      Comparision of spacing and headway control laws for automatically controlled vehicles 

      Swaroop, D.; Hedrick, J. K.; Chien, C. C.; Ioannou, Petros A. (1994)
      This paper investigates two different longitudinal control policies for automatically controlled vehicles. One is based on maintaining a constant spacing between the vehicles while the other is based upon maintaining a ...

      Fuzzy traffic density homogenizer for automated highway system 

      Chien, C. C.; Ioannou, Petros A.; Chu, C. K. (IEEE, 1994)
      In this paper, a fuzzy traffic density homogenizer is proposed to alleviate or avoid the congestion by smoothing the traffic density distribution profile over the freeway. The proposed fuzzy traffic density homogenizer ...

      Intelligent cruise control: Theory and experiment 

      Ioannou, Petros A.; Xu, Z.; Eckert, S.; Clemons, D.; Sieja, T. (Publ by IEEE, 1993)
      Automated vehicle control systems (AVCS) is an important part of intelligent vehicle and highway systems (IVHS) whose long term goal is to improve freeway capacity and safety and reduce pollution through vehicle and highway ...

      Roadway traffic controller design for automated highway systems 

      Chien, C. C.; Zhang, Y.; Stotsky, A.; Ioannou, Petros A. (IEEE, 1994)
      For manual driving, the traffic flow is often irregular, unstable leading to congestion and to low traffic flow rate during minor incidents. These irregularities are due to variation of vehicle speeds and headways that are ...

      A simple roadway control system for freeway traffic 

      Zhang, J.; Chang, H.; Ioannou, Petros A. (2006)
      In this paper, a roadway control system that regulates variable speed limits along the freeway in addition to ramp metering is proposed to counteract traffic congestion and improve freeway efficiency. It treats the speed ...

      Traffic Density Control for Automated Highway Systems 

      Chien, C. -C; Zhang, Y.; Ioannou, Petros A. (1997)
      Traffic flow instabilities such as traffic congestion are often caused by ad hoc and inappropriate speeds and headways that humans choose when they operate their vehicles. In an automated highway system (AHS) environment, ...

      The use of microscopic traffic simulation model for traffic control systems 

      Chang, H.; Wang, Y.; Ioannou, Petros A. (2007)
      A highway network model is constructed using a microscopic traffic flow simulation model, VISSIM, and is intended to provide an evaluation environment for advanced traffic control systems. Since the microscopic traffic ...
