“…The reliability is one aspect contributing to user satisfaction [23]. This factor can refer to an ability to carriage passengers from a starting point to an end point [24]. The reliability assessed in this work is the ability of buses to perform their intended trip from an origin to a destination along a route path under specified conditions for a given period without failure.…”

GPS Data Analytics for the Assessment of Public City Bus Transportation Service Quality in Bangkok

Evaluation of the quality of service (QoS) of public city buses is generally performed using surveys that assess attributes such as accessibility, availability, comfort, convenience, reliabilities, safety, security, etc. Each survey attribute is assessed from the subjective viewpoint of the service users. This is reliable and straightforward because the consumer is the one who accesses the bus service. However, in addition to summarizing personal feedback from humans, using data analytics has become another useful method for assessing the QoS of bus transportation. This work aims to use global positioning system (GPS) data to measure the reliability, accessibility, and availability of bus transportation services. There are three QoS scoring functions for tracking complete trips, on-path driving, and on-schedule operation. In the analytical process, GPS coordinates rounding is adopted and applied for detecting trips on each route path. After assessing the three QoS scores, it has been found that most bus routes have good operations with high scores, while some bus routes show room for improvement. Future work could use our data to create recommendations for policy makers in terms of how to improve a city’s smart mobility.

“…The fundamental parameter for the introduction of electric buses is the length of the entire route, including additional sections such as from the depot to the first stop and from the last stop to the depot [26]. Other parameters related to the local landform (elevation and depression), the road network, the availability of charging infrastructure, and the weather, the level of energy required is influenced by the need to use heating and air conditioning [27]. Existing bottlenecks on public transport routes may preclude the introduction of electric buses due to the longer time required to cover a relatively short route due to traffic congestion in these places [24].…”

A Method for the Identification of Critical Interstop Sections in Terms of Introducing Electric Buses in Public Transport

Among the activities that cities are taking to reduce the emissions of harmful substances emitted by conventional engine-powered vehicles is replacing the fleet with electric vehicles in public transport that can operate in urban areas. Fleet conversion is a process in which one of the decisions that must be made is the choice of lines that should be served in the first place by electric buses. Due to the specificity of the battery charging process, the routes of lines serviced by electric vehicles should run through sections that are as little exposed to disruptions as possible, which can adversely affect the travel time of these sections. The main goal of the article was to develop a method that supports the search for bus lines that are characterized by the highest level of reliability and punctuality and therefore also by the stability of the travel time between stops. The proposed method makes it possible to indicate critical interstop sections that have the greatest impact on the sensitivity of the line to disturbances. It was assumed that the more critical sections of the route, the greater the risk of bus delay, which may be disadvantageous in the case of electric vehicles due to the need to reach the battery charging station in time. The method was implemented on the example of selected lines in the Upper Silesian region (Poland) for data covering four years (2016–2019). The proposed approach allowed for the development of the ranking of lines, corresponding to the order in which the conventional fleet should be changed to electric.

“…This is especially important in a post-epidemic situation where the share of public transport travel has clearly decreased [12][13][14][15]. The use of public transport is improved by ensuring a modern fleet with vehicles that have environmentally friendly engines and that meet the quality expectations of passengers, such as air conditioning, smartphone chargers, free Wi-Fi, and accurate route information [16,17]. Another critical aspect in the increase in public transport trips is accessibility [18,19].…”

Assessment of Accessibility of Public Transport by Using Temporal and Spatial Analysis

et al. 2022

The development of sustainable transport is a priority in cities. It should aim to increase the number of trips made by public transport while minimizing social costs and the negative impact on the environment. The intensive development of cities from industrial to service-oriented and the phenomenon of suburbanization require changes in public transport services. However, often, operators do not change existing lines and stops or timetables justifying it with passenger habits. This approach may cause a discrepancy between the accessibility of public transport services and the demand for these services. Therefore, planning and improving the public transport system should be based on careful analyses. There are various approaches to this problem. The article presents a method to assess accessibility of public transport services using spatial and temporal analysis. The proposed method is based on dividing the area into basic fields and then, using appropriately selected measures, each field is assessed in terms of both the current level of accessibility of public transport services and the potential transport demand. A comparative analysis with the use of spatial tools indicates the degree of matching of these values and enables the identification of areas (basic fields) in which improvement of public transport services is required. For the proposed method, a case study was carried out for the city of Czeladź, located in Metropolis GZM in the southern part of Poland. The method can support decision making to improve the current public transport system.
