Optimal control of freeway networks with bottlenecks and static demand
We consider optimally coordinated freeway traffic control for networks containing bottlenecks with capacity drop and hysteresis behavior. Due to the multitude of traffic jams, and the spatial and temporal relationships between control actions and traffic behavior, this problem is not as straightforward as for local control. The order in which the measures are applied may be relevant, or it may ...

متن کاملComparing a Bottleneck Identification Tool with the Congested Traffic Pattern Recognition System Asda/foto Using Archived Freeway Data from Portland, Oregon
Bottlenecks are key features of any freeway system and represent the emerging location for recurrent and non-recurrent traffic congestion. In Oregon, a freeway data archive known as PORTAL records volume, occupancy, and speed measurements from over 600 freeway locations every 20 seconds. This archive has enabled development of online freeway performance and reliability analysis tools. This pape...
متن کاملQueuing and Statistical Analysis of Freeway Bottleneck Formation
A modified approach to treat traffic flow parameters (flow, density, and speed) has been introduced in this paper. A queuing analysis has been conducted on traffic flow data on Interstate 94 in the Minneapolis–St. Paul metro area. A methodology has been developed to calibrate loop detector count data. Corrected flow data has been subjected to analysis using queuing analysis to compute densities...
متن کاملModeling Traffic at Sags
Freeway capacity decreases at sags due to local changes in car-following behavior. Consequently, sags are often bottlenecks in freeway networks. This article presents a microscopic traffic model that reproduces traffic flow dynamics at sags. The traffic model includes a new car-following model that takes into account the influence of freeway gradient on vehicle acceleration. The face-validity o...
