一个基于代理的，多通道模拟的市中心区域揭示了两个时移交通需求与拥挤收费，并提供额外的能力，禁止左转的影响。市中心的街道网络是理想化的，有点像洛杉矶的中心。在需求方面，价格是根据一天中的时间和旅行距离确定的。在供给方面，路网中所有路口都禁止左转，虽然单独使用这两种交通管理措施都能降低出行成本，但禁止左转的效果远不如定价。然而，当与拥堵条件下的定价相结合时，左转禁令的有效性增加了，在某些情况下增加了一倍以上。此外，这两项措施以协同增效的方式结合在一起，减少了差旅费用。在某些情况下，这种协同效应可以降低30%的成本。这种强大的协同效应表明，在考虑拥堵收费时，应将转向禁令视为一个附加选项。
An agent-based, multichannel simulation of a downtown area reveals the impacts of both time-shifting traffic demand with congestion pricing, and supplying extra capacity by banning left turns. The downtown street network was idealized, and loosely resembles central Los Angeles. On the demand-side, prices were set based on time-of-day and distance traveled. On the supply side, left-turn maneuvers were prohibited at all intersections on the network.Although both traffic management measures reduced travel costs when used alone, the left-turn ban was much less effective than pricing. When combined with pricing under congested conditions, however, the left-turn ban’s effectiveness increased considerably—it more than doubled in some cases. Furthermore, the two measures combined reduced travel costs in synergistic fashion. In some cases, this synergistic effect was responsible for 30% of the cost reduction. This strong synergy suggests that turning bans should be considered as an added option when contemplating congestion pricing.
