论文摘要
城市流动性涉及许多互动组件：公共汽车，汽车，通勤者，行人，火车等，使其成为一个非常复杂的研究系统。即使是负责在循环服务中将通勤者从起源传递到目的地的公交系统也已经表现出非常复杂的动态。在这里，我们研究了这样一个简化版本的这样的公交循环系统的动力学，该系统由两个提供三个公交站的公交车组成。具体而言，我们考虑将一辆公共汽车作为普通公共汽车运行的配置，该公共汽车从公交车站$ a $ a $ a和$ b $接来，然后将它们交付给公交车站$ c $，而第二辆公交车则是从公共汽车站起来的快车，然后从公共汽车站$ b $ but $ b $，然后将它们交付给公交车站$ c $ $ c $。两辆公共汽车就像不对称的代理商与公交车站$ b $耦合，因为它们通过从这个普通的公共汽车站捡起乘客进行互动。有趣的是，与两个正常总线的配置或两个Express Bus的配置相比，此\ Emph {sem-express}总线的总线效率更高，并且总线的平均等待时间较低。我们认为，效率是由半表达系统中表现出的混沌动力学产生的，在该系统中，抗束缚的趋势大于束缚的趋势，与两条普通公共汽车的常规束束行为或两辆非互动表达公共汽车的独立周期性行为相反。
Urban mobility involves many interacting components: buses, cars, commuters, pedestrians, trains etc., making it a very complex system to study. Even a bus system responsible for delivering commuters from their origins to their destinations in a loop service already exhibits very complicated dynamics. Here, we investigate the dynamics of a simplified version of such a bus loop system consisting of two buses serving three bus stops. Specifically, we consider a configuration of one bus operating as a normal bus which picks up passengers from bus stops $A$ and $B$, and then delivers them to bus stop $C$, whilst the second bus acts as an express bus which picks up passengers only from bus stop $B$ and then delivers them to bus stop $C$. The two buses are like asymmetric agents coupled to bus stop $B$ as they interact via picking up passengers from this common bus stop. Intriguingly, this \emph{semi-express} bus configuration is more efficient and has a lower average waiting time for buses, compared to a configuration of two normal buses or a configuration of two express buses. We reckon the efficiency arises from the chaotic dynamics exhibited in the semi-express system, where the tendency towards anti-bunching is greater than that towards bunching, in contradistinction to the regular bunching behavior of two normal buses or the independent periodic behaviour of two non-interacting express buses.
