Mixed findings have been reported in previous research regarding the impact of built environment on travel behavior, i.e. statistically and practically significant effects found a number empirical studies insignificant correlations shown many other studies. It is not clear why estimated stronger or weaker certain urban areas, how effective proposed land use change/policy will be changing behavior. This knowledge gap has made it difficult for decision makers to evaluate plans policies...
Encouraging more cycling is increasingly seen as an important way to create sustainable cities and improve public health. Understanding how cyclists travel encourage requires data; something which has traditionally been lacking. New sources of data are emerging promise reveal new insights. In this paper, we use from the activity tracking app Strava examine where people in Glasgow cycle forms could be utilised better understand patterns. We propose a method for augmenting by comparing...
Many local authorities in the UK and other developed countries have spent a substantial amount of time money providing safe cycling infrastructure to improve environments. However, it is not clear whether these expensive physical investments are an effective strategy encourage people cycle more cities where there high level precipitation. The evidence limited, partly due data limitations. We used crowdsourced (taken from Strava activity-tracking app) fixed-effects panel regression models...
Abstract The benefits of cycling have been well established for several decades. It can improve public health and make cities more active environmentally friendly. Due to the significant net benefits, many local governments in Scotland promoted cycling. Glasgow City Council constructed four pieces infrastructure between 2013 2015, partly preparation 2014 Commonwealth Games encourage generally. This required substantial capital investment. However, effectiveness these big new investments has...
The UK government introduced strict measures (including asking people to work from home and a lockdown) slow the spread of COVID-19 by limiting people’s movement. This led substantial reductions in traffic, making roads much safer for cyclists. provides unique opportunity study role played safe cycling infrastructure. Many cities have provided infrastructure improve safety encourage cycling. However, access varies across neighbourhoods, potentially contributing inequality. Since became due...
Emerging forms of mobile phone data generated from the use applications have potential to advance scientific research across a range disciplines. However, there are risks regarding uncertainties in socio-demographic representativeness these data, which may introduce bias and mislead policy recommendations. This paper addresses issue directly by developing novel approach assessing representativeness, demonstrating this with two large independent application datasets, Huq Tamoco, each three...
Compact development is often recommended to reduce auto-dependency thereby decreasing related energy consumptions and transportation emissions. However, there could be a non-linear relationship between density emissions because of possible association vehicle miles travelled (VMT); low travel speed due congestion; the neighborhood characteristics (e.g., type age). In addition, self-selection issue can exist in land use-transportation analysis are estimated based on behavior. Using 2006 Puget...
The present research examines the role of maths-related literacies, or competencies, in influencing relationship between ICTs and travel behaviour. We adopted a Bayesian approach to jointly model frequency different types internet use, total distance per traveller, with respect measures lifewide literacies (other than reading), specifically form numeracy financial literacy questions. Our findings revealed that participants higher levels these used more frequently, travelled further those...
Worldwide bike-sharing systems are growing in popularity as an alternative, environmentally friendly mode of transportation. As cities seek to further develop programmes, it is important consider how should expand simultaneously address existing inequalities accessibility, and best serve demand. In this paper, we determine ideal locations for future stations Glasgow, Scotland, by integrating demand modelling with accessibility considerations. We began analysing the spatio-temporal trends...
Adaptive traffic signal control (ATSC) is an effective method to reduce congestion in modern urban areas. Many studies adopted various approaches adjust plans according real-time response demand fluctuations improve network performance (e.g., minimise delay). Recently, learning-based methods such as reinforcement learning (RL) have achieved promising results plan optimisation. However, adopting these self-learning techniques future environments the presence of connected and automated...
Planning for cycling is often made difficult by the lack of detailed information about when and where takes place. Many have seen arrival new forms data such as crowdsourced a potential saviour. One key challenges posed these understanding how representative they are population. To address this challenge, limited number studies compared to ground truth counts. In general, found high correlation over long run but with geographic coverage, counters placed on routes already known be popular...
The role of cycling has become more important in the urban transport system during Covid-19 pandemic. As public passengers have tried to avoid crowded vehicles due safety concerns, a rapid surge activities been noted many countries. This implies that cyclists might be exposed air pollution, potentially leading health problems cities like Seoul where level pollution is high.We utilised three years bike sharing programme (Ddareungi) data and time series models examine changes relationship...
This UK-focused longitudinal study examines the influence of maternal past non-transport, pro-environmental actions (e.g. eco-friendly shopping and energy-saving behaviours during their children's adolescence) on sustainable transport as young adults. It also explores role attitudes adults in this influence. Structural equation modelling was used to explore these complex interactions based data from 977 mother–child pairs waves 4 10 UK Household Longitudinal Study. Findings reveal that...
The effects of information and communications technologies (ICT) on mobility have been investigated for several decades; however, few studies focused the amount time spent using ICT, its implications travel behavior, how such relationships may vary with characteristics residential location. This study focuses Internet use nonwork purposes two research questions are examined: Does affect motorized trip generation distance? How do these according to location as urban, town, rural areas where...
We describe the Integrated Multimedia City Data (iMCD), a data platform involving detailed person-level self-reported and sensed information, with additional Internet, remote sensing, crowdsourced environmental sources that measure wider social, economic physical context of participant. Selected aspects platform, which covers Glasgow, UK, city-region, are available to other researchers, allows knowledge discovery on critical urban living themes, for example in transportation, lifelong...
New technologies have significant effects on travel behavior, attitudes, habits and potentially future demand. Effects may be more prominent for Millennials. Little empirical research has investigated these relationships, mainly due to data limitations. This study focuses the potential influence of using Internet while traveling Millennials’ plans car ownership. We examine two questions: Does trip frequencies? it affect intention purchase a car? Results suggest that use is positively...
This study takes the 39-day Glasgow Subway closure in July 2016 as a natural experiment to evaluate effect of subway on bike-sharing trips. We find that trips increased by 20.7% for incoming and 20.1% outgoing average each bike station proximity during suspension. Some this change persisted, with 12.4% remaining after resumption service. Our findings suggest first, are substitutes; second, temporary service disruption was not enough break commuters' long-term habits, third, diversion factors...
