摘　　要：无人驾驶的出现将会影响通勤者的出行行为以及出行服务运营方的经营策略制定.文章基于活动的视角将无人驾驶车内活动效用以及时间利用效率纳入考虑,以一个无人驾驶车辆与地铁共存的双模式交通系统为例,构建了基于活动的双模式出行选择模型,并对地铁运营方在追求经营利润最大化与社会净效用最大化两种情形下的经营策略进行了分析优化.结果表明:基于出行的方法简化了早高峰期间瓶颈处发生拥堵的条件,同时低估了道路出行人数;当总发车班次数受限为定值时,发车间隔应随车票价格或车内活动效用的增加而缩短,同时可变成本等参数取值将会对车票价格的优化产生影响,且若忽略车内活动效用则会高估车票价格与发车间隔时间.此外,在地铁运营方以社会净效用最大化为经营目标时,虽然有着较高的社会净效用,但也承受着较高的经营成本.The emergence of autonomous vehicles will affect commuters’travel behaviors and the operational decisions for operators providing transport services.In a two-model transportation system with both driverless vehicles and transit,this paper formulates the two-mode travel choice model using the activity-based approach via taking the in-vehicle activity utility and efficiency into account,and the operational strategies are also analyzed and optimized in two scenarios of profit optimization and social net utility maximization targeted by transit operator,respectively.The results show that the congestion condition at the bottleneck during the morning rush hours is simplified and the number of road commuters is underestimated with the trip-based approach.When the transit number is constrained,the transit frequency decreases with the increase of transit fare or in-vehicle activity utility,the optimal transit fare will be affected by the variable costs and other parameters,and the transit frequency and fare will be overestimated once ignoring the in-vehicle activity utility.Additionally,the transit operator will suffer a higher operating cost although it has a higher social net utility in the scenario of social net utility maximization.
