Formal Methods for Control of Traffic Flow: Automated Control Synthesis from Finite-State Transition Models Abstract: Today's increasingly populous cities require intelligent transportation systems that make efficient use of existing transportation infrastructure. In situations where there is a need for greater warning or direction of traffic, the use of flagpersons, automated flagger assistance devices or portable traffic signals may be required. A traffic signal's settings, also known as signal control plan, can affect road traffic significantly, particularly when disruptions first arise. Site traffic control relies upon a combination of physical features such as the selection of appropriate vehicles to carry out the necessary work in the conditions that prevail, road layout and marking, signs and signals and other considerations such as systems, procedures and training. Traffic Engineering is that branch of civil engineering which deals with the application of scientific principles, tools, techniques and findings for safe rapid convenient economic movement of people and goods. This can be achieved through junction improvements, grade separations, ramp signaling, reducing junctions, bus lanes, carpool lanes, and reversible lanes. Road infrastructure is one way to reduce potential traffic congestion problems. Performance Comparison on Traffic Control Methods for In-Vehicle Ethernet Networks.
