
the operation of a set of close-to-market Cooperative Services, in order to
assess in detail both 1) their effectiveness and 2) their potential for a full-scale
deployment in European roads
FOTsis represents a step forward to better connect
vehicles, infrastructure and traffic management centres
FOTsis can contribute to a safer, more intelligent and
more sustainable road transport system

FOTsis Impact Assessment
FUNDAMENTAL ASSESSMENT (Δ1)
Delta represents the improvement or worsening provided by the service.
Comparing the test-site before the service and after the service test site.
•
Quantitative assessment:
•
Source of data:
 Historical data →Review and filtering process
 Data from test-sites → Directly vs. Surrogate models
•

Use Case
• Service S1 - Emergency Management
The infrastructure centered e-Call service takes into consideration
two possible scenarios: (1) the call to the PSAP is originated from
the vehicle ; (2) user’s call is reinforced by the infrastructure
which is able to detect any incident through its own systems (DAI,
CCTV, etc.) and trigger the call.




Faster reception of the notification of an incident
Faster assigment of emergency service vehicles
Guidance to the spot of accident
Reception and sharing of improved information about incident
(location, extent, sharing of on-site pictures, etc.)

Use Case
• Service S1 - Emergency Management
Expected Impact: The improvements in the calling process may
cause a time saving in warning time around 1-5 minutes, which, in
cases of heavy traffic, will reduce the total rescue time about 1015 minutes, mainly due to the “free track” principle.

Use Case
• S1 – Quantitative Assessment
– Response Time Collected Data (elapsed time
between detection time and arrival time)
– Emergency response times in Madrid per district
– Relation between survival rate (%) and response time
(in seconds)

Conclusions and future work
• FOTsis assessment methodology proposal
• Preliminary evaluation results for Service 1 in FOTsis
look very promising:
– Faster initiation of emergency procedure by PSAP/HCC and
emergency service vehicles
– More effective deployment of resources
– Faster response time (travel/rescue time)
– Increased awareness of incident
FOTsis is a still-running
project!
