Patron Survey of Acceptable Wait Times at Transit Bus Stops in the District of Columbia

Abstract

The wait time of bus patrons at bus stops is one of several measures for assessing reliability of transit services, especially in urban areas. The uncertainty associated with waiting affects bus patrons' perception of quality of the service provided. Studies in this subject area have therefore been of interest to transit service agencies and officials. This paper presents the findings of a study conducted to determine patrons' maximum acceptable wait times (beyond the scheduled arrival time) at bus stops in an urban area. In all, 3387 bus patrons at 71 selected bus stops were surveyed over a period of 9 months. The results of the survey showed that the least acceptable wait time beyond the scheduled arrival time was 1 minute, while the maximum acceptable wait time was reported to be 20 minutes. Also, only one-third (33%) of the total number of patrons surveyed were willing to wait up to 5 minutes beyond the scheduled arrival time of buses. In addition, patrons are willing to wait longer in warm weather. On average, white patrons were found to have the least maximum acceptable wait times, followed by Hispanics, Asians, and then Blacks.

Use of High-Resolution Signal Controller Data to Measure Transit Signal Priority Performance: A Case Study in the Boston Region

“…Whether a transit priority request was rejected is meaningless to a customer; what matters is whether the travel time was reduced and/or less variable. Agencies such as Washington Metropolitan Area Transit Authority and Metropolitan Transportation Authority have also applied high-frequency AVL technology to measure travel time and control delay reduction based on the bus location and speed ( 18 ). The MBTA AVL data updates every 6 s and does not include detailed bus information (i.e., door state).…”

Performance Analysis of Public Bus Transport Services in Rural Areas

“…Figure 5 shows the percentage of passengers who tend to pay more or wait. According to Arhin et al (2019), the maximum acceptable waiting time at peak hours was found 20 minutes. Herein, at peak hours, 46.67% of the mini-buses had unacceptable waiting times and about 53.33% had acceptable waiting times.…”

“…Unpredictable traffic conditions can cause a delay in service frequency and consequently increase travel time to arrive at a selected destination. Arhin et al (2019) developed a regression model for determining the maximum acceptable waiting time depending on average headway, temperature, bus arrival time and presence of shelter. They found that the maximum acceptable waiting time of bus patrons at bus stops was 20 minutes and about 33% of the studied sample said that the most appropriate waiting time for the passengers was around 5 minutes beyond the scheduled arrival time of buses.…”
