2 Introduction 2 Introduction Optimization of a road transport network Need for optimization multiple objectives Accessibility external effects / sustainability DTM measures available Optimization expanding Local network Optimization at strategic level Use of DTM measures to affect supply

3 Introduction 3 DTM strategies

4 Introduction 4 Externalities as objectives Dynamic Traffic Management Traditionally focus on: Local level Efficiency Predefined strategies Route choice effects rarely addressed Identified as measure for externalities Local: level of service Network: influencing route choice Ideally selection DTM strategy Network level Several network performance measures All possible strategies Behavioral effects Question Suitable approach Insights in interaction between objectives Insights in effective strategies

5 Approach and challenges 5 Approach Multi-objective Incorporation of external effects Road safety Air quality Climate Noise Dynamic Traffic Management As measure Focus on supply and DTM strategies Solution approach Bi-level optimization problem Upper level: joined road authorities Lower level: road users Using DTA model for lower level Pareto optimal set provides information for decision making process Heuristics needed, computational expensive

6 Modeling Framework and solution approach 6 General Framework ARTEMIS emission model RMV or AR-INTERIM-CM noise model Accident risk based model Evolutionary Multi Objective Algorithms NSGAII SPEA2+ RSM accelerated Minimization externalities congestion, climate, noise, air quality and traffic safety Traffic dynamics Flows, speeds DTM measures Dynamic User Equilibrium problem OmniTRANS - Streamline DTA model RT version using controls DTM measures Supply link characteristics

9 Outcome optimization 9 Pareto optimal sets

10 Findings 10 Some findings AR-INTERIM-CM for noise and ARTEMIS for emissions are suitable externality models for DTA Gap in knowledge on modeling traffic safety Using RSM methods can accelerate search considerably Solving MO NDP provides a lot of information Not one single solution optimal for more than one objective Efficiency aligned with emissions substances but opposed to noise and traffic safety General strategy complex to determine, but metering of traffic can be an interesting strategy for many externalities
