汽车共享和拼车等共享服务在现代社会中广泛传播。本文研究的是汽车共享和共乘的混合模型-“汽车共乘”。CRS是一种“车”“乘”同时共享的新型交通方式，有望降低汽车的再分配成本。我们引入CRS的情况下，两个点之间的公共汽车运输服务已经存在。我们建模这个系统作为一个排队模型，制定了一个马尔可夫链的GI/M/1型，并推导出稳态分布的排队长度。此外，我们还推导出了保证CRS正常工作所必须满足的稳定性条件以及客户平均等待时间等性能指标。在此基础上，我们进行了一些数值实验，以证明CRS的有效性和可行性。
Sharing services such as carsharing and ridesharing have been widely spreading in our modern society. This paper considers “Car Ride Sharing (CRS)” which is a mixed model of carsharing and ridesharing. CRS is a new means of transportation which shares “car” and “ride” simultaneously and it is expected to reduce the redistribution cost of cars. We introduce CRS to a scenario with two points between which transportation service by bus already exists. We model this system as a queuing model, formulated by a Markov chain of GI/M/1-type, and derive the steady state distribution of the queue-length. Besides, we derive the stability condition which must be satisfied to ensure proper function of CRS and some performance measures such as average waiting time of customers. Based on these results, we conduct some numerical experiments to show the effectiveness and possibility of CRS.
