8 8 S.I.MO.NE Project: Architecture

9 9 Gathered Floating Car Data (FCD) Raw Data (RD): speed, position, time of measurement (usually according to NMEA 0183). Position without any map-matching elaboration; Raw Data Public Transport (RDPT): similar to RD, generated by Public Transport Automatic Vehicle Monitoring (AVM) systems; Map-matched Raw Data (MRD): still consists in speed, position and time, but position is map-matched and associated to the reference system used by Fleet Manager; Travel Time (TT): aggregated information, the travel time for each single element of the geographic reference system.

10 10 Different Reference Systems: Graphs For G1 TMC has been chosen in the project, because TMC is a standard and currently the main Italian Fleet Managers are able to provide TT data aggregated on TMC reference; G2 graph used by the Aggregator has to be detailed as much as possible, in order to aggregate RD and RDPT; G3 graph used by the Supervisor functionality is defined to represent the main roads of the real roads network; it has been decided to adopt G3 graph also in the Aggregator and so G3 and G2 are the same; G4 graph used by the Information Policy Manager is designed in order to provide information, in the project has been chosen TMC; For G1 TMC has been chosen in the project, because TMC is a standard and currently the main Italian Fleet Managers are able to provide TT data aggregated on TMC reference; G2 graph used by the Aggregator has to be detailed as much as possible, in order to aggregate RD and RDPT; G3 graph used by the Supervisor functionality is defined to represent the main roads of the real roads network; it has been decided to adopt G3 graph also in the Aggregator and so G3 and G2 are the same; G4 graph used by the Information Policy Manager is designed in order to provide information, in the project has been chosen TMC;

11 11 Aggregator module: Data fusion and completion The data sent by several Fleet Managers are collected by the Aggregator, in order to carry out Data fusion and Data completion; Data are filtered and then projected on the geographic reference system used by the Aggregator (G2); RD and RDPT are elaborated by a map-matching algorithm that associates the GPS coordinates (latitude, longitude) to the relevant basic element of the geographic reference system, typically an arc of the graph; RD data are also elaborated to identify the traces of the vehicles, identifying the start and the end of each single performed travel using Key-on and Key-off signals, to be used by an algorithm to create O/D (Origin/Destination) matrix; For MRD and TT data the Aggregator translates the received geo- reference information and matches it with the relevant element in its own geographic reference system.

12 12 Aggregator module: Travel Time (TT) calculation (1/2) To calculate TT on basic geographic element of the Aggregator graph or on aggregation of basic geographic elements (functional classes), the following data are needed: –Start and end points over the arc (Map Matching); –Start and end timestamps; –Calculate T=Tend-Tstart –Calculate L=Lend-Lstart ; To calculate TT on basic geographic element of the Aggregator graph or on aggregation of basic geographic elements (functional classes), the following data are needed: –Start and end points over the arc (Map Matching); –Start and end timestamps; –Calculate T=Tend-Tstart –Calculate L=Lend-Lstart ;

13 13 Aggregator module: Travel Time (TT) calculation (2/2) The aggregation process calculates TT on a per arc basis starting from incomplete TT-FCD relevant to portion of arc; this is executed on the base of two approaches: 1.Mean TT on minimal element (portion) of the arc: the arc TT is the sum of minimal element TT 2.Mean TT on arc: mean of all TT-FCD value is calculated, then the speed is calculated to get the TT of the complete arc.

14 14 Aggregator module: Minimal requirements The TT-FCD are aggregated on a per time frame basis and on geographic reference system elements (single arcs, functional class, etc.); minimal requirements for good data aggregation and TT calculation are: –sampling of data has to be performed according to a distance based criteria and not on time base, since the total number of samples have to depend from travelled distance and not from travel time spent; –sampling data frequency has to enable Travel Time calculation on arcs, average length of 90 metres in the urban areas and 150 metres in the suburban one; –a sampling step of 30 metres shall guarantee a coverage of 94% of the total road network.

15 15 Final Field Test sperimentation The project will be finally validated with Field Trials that: Will cover the areas of Turin, Bologna, Cagliari, Genoa and Florence cities, (roughly of inhabitants); Will use data coming from a fleet of vehicles; Will involve main Italian private leader companies operating in the market: Centro Studi Sistemi di Trasporto (CSST- FIAT Group), Infoblu (Autostrade per lItalia Group), Magneti Marelli and Telecom Italia (tema.mobility consortium); –Will test usage of FCD together legacy fixed-sensor traffic monitoring equipments; –Will demonstrate the improvement of traffic monitoring via usage of FCD, that increase data accuracy and geographic coverage; –Will test usage of standard protocol with large amount of real time information; –Will prove the scalability of the architecture facilitating the growth of FCD market and the set-up of new TOCs.

16 16 Project Benefits The adoption of the S.I.MO.NE. architecture will bring the following main benefits: –Cost reduction: FCD will reduce traffic data collection costs since less fixed-sensor equipments will be needed; –Data accuracy and enhancement of geographic coverage; –Service enablers: providing real-time info to drivers (e.g. road works, traffic limitations, traffic flows, congestions); –New opportunities for ITS market growth.
