Speed Advisory and Signal Offsets Control for Arterial Bandwidth Maximization and Energy Consumption Reduction
Résumé
The problem of maximizing bandwidth along an
arterial is addressed here by use of two combined control actions:
traffic light offsets and recommended speeds. The optimization
problem has been enriched in order to account for traffic energy
consumption and network travel time, thus avoiding impractical
or undesirable solutions. A traffic microscopic simulator has been
used to assess the performance of the proposed technique in terms
of energy consumption, travel time, idling time, and number of
stops. The correlation of theoretical bandwidth with known traffic
performance metrics is studied, and an analysis of the Pareto
optimum has been carried out to help the designer choose a
tradeoff in the multiobjective optimization. Finally, an evaluation
of the traffic performance at different levels of traffic demand
aims at showing the best operation conditions of the proposed
strategy. A demand-dependent optimization is proposed.
