Using the same vehicles for both passenger and freight transport, to increase vehicle occupancy and decrease their number, is an idea that drives transport planners and is also being addressed by manufacturers. This paper proposes a methodology to simulate the behavior of such vehicles within an urban traffic system and evaluate their performance. The aim is to investigate the impacts of resignation from fleet ownership by a transport service company (TSC) operating on a city-wide scale. In the simulation, the service provider hires private autonomous cars for tour performance. Based on assumptions concerning the operation of such vehicles and TSCs, the software Multi-Agent Transport Simulation (MATSim) is extended to model vehicle and operator behavior. The proposed framework is applied to a case study of a parcel delivery service in Berlin serving a synthetic parcel demand.

Results suggest that the vehicle miles traveled for freight purposes increase because of additional access and egress trips. Moreover, the number of vehicles en route is higher throughout the day. The lowering of driver costs can reduce the costs of the operator by approximately 74.5%. If the service provider additionally considers the resignation from fleet ownership, it might lower the operation cost by another 10%, not taking into account the costs of system transfer or risks like vehicle non-availability. From an economic perspective, the reduction of the overall number of vehicles in the system seems to be beneficial.

使用相同的车辆进行客运和货运，以增加车辆的占用率并减少其数量，这是推动运输计划制定者的想法，并且制造商也正在解决。本文提出了一种方法来模拟这类车辆在城市交通系统中的行为并评估其性能。目的是调查在整个城市范围内运营的运输服务公司（TSC）放弃车队所有权的影响。在模拟中，服务提供商雇用私人自动驾驶汽车进行巡回演出。基于有关此类车辆和TSC的操作的假设，软件Multi-Agent Transport Simulation（MATSim）已扩展为对车辆和操作员行为进行建模。

结果表明，由于有更多的出入通道，用于货运目的的车辆行驶里程增加了。此外，途中的车辆数量全天较高。降低驾驶员成本可以将运营商的成本降低约74.5％。如果服务提供商另外考虑从车队所有权中辞职，则可能会将运营成本再降低10％，而不考虑系统转移的成本或车辆不可用之类的风险。从经济角度看，减少系统中车辆的总数似乎是有益的。
