随着普适计算技术的成熟，设计新的系统来改善我们的城市生活已经成为可能。在本文中，我们介绍了一种新的城市汽车导航应用。今天运行的每个汽车导航系统都有车辆的当前位置、目的地以及当前选择的到达目的地的路线。如果一座城市的车辆可以共享这些信息，它们就可以利用交通信息在全球范围内为每辆车规划半最佳路线。因此，我们提出了一种具有路径信息共享(RIS)的协同汽车导航系统。在RIS系统中，每辆车将路线信息(当前位置、目的地和到目的地的路线)发送到路线信息服务器，路线信息服务器使用该信息估计未来的交通拥堵，并将其估计反馈给每辆车。每辆车都使用这一估计来重新规划自己的路线。然后重复这个循环。我们的多智能体仿真证实了所提出的RIS系统的有效性。使用RIS系统的司机的平均旅行时间比选择最短距离或简单最短时间估计的司机的时间短得多。此外，随着RIS用户数量的增加，城市交通拥堵总量减少。
With maturation of ubiquitous computing technology, it has become feasible to design new systems to improve our urban life. In this paper, we introduce a new application for car navigation in a city. Every car navigation system in operation today has the current position of the vehicle, the destination, and the currently chosen route to the destination. If vehicles in a city could share this information, they could use traffic information to globally plan semi-optimal routes for each vehicle. Thus, we propose a cooperative car navigation system with route information sharing (RIS). In the RIS system, each vehicle transmits route information (current position, destination, and route to the destination) to a route information server, which estimates future traffic congestion using this information and feeds its estimate back to each vehicle. Each vehicle uses the estimation to re-plan their route. This cycle is then repeated. Our multiagent simulation confirmed the effectiveness of the proposed RIS system. The average travel time of drivers using the RIS system is substantially shorter than the time of drivers who chose shortest distance or simple shortest time estimates. Moreover, as the number of RIS users increases, the total amount of traffic congestion in the city decreases.
