I had the opportunity to present in Manly earlier today to GPT, an Australian property company, about The Future of Transport and Access. (I also had the opportunity to ride the Manly Fast Ferry, twice!) Actually, I gave the talk 4 times to 4 different groups, as they had the attendees shop around at the marketplace of ideas (it was a regulated marketplace). They had an artist draw my talk (once), which is below.
Inequality in transport provision is an area of growing concern among transport professionals, as it results in low-income individuals travelling at lower speeds while covering smaller distances. Accessibility, the ease of reaching destinations, may hold the key in correcting these inequalities through providing a means to evaluate land use and transport interventions. This article examines the relationship between accessibility and commuting duration for low-income individuals, compared to the general population, in three major Canadian metropolitan regions, Toronto, Montreal, and Vancouver using multilevel mixed effects statistical models for car and public transport commuters separately. Accessibility measures are generated for jobs and workers both at the origin (home) and the destination (place of work) to account for the impact of competing labor and firms. Our models show that the impacts of accessibility on commuting duration are present and stronger for low-income individuals than for the general population, and the differences in impact are more visible for public transport commuters. The results suggest that low-income individuals have more to gain (in terms of reduced commute time) from increased accessibility to low-income jobs at the origin and to workers at the destination. Similarly, they also have more to lose from increased accessibility to low-income workers at the origin and to low- income jobs at the destination, which are proxies for increased competition. Policies targeting improvements in accessibility to jobs, especially low-income ones, by car and public transport while managing the presence of competition can serve to bridge the inequality gap that exists in commuting behavior.
Improving accessibility is a goal pursued by many metropolitan regions to address a variety of objectives. Accessibility, or the ease of reaching destinations, is traditionally measured using observed travel time and has of yet not accounted for user satisfaction with these travel times. As trip satisfaction is a major component of the underlying psychology of travel, we introduce satisfaction into accessibility measures and demonstrate its viability for future use. To do so, we generate a new satisfaction-based measure of accessibility where the impedance functions are determined from the travel time data of satisfying trips gathered from the 2017/2018 McGill Transport Survey. This satisfaction-based measure is used to calculate accessibility to jobs by four modes (public transport, car, walking, and cycling) in the Montreal metropolitan region, with the results then compared to a standard gravity-based measure of accessibility. We then offer a dissatisfaction index where we combine the ratio between satisfaction-based and gravity-based accessibility measures with mode share data. This index highlights areas with potentially high proportions of dissatisfied commuters and where interventions for each mode could have the highest impacts on the quality of life of a given mode commuter. Such analysis is then combined with a vulnerability index to show the value of this measure in setting priorities for vulnerable groups. The study demonstrates the importance of including satisfaction in accessibility measures and allows for a more nuanced interpretation of the ease of access by researchers, planners, and policy-makers.
This study explores the relationship between transit-based job accessibility and minority races and ethnicities, low- and middle-income households, and carless households at the block group level for the 50 largest by population metropolitan regions in the United States. A log-linear regression model is used to identify inequities in transit-based job accessibility across the US using data collected from the American Community Survey, the Environmental Protection Agency’s Smart Location Database, and the Access Across America database. The intra-metropolitan analyses reveal that accessibility is unevenly distributed across block groups that have different densities of race and levels of income. The differences in accessibility are especially apparent where there are denser pockets with higher percentages of African Americans, Hispanics, low-income households, and zero-car households. The inter-metropolitan analyses show that accessibility is unevenly distributed across metropolitan regions across the US when considering various sociodemographic populations. Different metropolitan regions provide different levels of accessibility for all investigated sociodemographic categories, whether considering racial minorities, levels of income, or car ownership. The results may inform recommendations for equitable transport planning and policy-making.
Accessibility is often not a performance measure for transit services. This study is conducted following the introduction of new timetables which intended to improve passenger throughput for Sydney’s transit services, but resulted in major delays experienced by passengers thereafter. Accessibility at 30-minute travel threshold before and after the timetable change are calculated between 8 to 9 am, to measure accessibility benefits, if any, from the new timetable. The results show a lack of systematic improvement by the new table, and downgrade of accessibility on average. The overall person-weighted accessibility dropped by 3%, from 45,070 to 43,730, and 63.3% of the population’s access to jobs would be adversely affected after its implementation. This study advocates for the inclusion of accessibility metrics into transit performance measures to connect with people who use transit.
Transport policy decision follow from application of rules and standards. To the dismay of many in the transport community, these standards often come from another time with different values, including US documents such as:
ITE’s Trip Generation Manual
AASHTO’s Green Book
TRB’s Highway Capacity Manual
While those aren’t going to change overnight, new preferences can be documented and embedded if they too become standards.
One of the key problems is what to value when investing in transport or regulating land development. Readers of this blog will likely prioritize accessibility — the ease of reaching valued destinations. This connects transport and land use, considering both how easy it is to move and where things are located. While many planners know how to measure this, many don’t, and all could benefit from standardizing application to best practice.
To that end, I think we need a working group to develop such a standard, which would clarify topics like how to measure, how to compute, how to present, and what to consider. Let me know if you are interested, and I will add you to a mailing list to discuss this. I hope there can be a meeting at TRB in DC in January.
which garnered many likes. But of course Twitter is no place to have a discussion like this. So
This is what I am thinking:
Journal Name: Transport Findings
Open Access. Flat $50 fee payable on submission (with no guarantee of acceptance) and $50 payable on acceptance. This filters the cranks, covers limited typesetting, article charges, hosting, etc. See Scholastica website for their costs, (the platform looks good for this) if I read it right, this price would more or less cover fixed costs if we had 50 articles per year. This handbook is also of interest
Maximum word count of 1000 (including References). Maximum Figure count of 3, Table count of 3.
The new journal would not be affiliated with existing journals (this creates confusion on the part of authors and reviewers).
Peer Review by 1 Reviewer drawn from the Editorial Advisory Board. (We add to the EAB if we cannot find someone who can review the article). Everyone who has reviewed in the past 3 years stays on the EAB. The Review should be done in 1 month. So while the Review is anonymous, the reviewers overall are all known.
Articles must be either New Question, New Method, New Data, or New Finding (i.e. it can almost exactly replicate a previous study and find something different), or some combination of the above.
The acceptance test is whether it satisfies the above and appears scientifically correct (no obvious mistakes/flaws) and replicable, and quality of English.
The journal has Accept/Reject decisions only. (Obviously people can submit again if they want to change the manuscript, however NEW submission, NEW reviewer, NEW fee). Acceptance Letters can add some minor comments. No Revise & Resubmit.
Scope: Findings in the broad field of transport
All data must be publicly available if possible (goes to replicability, caveats for personally identifying information)
No special issues, themes, or anything like that, the journal is basically just a list of peer-reviewed short articles in reverse chronological order.
There is a standard template for article submission, (I would say a web form, but that can’t handle equations, figures, or tables well). something like
AUTHORS (NAME, AFFILIATION, CONTACT)
1. QUESTION AND HYPOTHESES
2. METHODS AND DATA
No sections titled: Intro, No Lit Review, No Theory, No Discussion, No Conclusions
Comments on Twitter, I guess.
Now I am not thinking I should run this journal (I already have my hands full), but that it should exist. I am happy to help if someone has the energy to organize it. It should be fairly straight-forward and mostly self-organizing to the point of being self-sustaining, but it does need an initial investment of energy to get there.
The Transport Research Association for NSW (TRANSW) is a new joint initiative of the University of Sydney, University of New South Wales (UNSW), University Technology, Sydney (UTS), and Transport for New South Wales (TfNSW). It aims to foster and support cross-disciplinary and cross-institutional transport research and practice. For more information, please visit transw.org.au. TRANSW will be launched this year and its Inaugural Symposium will be held in Sydney CBD on Thursday 15 November 2018. Please save the date!
The annual Symposium provides a platform for transport research students, academics, and practitioners to discuss relevant topics in transport. Research students will have the opportunity to showcase their research and attendees will have the opportunity to meet transport students, academics, and practitioners in an informal setting.
The Symposium will be organised each year by one of the participating universities. The Inaugural Symposium on 15 November 2018 is organised and sponsored by the University of Sydney and registration is available free of charge for researchers in transport from the three participating universities as well as for transport experts at Transport for NSW. Personal invitations will be sent by email on 15 October 2018.
