A Functional Architecture for Automated Highway Traffk Planning

چکیده
In a fully automated Automated Highway System (AHS), the roadside control system and the vehicles themselves are responsible for moving the large number of vehicles safely and efficiently. Therefore, the task of operating an AHS is drastically different from and much more complex than its conventional counterpart. Resulting from a large number of design options, there exist many possible ways to operate an AHS. Each of these possible operating scenarios will support a different set of functions. A crucial task in AHS R&D is to evaluate and compare these potentially large number of different AHS operating scenarios with respect to the achievable capacity. To enable simulation of various operating strategies without requiring massive program modification or database change, a flexible software structure and robust database design are required. This in turn necessitates a robust AHS functional architecture that guides the development and evolution of the required simulation tools. This paper identifies major traffic planning functions useful for optimizing the capacity of one or more major AHS operating scenarios and organizes them in a robust architecture that is modular, hierarchical, complete, expandable and integratable.

Multi-Agent Planning for Advanced Traffic Management
This paper describes two multi-agent systems developed at Southwest Research Institute to address issues in automated planning. The Autonomous Underwater Vehicle (AUV) Planning system uses multiple cooperative agents to generate a path for the AUV. The Medical Test Planning System (MTPS) consists multiple agents that incrementally build a schedule for a series of medical tests constrained by th...
متن کاملElevated Highways in Residential Layouts: The Imposed Negative Impacts (Case Study: Sadr Elevated Highway)
Fast growing population, excessive expansion of cities, and dominance of automobile in urban life have troubled cities with complicated traffic problems. In many parts of the world, transport network development has always been considered as a solution for this problem. Apparently, one-dimensional ‘traffic solutions’ would never thoroughly bring best results as the city and its problems are com...
متن کاملTowards a Functional System Architecture for Automated Vehicles
This paper presents a functional system architecture for an automated vehicle. It provides an overall, generic structure that is independent of a specific implementation of a particular vehicle project. Yet, it has been inspired and cross-checked with a real world automated driving implementation in the Stadtpilot project at the Technische Universität Braunschweig. The architecture entails aspe...
متن کاملFunctional Evolution of an Automated Highway System for Incremental Deployment
A combination of market forces, cost constraints, and other factors necessitate incremental evolution of a fully automated highway system (AHS) rather than instantaneous deployment. Thus, an understanding of the interdependencies among required AHS functional capabilities is essential for planning. This paper proposes a set of three AHS functional evolution reference models that include essenti...
