TRAMAN21(TRAffic MANagement for the 21st Century)

Motivation and Scope

Prof. Markos PapageorgiouDynamic Systems and Simulation LaboratoryTechnical University of Crete

1. Preliminaries• ERC (European Research Council)– http://erc.europa.eu– Started in 2008– Advanced Investigator Grants: ~300/year; up to 5 years

and up to 2.5 MEURO; all disciplines, world-wide– Requirements: prior Excellence (50%); Breakthrough,

New Avenues for Research (50%)• TRAMAN21– Started in March 2013 – Strong background in Traffic Management– Scope: Motorway traffic of the future

2. Motivation• Motorway traffic: strongly degraded daily

• Motorway traffic control– Ramp metering– Variable Speed Limits (VSL)– Driver Information and Route Guidance

3. Vehicle Automation and Communication Systems (VACS)

• In-vehicle systems (automated vehicles)– Collision warning; automated queue, congestion,

and road works assistance; active green driving; obstacle avoidance; lane keeping; ACC; active lane-changing or merging system; fully automated vehicles (Google car); driver supervision; …

– Mainly for safety and convenience: ADAS– Some (few) VACS have direct traffic flow

implications

• VII or cooperative systems (connected vehicles)

– Several of the above (e.g. CACC, cooperative lane-changing, …)– Vehicles = mobile sensors– What applications?– Direct link TCC --> vehicle (e.g. route advise, VSL, lane change, …)

• Platooning– Various suggestions– Dedicated lanes?

• TRAMAN21:– Implications of emerging VACS for traffic flow

behaviour: New traffic flow modelling approaches– Intelligent vehicles may lead to worse traffic flow

efficiency: e.g. ACC with long time gaps; under-utilized dedicated lanes; informed but uncoordinated driver route choice; …

– What functions should be enabled with V2V, V2I, I2V? – Exploitation of VACS for better Traffic Management

… for an uncertain future VACS evolution and varying penetration levels

4. The TRAMAN21 Project• WP1: Overview, Analysis and Exploitation of VACS

• WP2: Traffic Flow Modelling in Presence of VACS– Microscopic– Macroscopic– Simulation tools

• WP3: Motorway Traffic Control

– Hierarchical control structure– Local control level– Network-wide traffic control– Large-scale virtual test site demonstration

• WP4: Local field test – With “conventional” VSL (+RM)

• WP5: Dissemination– Publications– Presentations and seminars– Website and video
