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 network development on community perception of place quality. This study contributes to the literature by presenting the results of 601 completed questionnaires investigating variation in perception of place quality between legacy and modernised tram streetscapes in Melbourne, Australia. Evidence demonstrates that modernised tram streetscapes were perceived to contain an enhanced physical design compared to their legacy counterparts. Additionally, modernised tram streetscapes were rated as higher quality locations overall that were more likely to facilitate a wide range of place-based activities and amenities. Overall findings provide evidence that tram modernisation can be framed as an opportunity for place quality enhancements, and appear to contradict some of the political complications that have played a role in stalling tram streetscape modernisation projects in Melbourne.

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 paper assesses how such variations affecting new residential apartment development in Melbourne, known locally as parking overlays, compare against residential parking demand. Using household car ownership data as a proxy for off-street residential parking demand, a case-control analysis was undertaken to compare car ownership within and immediately outside areas affected by the parking overlays, while controlling for a range of built environment, public transport, demand management and socio-demographic variables. Key findings indicate that car ownership is generally lower in areas affected by parking overlays, yet this was either roughly the same or well below the actual parking requirement. Through regression modelling, the results highlighted the importance of public transport service quality, car parking requirements and demographics in influencing car ownership within and immediately outside the parking overlay areas. These results were used to develop a parking overlay index to identify other areas that could benefit from more flexible residential parking requirements. Despite parking overlays considered as a form of parking management, the results imply that, in Melbourne, they represent little more than a conventional supply-side approach to parking policy. The results indicate that residential off-street parking requirements could be reduced further in Melbourne, both within and outside of areas affected by parking overlays, to more actively manage parking demand.

This research aims to contribute to understanding the range of site characteristics that are associated with multi-modal trip generation rates at residential developments. Data was extracted from the Trip Rate Information Computer System (TRICS) database for 933 residential developments in the United Kingdom and Ireland, with trip generation rates estimated separately for person, vehicle, public transport, pedestrian and bicycle trips. A total of 65 independent variables were included in the analysis, representing a range of site characteristics relating to location and housing attributes, public transport service quality, parking and travel plan measures. Trip generation rates by mode and time period were then regressed against the site characteristics to explore their association with multi-modal trip generation. Key findings showed that multi-modal trip generation rates are associated with a range of site characteristics at residential developments. These include, to varying degrees, locational and housing attributes such as apartment developments and housing size, population density, car ownership, distance to local facilities such as the nearest local/corner shop, public transport service quality, on-site parking spaces/dwelling, plus various travel plan initiatives such as secure well-lit/covered cycle parking. The results imply that various site characteristics deserve greater consideration in establishing multi-modal trip generation rates and that characteristics that support travel by non-vehicle modes should be incorporated within new residential developments where possible.

New development in greenfield areas generally requires new infrastructure. To assist with funding this infrastructure, development contributions are increasingly used. Mostly, contributions are collected for local trunk infrastructure, but regional and state infrastructure for transport, health and other purposes is also needed. The Growth Area Infrastructure Contribution (GAIC) in Melbourne, Australia, is an example of a charge that is specifically collected for state-funded infrastructure. Building on previous research, this article explores the extent to which the GAIC reflects good practice and discusses idiosyncrasies and opportunities for improvement, in view of similar contribution schemes elsewhere, e.g. in New South Wales.

Ensuring a high level of customer satisfaction with public transport is a key objective for transit agencies wishing to maintain and/or increase service uptake. Importance – Performance Analysis (IPA) can be used to identify gaps in the performance of public transport service attributes relative to their importance. However, this approach is often used without adequate consideration of its validity or reliability. Using a case study of bus services in Tehran, Iran, this paper contributes to the literature by improving the validity and reliability of IPA through: incorporating Exploratory Factor Analysis (EFA) to identify key components of bus service attributes, proposing a method for prioritising attributes, introducing confidence intervals around each attribute to aid in the interpretation of results, and dividing the sample using Cluster Analysis (CA) to mitigate the effects of heterogeneity on the results. The performance and importance of 15 different bus service attributes was assessed through a survey of 390 bus passengers conducted at six high-traffic bus terminals in Tehran. EFA results showed that the bus attributes could be represented by four key components: convenience, comfort, reliability and security. CA results classified the sample into three clusters based on socio-demographic and bus travel characteristics. IPA results indicated that transit agencies and policy-makers need to give greater attention to improving comfort related attributes of bus services in Tehran such as ventilation, cleanliness of buses, and providing facilities for elderly/disabled people. The enhanced approach to IPA developed in this paper can be applied to other jursidictions where agencies are seeking to identify areas to improve public transport customer satisfaction.

The number of elderly people as a proportion of the world’s population is growing significantly. Special attention to the accessibility and mobility requirements of this group is needed. The contribution of this paper is a review of travel patterns, mode preferences, infrastructure solutions, accessibility indices, mode choice models and datasets as they relate to elderly mobility. Key findings highlight the role of residential location characteristics in shaping elderly travel patterns, helping to explain why research on elderly travel has largely relied on case studies to date. The review also summarizes a range of indices that have been developed to measure public transport and walking accessibility among the elderly, including distance and time-based methods. Future research should consider the dominance of private transport in facilitating elderly mobility and its implications for cities experiencing an aging population.

Travel plans, also known as transportation demand management (TDM) plans, can be required through the planning approval process for new developments. Where decisions on development applications are appealed, a planning tribunal may review the decision, including the requirement for a travel plan. This research aimed to explore planning tribunal decisions on travel plans for new developments. Using a case study of Victoria, Australia, an analysis of 178 planning tribunal reports from 2005–16 showed that travel plan requirements were accepted in 88% of cases. Larger planning tribunal groups were found to be associated with higher acceptance of travel plan requirements. Travel plan requirements with more prescriptive/tailored wording were over 20 times more likely to be accepted compared to those with generic wording. Recommendations for improving practice include the development of more clearly worded travel plan conditions, provision of training programs and guidelines, and the introduction of supportive planning policy.

Planning policies support the development of healthy, liveable cities. Yet, recent research suggests they may not offer enough detail to provide on-the-ground delivery of social and transport infrastructure that supports and impacts healthy, active behaviours and the subjective wellbeing of residents in new developments and growth areas. Three analyses were conducted. First, planning policies were reviewed using a content analysis to identify environmental features known to support healthy and active behaviours. Then, for two growth area estates located in Melbourne, Australia (Allura and Selandra Rise), the on-the-ground delivery of these planning policies were evaluated using spatial data of key destinations (e.g., shops, schools, and transport) and geographic information systems analysis. Finally, the health and subjective wellbeing of adult residents from these two estates combined (n = 352) was assessed using survey methodology. This included asking residents about the importance and satisfaction with access to transport and key destinations. We found that many built environment features were mentioned in the policy documents; however policy standards for dwelling density remain low at 15 dph and distances for accessing activity centres too long at 1 km to adequately support the walkability of new growth areas. We found generally, that average distances to key destinations were longer and more variable in growth areas in comparison to inner city areas and Greater Melbourne overall. For residents, satisfaction with access to destinations differed between the two case study areas. Residents in Allura, where destination and transport access was generally poorer were less satisfied, whilst those in the more walkable and established Selandra Rise area were more satisfied. Although planning policies support the development of active transport and healthy, liveable cities they are insufficient for influencing healthy behaviours when not well implemented. Early delivery of social and transport infrastructure and services must occur early in the development cycle of new growth areas to support healthier and more sustainable behaviours.

Turn signal neglect is considered to be a key contributor to crashes at intersections, yet relatively little research has been undertaken on this topic, particularly in developing countries. Using a case study of Vietnam, this research aimed to explore the role of environmental characteristics, perceived risk, beliefs and lifestyle behaviours on the frequency of turn signal use at intersections. A self-administered questionnaire was distributed to motorcyclists (n = 527) and car drivers (n = 326) using online and offline methods. Using partial least squares structural equation modelling (PLS-SEM), key findings indicate that perceived risk, beliefs and environmental characteristics play a significant role in affecting the frequency of turn signal use among motorcycle riders and car drivers at intersections. While lifestyle behaviours were not found to be a good predictor of turn signal use among car drivers, they were found to indirectly affect turn signal use among motorcycle riders through the mediation of beliefs and perceived risk. The findings can help inform the development of more targeted measures to increase turn signal use.

Mobile phone use while driving presents significant risks, potentially leading to injury or death through distracted driving. Using a case study of Vietnam, this research aimed to understand the effect of problematic mobile phone use (also known as mobile phone addiction or compulsive mobile phone use), attitudes and beliefs, and perceived risk on the frequency of mobile phone use among motorcyclists and car drivers. A self-administered questionnaire was distributed to motorcyclists (n1= 529) and car drivers (n2= 328) using an online survey and face-to-face survey. The survey took around 20-min to complete and participants were entered into a lottery for supermarket vouchers. Of the motorcyclists, 42% of the sample (the highest proportion) was in the 18-25 age group while the 36-45 age group accounted for the highest proportion among car drivers (34.8%). Using structural equation modelling (SEM), key findings showed that each construct influenced mobile phone use, but in different ways for motorcycle riders and car drivers. Attitudes and beliefs had the largest effect on mobile phone use while riding among motorcyclists, with problematic mobile phone use having the smallest influence. In contrast, problematic mobile phone use had the largest effect on mobile phone use while driving a car, with attitudes and beliefs having the smallest effect. The findings of this study point to the need for tailored interventions involving a range of actors (policymakers, police enforcement, mental health professionals, advocacy groups and the wider community) to raise awareness, modify attitudes and increase risk perception associated with mobile phone use while driving/riding. This can be achieved thorough educational tools and road safety campaigns which are focused on reducing this risky driving behaviour. This includes customising road safety programs for individuals and groups affected by problematic mobile phone use such as targeted advertising.

Public transport (PT) influences the urban road system in many ways, including traffic congestion, environment, society, safety and land use impacts. While there are many studies focusing on the benefits of PT, research on congestion impacts, a fundamental component of any analysis of transport performance, associated with PT has received little attention. This paper aims to review the traffic congestion impacts of PT and how they are assessed. Traffic congestion is most commonly related to vehicle travel; yet, the real measure of congestion in transport systems is people travel. This paper looks at the appropriateness of existing traffic congestion measures and how suitable they are for measuring the impact of an existing PT system in the short-term. The literature review indicates that most studies relating to the congestion impacts of PT have used vehicle-based congestion measures. People-based measures may be more appropriate in assessing PT impacts. The paper also proposes a new framework for looking at the short-term effects of an existing PT system on traffic congestion. It suggests a few areas where further work can be undertaken to improve our understanding of traffic congestion incorporating PT such as exploring the mode shift from PT to car, estimating network-wide PT congestion creation impacts and determining the net congestion impact of PT.

Public transport customer amenities cover a range of measures that can enhance the quality of the passenger experience, such as information provision and station quality. While much research has determined the value that users place on amenities, there is little understanding of current practice in the use of customer amenity valuations in project appraisal. A survey of transit agencies in 11 cities (Melbourne, Sydney, Brisbane, Perth, Auckland, London, Paris, Toronto, Vienna, Oslo and Singapore) was undertaken showing that Australasian cities, albeit Melbourne, generally have widespread inclusion of customer amenities as part of advanced appraisals for all relevant types of public transport projects. Australasian practice tends to include customer amenities more frequently in project appraisal than London, Singapore and Oslo. Paris, Toronto and Vienna, although they adopt advanced appraisals for some projects, rarely (if at all) include customer amenities in these appraisals. While agencies generally use published sources of customer amenity values specific to their country, Toronto and Singapore tend to use customer amenity values from London, highlighting a lack of local customer amenity values.

This paper explores the extent to which high quality public transport can support reduced car parking requirements for new residential apartment buildings. Using a case study of Melbourne, the demand for car parking at residential apartment buildings in proximity to high frequency public transport is assessed, while controlling for a range of socio-demographic, urban design and demand management variables. Key findings indicate that while lower demand for car parking is associated with proximity to high quality public transport, this association is not significant when controlling for other factors that influence car ownership. Public transport service supply within 800 m of residential apartment buildings was instead found to be significant, rather than simple distance to transit. Modelling results suggest an inelastic relationship whereby a 10% increase in public transport service supply is associated with a 0.9–1.2% reduction in car parking demand as measured by levels of car ownership. Notwithstanding broader criticisms of residential off-street parking minimums, the findings have important implications for the development of residential car parking policies, suggesting that city-wide car parking requirements should appropriately reflect the spatial distribution and quality of public transport services.

Motorcycle taxis play an important role in many developing countries, particularly in servicing areas where conventional public transport is not available. This form of transport has become more popular in recent years since online ride-hailing companies launched motorcycle taxi services. However, little is known about traffic crash risks among app-based motorcycle taxi riders. This study therefore aimed to investigate the prevalence and factors associated with road traffic crashes among app-based motorcycle taxi riders. A field survey and online survey were undertaken to obtain information about riders’ socio-demographics, work patterns, travel behaviour and crash involvement. A total of 602 valid survey responses from riders were obtained across three cities in Vietnam, including 571 males and 31 females. The overall reported prevalence of road traffic crashes among app-based motorcycle taxi riders over a one-year period was 30%. Binary logistic regression modelling showed that traffic crashes were associated with non-students, low education levels, high daily travel distances, regular smoking, and using a mobile phone while driving. Despite regulation of online ride-hailing motorcycle taxi services in Vietnam, the reported prevalence of crashes among riders is considered to be relatively high. Targeted interventions to reduce the risk of being involved in a crash should be considered, such as increasing road safety education for non-student riders and imposing a daily travel distance limit for riders.

Turn signal neglect is a major cause of traffic crashes, particularly rear-end collisions. However, little research has investigated the use of turn signals among motorists, particularly in developing countries with high levels of motorcycle use. This research aimed to investigate the prevalence and factors associated with turn signal use at intersections among car drivers and motorcyclists in Da Nang, Vietnam. Cross-sectional roadside observations were undertaken at 24 sites across Da Nang City during weekday and weekend periods. A total of 17,142 vehicles were observed, including 2392 cars and 14,750 motorcycles. Turn signal use among car drivers (68.27%) was found to be significantly higher than motorcyclists (40.13%). Binary logistic regression modelling showed that turn signal neglect at intersections was associated with making a right turn, not carrying passengers, travelling outside of the city centre, travelling on weekdays, and the absence of separate car lanes, pedestrian crossings and traffic lights. Despite national legislation regulating turn signal use in Vietnam, the use of turn signals is relatively low compared with developed countries. The findings highlight the need for both greater and more targeted enforcement of existing legislation combined with extensive road safety education.

Trip generation estimates are integral to assessing the transport impacts of land use developments. However, past efforts have predominantly focused on vehicle trips only. This paper provides an international literature review of multimodal trip generation associated with land use developments. A total of 153 publications were sourced as relevant to the review. The results show that although multimodal trip generation studies have been relatively scant, they have received greater attention in the last 10 years. A range of issues was identified with estimating and applying multimodal trip generation rates, not least was a lack of sufficient data and higher complexity in data collection compared with vehicle trip generation studies. Current knowledge gaps highlight opportunities to move toward greater international coordination and sharing of multimodal trip generation data, along with exploring the use of technology to assist with data collection. Key directions for the future include a fundamental change in paradigm to consistently account for multimodal trip generation, the development of an international multimodal trip generation database, and greater sensitivity testing in assessing the multimodal impacts of new land use developments.

Objective: Motorcycle crashes are a significant road safety challenge, particularly in many low- and middle-income countries where motorcycles represent the vast majority of their vehicle fleet. Though risky riding behaviors, such as speeding and riding under the influence of alcohol, have been identified as important contributors to motorcycle crashes, little is understood about the effect of using a mobile phone while riding on motorcycle crash involvement. This article investigates crash involvement among motorcycle riders with risky riding behaviors, particularly using a mobile phone while riding. Methods: Data were obtained from an online survey of university students’ risky riding behaviors in Vietnam administered between March and May 2016 (n = 665). Results: Results show that 40% of motorcycle riders reported to have experienced a crash/fall and nearly 24% of motorcycle riders indicated that they had been injured in a crash/fall. Effects of mobile phone use while riding on safety of motorcycle riders are highlighted. Specifically, more frequent use of a mobile phone for texting or searching for information while riding is associated with a higher chance of being involved in a crash/fall. The results also show that drink riding is associated with a higher chance of being injured. Conclusions: Overall this article reveals significant safety issues of using a mobile phone while riding a motorcycle, providing valuable insight for designing education and publicity campaigns.

Mode shift from public transport (PT) to private car in the event of PT withdrawal can increase the level of traffic congestion in urban areas. This increase in congestion is interpreted as the congestion relief impact associated with urban PT. However, existing methods for estimating the impact of PT on relieving traffic congestion have generally assumed a fixed mode shift to car. This paper presents an enhanced method for estimating the congestion relief impact of PT by varying the mode shift to car. First, primary data from a survey conducted in Melbourne, Australia was used to develop a linear regression model for predicting the share of mode shift from PT to car. The Victorian Integrated Survey of Travel and Activity (VISTA) dataset was then applied to this model to estimate the potential mode shift for different spatial areas of Melbourne. Second, PT congestion relief impacts were estimated by contrasting the level of congestion in two scenarios: ‘with PT’ and ‘without PT’. This stage was undertaken using the Victorian Integrated Transport Model (VITM), a conventional four step model. The results show that PT operations in Melbourne contribute to reduce the number of severely congested links by more than 63%. Vehicle time travelled and total delay on the road network also reduces by around 56%.

Motorcyclist safety is a major concern in many developing countries. Understanding motorcycle riders’ risky behaviours, particularly among the younger population, is essential to developing effective interventions. This paper explores the correlations between mobile phone use while riding and other risky riding behaviours as well as the relationships between perceived risks and risky riding behaviours, using an online survey of university students in Vietnam. Results show that calling while riding a motorcycle had the highest prevalence (74%) while reckless overtaking had the lowest prevalence (33.2%). Survey participants who indicated that they had the behaviours of reckless overtaking or riding on sidewalks were around twice as likely to call, text, or search for information while riding. In addition, those who admitted that they rode a motorcycle while under the influence of alcohol were nearly twice as likely to call or text while riding. The results also show that perceived crash risks reduced the likelihood of risky riding behaviours, including calling, texting, searching for information, speeding, running red lights, riding on the wrong side of a road, and riding on sidewalks. A more coordinated approach to enforcement is needed to help reduce the prevalence of multiple risk taking behaviours among motorcyclists.
