Background The study of user satisfaction with public transport services is of key interest for enhancing public transport ridership. However, the elevated risks of virus transmission on public transport associated with COVID-19 have resulted in a shift towards private vehicles. This issue is of concern to policymakers due to reduced levels of publ...
Article
The allocation of street space is strongly contested in many cities, particularly in areas where there is a high level of people activity. In these areas, movement and place objectives are often in conflict with one another. The allocation of street space involves a range of governance, political and ethical considerations, yet efforts to reallocat...
Article
COVID-19 has been associated with a decline in public transport ridership in many cities. However, the impact of the pandemic on passenger perceptions of public transport, particularly loyalty, remain largely unexplored. Using a case study of Tehran’s bus system, this paper aims to assess the moderating effect of COVID-19 on passenger loyalty. A cr...

The allocation of street space is strongly contested in many cities, particularly in locations such as activity centres where high traffic flows conflict with popular places and key destinations in their own right. Despite the stated importance of allocating street space in an equitable manner, few studies have explicitly measured how much actual s...
Article
Minimum off-street residential parking requirements are used in many cities as a way to accommodate parking demand associated with new residential development. In some cases, variations to these requirements are used in the form of reduced (or eliminated) minimums and/or maximum parking requirements to more actively manage parking demand. This pape...
Article
Recent decades have seen a global resurgence in tram network development around the world. Despite a primary basis in transport, tram network development is increasingly framed as a spatial planning mechanism that is prioritised for its potential place-based outcomes. However, there has been limited academic research to investigate impacts of tram...

Autonomous vehicles (AVs) potentially increase vehicle travel by reducing travel and parking costs and by providing improved mobility to those who are too young to drive or older people. The increase in vehicle travel could be generated by both trip diversion from other modes and entirely new trips. Existing studies however tend to overlook AVs’ im...

Article
Public transit is widely recognized to reduce urban traffic congestion, as it encourages automobile travelers off the road. However, streetcars have been criticized for causing traffic congestion since large trams must operate in mixed traffic on narrow, congested streets. At the same time, streetcars reduce congestion by encouraging automobile dri...

... The first step in preparing for a post-COVID era with public transport is assessing user satisfaction during the pandemic to inform the development of policies to support safe and reliable services and to retain ridership levels. In this regard, studies on the impact of COVID-19 on public transport have been conducted separately in fields such as loyalty (Esmailpour et al., 2022), ticket validations, sales and passenger counts (Jenelius and Cebecauer, 2020), ridership, frequencies (Tiikkaja and Viri, 2021) and crowding perceptions (Aghabayk et al., 2021;Cho and Park, 2021). Given this, there is a need to integrate the effect of the COVID-19 pandemic on the service quality of public transport. ...
... Meanwhile, satisfaction with reliability, public transport frequency, comfort, and safety had a significant influence on urban public transport usage in only one-third of EU countries [14]. Moreover, the frequency of PT use has been explored among residents who have moved to outer suburban greenfield estates along with factors that are associated with these changes [15]. It has also been found that the frequency of use of transport is influenced by changes in the built environment, including the quality of public transport services among those who move to a new residential location [16]. ...
... Streetcar, which is generally defined as one type of rail transit system operating entire routes typically on streets in mixed-traffic with lighter vehicles, shorter station distances, and providing medium/low passenger capacity [12,13], is undergoing a resurgence both in China and overseas. Many reasons have driven the streetcar's return to the urban transportation scene, including rapidity, passenger comfort, relatively low construction cost, and environmentally friendly vehicles [14]. ...
... Arentze (2011) [26] estimated the dynamic generation and got an result with 27.2%. Other researchers such as Gruyter(2021) [27] used R-square to evaluate the correlation among trip generation and influential factors and got results with the percentage error of 16.5%. Patil (2021) [28] modeled the freight trip generation of restaurants and got results with the percentage error of 11.9%. ...
... Types of pedestrians can be defined using a mathematical models which are one of the steps of an algorithm based on some variables [1] [2]. High traffic volume can cause traffic congestion [3] [4] that may lead to traffic crashes [5] [6] [7], also can cause high level of noise exposure that has a negative effect on human health, especially near the heavy traffic roads [8][9] [10]. The level of noise is measured in decibel (dB) which is a unit of measurement of sound intensity. ...

In contrast, if users' subjective optimal expectations are chosen as the decision-making aim, there will inevitability be a problem in that users' subjective optimal expectations will not be achievable due to the restrictions of practical conditions. (2) In the process of product design, not just technology, materials, and components are considered, but those are considered as well [8][9][10]. is, the user's volatility should be taken into consideration during the evaluation process. ...
... Street characteristics were largely determined through site visits, while activity centre characteristics were compiled using GIS and secondary data sources. The activity centre characteristics, while not exhaustive, represent various built environment and socio-demographic factors that have been found in previous research to be associated with travel behaviour (Boulange et al., 2017;De Gruyter et al., 2020;Ewing and Cervero, 2010), plus variables that are relevant to planning complete streets (Dehghanmongabadi and Hoskara, 2020). It was therefore hypothesised that these factors could also be associated with the use of each transport mode in the activity centres. ...

It is a diverse factor that provides the public transport quality on the passengers' perspective according to frequency of service, mode, fares, and hours of operation to include internet services (De Gruyter, & Currie, 2019). ...
... Satisfaction with the primary care visit is positively affected by walking to primary care and negatively affected by travel time to primary care. Gunn et al. (2020) review planning policies identifying environmental features known to support healthy and active behaviours. For residents in two case studies in Melbourne (Australia), they find that those living in places where destination and transport access are relatively poor are less satisfied, whilst those in the more walkable areas are more satisfied. ...
