Advanced Applications for Urban Motorway Traffic Control

Nowadays urban motorways cannot fulfill their originally projected purpose as urban bypass due to congestions. Congestions are caused by recurrent traffic from the urban area, which tries to bypass controlled traffic intersection in the same urban area, and non-recurrent transit traffic. The problem cannot be solved by constructional build-up since they became surrounded by the urban and traffic infrastructure. This requires new approaches to make the traffic flows on them more efficient and safer. Modern information-communication technologies and advanced traffic control algorithms are introduced as an only valid approach for mentioned problems. This study proposes the latest approach of coordination between controlling on-ramp flows with ramp metering (RM) and Dynamic Route Guidance Information Systems (DRGIS), which reroute vehicles from congested parts of the motorway. In the next decades, road transport will undergo a deep transformation with the advent of autonomous vehicles, which are about to drastically change the way we commute. This paper also provides a quick overview of the Intelligent Speed Adaptation (ISA) implementation in the context of autonomous vehicles and connected driving.
