  • Emergency Vehicle maneuvers and control laws for automated highway systems
    IEEE Transactions on Intelligent Transportation Systems, 2002
    Co-Authors: C Toy, K Leung, Luis Javier Alvarez, Roberto Horowitz
    Abstract:

    The operation and transit of Emergency Vehicles (EVs) on an automated highway system (AHS) designed under the control architecture proposed in the California PATH (Partners for Advanced Transit and Highways) program is described. The term "EVs" is used in a general sense to describe Vehicles such as police cars, ambulances and tow trucks, that may service faults inside or outside the AHS. The transit of EVs requires intensive participation of the coordination layer, which directs the interactions of neighboring Vehicles, and the link layer, which regulates traffic flow along stretches of highway. Various strategies for these two hierarchical layers that are needed to assign high-priority transit to EVs on the AHS are described. These coordination- and link-layer maneuvers circulate other Vehicles around the EV in both free-flowing and stopped traffic.

  • Emergency Vehicle maneuvers and control laws for automated highway systems
    Proceedings of the ASME Dynamic Systems and Control Division (1998), 1998
    Co-Authors: C Toy, K Leung, Luis Javier Alvarez, Roberto Horowitz
    Abstract:

    This paper describes the application of the control architecture in the California PATH program to the operation of Emergency Vehicles. The technique involves participation between the coordination and link layers. Different strategies for the two layers are described as they assign high priority transit to Emergency Vehicles on an automated highway system (AHS). The two layers allow other Vehicles to move around the Emergency Vehicle in both free flowing and stopped traffic.

  • Design of Traffic Safety Control Systems for Emergency Vehicle Preemption Using Timed Petri Nets
    IEEE Transactions on Intelligent Transportation Systems, 2015
    Co-Authors: Yi-sheng Huang, Yi-shun Weng, Mengchu Zhou
    Abstract:

    Timed Petri nets (TPNs) are useful for performance evaluation of discrete event systems due to their mathematical formalism. This paper focuses on their use to model the preemption of Emergency Vehicle systems. The advantage of the proposed approach is the clear presentation of traffic light behaviors in terms of conditions and events that cause the preemption of phases being changed. The resulting models allow one to identify and thus avoid urgent spectacles in such systems by conditions and events of the model that control the phase of traffic light alternations. Moreover, this work proposes a new Emergency Vehicle preemption policy to ensure that Emergency Vehicles can pass through intersections with no or less delay. The analysis is performed to demonstrate how the models enforce the phase of traffic transitions by a reachability graph with time information. The liveness and reversibility of the proposed model are verified. To our knowledge, this is the first work that employs TPNs to model an Emergency Vehicle preemption system and identify its urgent spectacles for the purpose of their complete avoidance. This helps advance the state-of-the-art in traffic safety related to the intersection of roadways.

  • Reducing Emergency services response time in smart cities: An advanced adaptive and fuzzy approach
    IEEE, 2020
    Co-Authors: Djahel Soufiene, Smith Nicolas, Wang Shen, Murphy John
    Abstract:

    The First IEEE International Smart Cities Conference (ISC2-2015), Guadalajara, Mexico, 25-28 October 2015Nowadays, the unprecedented increase in road traffic congestion has led to severe consequences on individuals, economy and environment, especially in urban areas in most of big cities worldwide. The most critical among the above consequences is the delay of Emergency Vehicles, such as ambulances and police cars, leading to increased deaths on roads and substantial financial losses. To alleviate the impact of this problem, we design an advanced adaptive traffic control system that enables faster Emergency services response in smart cities while maintaining a minimal increase in congestion level around the route of the Emergency Vehicle. This can be achieved with a Traffic Management System (TMS) capable of implementing changes to the road network\u27s control and driving policies following an appropriate and well-tuned adaptation strategy. This latter is determined based on the severity of the Emergency situation and current traffic conditions estimated using a fuzzy logic-based scheme. The obtained simulation results, using a set of typical road networks, have demonstrated the effectiveness of our approach in terms of the significant reduction of Emergency Vehicles\u27 response time and the negligible disruption caused to the non-Emergency Vehicles travelling on the same road network.Science Foundation Irelan
