公交系统的可靠性是一项关键的性能衡量标准，因为它是客户决定乘坐铁路和公交系统的主要因素，尤其是在城市地区。几个性能指标被用来评估运输系统的可靠性，包括准时到达和顾客满意度。华盛顿大都会交通管理局（WMATA）建立了一个公交车站准时到达的范围，即比广告中的预定到达时间早两分钟，晚七分钟。然而，大多数地区公交公司使用的是比广告中规定的到站时间早1分钟和晚5分钟作为其准点率范围。这项研究确定了WMATA的公交车在多大程度上满足了其78%的准点率目标。公交到达数据也被用来确定WMATA在美国几家城市公交机构使用的早到1分钟和晚到5分钟范围内的准时表现。在WMATA的早到2分钟和晚到7分钟的范围内，发现公交车在上午旅行中准点率约为82%（平均）。在晚上，在相同的范围内，平均68%的公交车被认为是准时的。总体准点率为75%，较2010年74%的准点率略有改善。利用几家地区公交机构采用的早到1分钟和晚到5分钟的范围，发现公交车在早上的准点率约为67%，在晚上为55%，总体准点率为61%。
Transit reliability is a critical measure of performance since it is a major factor used by customers in making decisions on travel by rail and bus systems, especially in urban areas. Several performance metrics are used to assess the reliability of a transit system which include on time arrivals and customer satisfaction. The Washington Metropolitan Transit Authority (WMATA) established an arrival range of two minutes earlier and seven minutes later than the advertised scheduled arrivals at bus stops as the range for on-time performance. Most regional transit agencies, however, use a one minute earlier and five minutes later than the advertised scheduled arrivals at bus stops as their on-time performance range. This research determined the extent to which WMATA’s buses satisfy its performance goal of 78% for on-time arrivals. The bus arrival data was also used to determine WMATA’s on-time performance under the one-minute early and five-minutes-late arrival range used by several urban transit agencies from across the United States. For WMATA’s 2-minute early and 7-minute late arrival range, the buses were found to be on-time approximately 82% (on average) of the time during the morning travel. In the evening, for the same range, on average, 68% of the buses were considered to be on-time. This resulted in an overall on-time performance of 75% which is a modest improvement over the 2010 on-time performance of 74%. Using the 1-minute early and 5-minute late arrival range employed by several regional transit agencies, the buses were found to be on-time approximately 67% of the time during the morning and 55% in the evening, resulting in an overall on-time performance of 61%.
