Will all door boarding lead to savings? Exploring the impacts of all door boardings strategies on bus transit operations

北美的公交机构正在尽最大努力提供一种可以与私家车竞争的服务。在这样做的过程中，许多公交机构正在实施多种战略来改善服务，并特别注重速度。然而，在拥堵是导致公交车延误的主要因素的城市地区，公交机构经常受到公交车运行时间增加的影响。乘客活动时间是运营时间的主要贡献者之一。只有通过采用创新的票价收取办法以及改变传统的乘客活动，才能减少这一时间。例如，公交机构可以实施智能卡系统，目标是减少票价收取时间，而减少乘客活动时间可以通过购买低地板公交车、公交站点合并以及允许在高需求站点全门上车来实现。然而，实施全门登机需要考虑这一战略的机构仔细选择正确的路线或站点，这样的政策将导致大量节省。

Transit agencies in North American are doing their best to provide a service that can compete with private vehicles. In doing so, many transit agencies are implementing multiple strategies to improve service, and are especially focusing on speed. Yet, in urban areas where congestion is a dominating factor causing delay to buses, transit agencies often suffer from increases in bus running time. One of the major contributors to running time is passenger activity time. This time can only be reduced through implementing innovative approaches to fare collection as well as changing traditional passenger activity. For example, transit agencies can implement smart card systems with the goal of reducing fare collection time, while reducing passenger activity time can be achieved through purchasing low floor buses, bus stop consolidations and by allowing all-door boarding at high demand stops. Yet, implementing all-door boarding requires agencies considering this strategy to carefully select the right routes or stops where such a policy would lead to substantial savings.
