摘要：In order to improve the travel time of surface public transport vehicles (PT)
(bus, tramway, etc.), several cities use urban traffic control (UTC) systems
enabling to give priority to PT. This article reviews these systems. Further to
a debate on their insufficiencies for a global regulation on the urban traffic
on a whole network, the paper proposes intermodal regulation strategies,
operating on intersection traffic lights to regulate traffic, favoring the PT.
These strategies are based on the linear quadratic (LQ) optimal control theory.
The article proposes different ways to take the PT into account in the
optimisation problem. The simulation tests are carried out on a network of eight
intersections and two PT lines.
