Traffic Light Coordination - Impacts on mobility

Transcription

1 Consortium Meeting Madrid 2013 May, 8 th Traffic Light Coordination - Impacts on mobility Roma Servizi per la Mobilità S.r.l. Rome Mobility Agency Marco Cianfano

2 Key issue The context Mobility Planning in Rome Present vs Mid term scenario ICT Emissions: case study overview Traffic survey ICT on and off Preliminary Results

3 The context: Rome City of Rome Province of Rome Municipal Area skm Population Metr. Area City residents Road Network km Main road network km. 800 Vehicles cars wheels goods delivery Daily Trips Peak-hour Trips

4 Management of the Mobility 5 concentric zones with increasing constraints Zone 5: Municipality Area 1285 km 2 Emission Check Blue Label (yearly all vehicles and PTWs) Zone 4: External Ring (GRA) 344 km 2 Tourist Coaches Regulation Zone 3: Green Belt 154 km 2 Pollution emergencies, Multi-modal nodes, Park&ride Zone 2: Rail Ring 48.4 km 2 Emission restrictions, Pay parking schemes Zone 1: LTZ 5.5 km 2 Stop to all vehicles (except permit holders) Pedestrian 0.5 km 2 Zero Emission Area (walking & electric)

11 CO2 Emission (tons/year) Present vs Short term scenario

12 Objectives and Rome case study ICT EMISSIONS Development of a methodology and tool to evaluate the impact of ICT measures on road transport emissions Type of ICT/ITS Traffic Management with particular regards to Traffic Lights Optimization

13 Rome case study - Overview Itinerary of 6,1 km Urban Road: 2000/4000 veh/h 23 TRAFFIC LIGHTS (under UTC system: plan selection scheme)

14 Rome case study - Survey 2013, April 9 th 2013, April 10 th 2013, April 11 th UTC ON - 6 hours/day - Morning Peak (7:30/9:30) - Afternoon Off peak (12:30/14:30) - Afternoon Peak (17:30/19:30) UTC OFF UTC ON - 2 vehicles with GPS and Engine/fuel monitor systems - Fiat Punto - Fiat Panda 1.3 MJ - Survey Numbers: - 67 trips travelled km

15 Rome case study Traffic flows Number of Vehicles [veh/5 mins.] CITY CENTRE 09/04/ /04/ /04/2013 Similar traffic level over the three days of survey, in both directions (city centre and GRA) 09/04/ /04/ /04/ Time of the Day Effects of UTC off can be read without considering traffic conditions GRA Time of the Day Number of Vehicles [veh/5 mins.]

28 Rome case study Preliminary conclusions - Important effects on travel times and speed - Stop and go effect increases - More the traffic flow is high more the UTC effetcs is important (platoon effects??) - Fuel consumption???
