“…For example, an integration control strategy addressing both route guidance and on-ramp metering was presented [3,4]. A linear programming method was applied to the same problem where (in addition to VMS, ramp metering, or freeway-to-freeway control) traffic signal control for the urban parts of the network was also considered [5,6].…”

The problem of designing integration traffic strategies for traffic corridors with the use of ramp metering, speed limit, and route guidance is considered in this paper. As an improvement to the previous work, the presented approach has the following five features: 1) modeling traffic flow to analyze traffic characteristics under the influence of variable speed limit, on-ramp metering and guidance information; 2) building a hierarchy model to realize the integration design of traffic control and route guidance in traffic corridors; 3) devising a multi-class analytical dynamic traffic assignment (DTA) model for traffic corridors, where not only the route choice process will be different for each user-class, but also the traffic flow operations are user-class specific because the travel time characteristic for each user-class is considered; 4) predicting route choice probabilities adaptively with real-time traffic conditions and route choice behaviors corresponding to variant users, rather than assuming as pre-determined; and 5) suggesting a numerical solution algorithm of the hierarchy model presented in this paper based on the modified algorithm of iterative optimization assignment (IOA). Preliminary numerical test demonstrates the potential of the developed model and algorithm for integration corridor control.

“…Messmer and Papageorgiou (Messmer and Papageorgiou, 1990) developed a macroscopic simulation program, METANET, based on the second order model in order to investigate the traffic for motorway networks. Further research has been carried out to develop METANET (Deflorio, 2003;Breton et al, 2002;Hegyi et al, 2005, Karimi et al, 2004 Van den Berg et al, 2007). One feature of METANET is that the inflow and outflow for each node is characterised by turning ratios of traffic flows from each link that is connected to the node, as a result the effects of conflicting requirements of the traffic flows from competing directions at priority junctions are not considered.…”

This paper shows how the evolution of two-way traffic flows on a local highway network can be predicted over time, based on a network level traffic flow model (NTFM) that is used to model both urban and motorway road networks. After a brief review of the main principles of NTFM and its associated sub-models, the paper describes how a maintenance worksite can be modelled using a roadwork node sub-model and a network solution routine in NTFM. In order to model the two-way traffic flow in the road network, an iterative simulation method is utilised to generate the evolution of dependent traffic flows and queues. NTFM has been applied to model the traffic characteristics and effects of maintenance activities on the local Loughborough-Nottingham highway network. It was demonstrated that the methodology is useful in selecting various worksite arrangements in order to reduce maintenance effects on road users.

“…Furthermore, some experiments with traffic control measures have shown that these measures can influence the route choice (Haj-Salem and Papageorgiou, 1995;Taale and van Zuylen, 1999). This has led to the theoretical development of methods to incorporate the effect of existing traffic control measures on route choice (Bellemans et al, 2003;Karimi et al, 2004;Wang and Papageorgiou, 2002). In this paper however, we investigate how we can change the settings of the traffic control measures so as to steer the traffic flows towards different, desired equilibria.…”

Currently used traffic control measures, such as traffic signals, variable speed limits, ramp metering installations etc., are often not designed to influence the route choice of drivers. However, traffic control measures do influence the travel times that are experienced in the network. Since route choice is, at least for a part, based on experienced travel times, the control measures thus also influence the long-term route choice. This influence can be seen as a side-effect of the control measures, but in this paper we will investigate the possibilities to explicitly and actively use the influence of the traffic control measures to change the long-term route choice. Using basic traffic flow and route choice models we investigate how outflow and speed limit control can affect the final equilibrium turning fractions. As an example we consider a case study for a simple network with two routes and use a simple linear outflow controller, which makes the analytical investigation of the effects of the controller possible, but the results can be extended to more sophisticated control methods.
