Why Dynafloat Proposal?

• Accessibility: growing population in urban areas (70%), limited and expensive capacity

• Complexity: traffic network with wide interactions, big networks, heterogeneous users with unpredictable behavior

• Environmental and economic cost: particles and gas emission, noise. 1Billion euros estimated cost of traffic jams (NL 2012)

Key contribution: Tools for efficient (optimal) steering of road traffic in congested urban areas using real time data

Dynafloat project 5

Scientific quality

• Stochastic operations research/ queueing theory– Uncertainties, interactions– Combined with real-time data

• New and key aspects:– Optimization on the network level– Trade-off individual users vs network optimization– Heterogeneous traffic flows– Robust control under moderate and severe congestion

Tools for efficient (optimal) steering of road traffic in congested urban areas using real time data

Outcomes and knowledge utilisation• Quantitative decision tools

queueing network models unpredictable traffic behavior interactions in urban areas KPIs: total time spent in congestion (waiting) and number of stops per vehicle

type• Models

facilitate what-if scenarios (accidents, rerouting of traffic) quantitative relation between events and consequences

• Output case studies scientific and professional publications 3 PhD theses with several master and bachelor projects

• Dissemination national European/international
