Abstract [en]

Increasing traffic volume in the urban areas is leading to a series of negative effects such

as congestion or emission of air pollutants. The city of Amsterdam is no exception to this

trend and a sustainable solution is sought in the area of Traffic Management and Intelligent

Transportation Systems. The goal of this study is to develop a traffic management strategy

that enhances the traffic performance in distributor roads (Plus Network Auto in Amsterdam)

during saturated conditions (AM and PM peak). After the analysis of the current state of

the traffic management in the municipality of Amsterdam, an opportunity has been detected

in which a combination of the different systems in place can be used to improve the traffic

performance of the local road network. Travel time and delay measurements retrieved from

inductive-loop detectors, automatic number plate recognition cameras and floating car data

are used in a top-level urban traffic controller that combines the traffic responsiveness of a

vehicle-actuated controller with the effective coordination of a fixed-time controller. The

proposed controller can act locally when the delay measurements show congestion at a single

intersection or along the whole corridor when the average speed drops below a specified

threshold. A microscopic simulation model of the Zuidas district for the year 2030 and the PM

peak has been used to evaluate the proposed top-level controller compared to the currently

used vehicle-actuated controller and the coordinated fixed-time controller. The results show

that the average speed in the main corridor has been increased by 28,5% and meets the

desired speed set by the municipality for the Plus Network Auto. Overall delays at the

intersections are reduced in average by 11,60% while the effect on the public transport modes

remains similar. However, the coordinated fixed-time controller has shown even a better

performance than the proposed top-level controller, for which a series of recommendations

have been issued.
