Assessing the cost of transfer inconvenience in public transport systems: A case study of the London Underground

Assessing the cost of transfer inconvenience in public transport systems: A case study of the London Underground
Transportation Research Part A: Policy and Practice, Vol. 45, 2, 91-104

Guo, Zhan and Nigel H.M. Wilson

Few studies have adequately assessed the cost of transfers in public transport systems, or provided useful guidance on transfer improvements, such as where to invest (which facility), how to invest (which aspect), and how much to invest (quantitative justification of the investment). This paper proposes a new method based on path choice,3 taking into account both the operator's service supply and the customers' subjective perceptions to assess transfer cost and to identify ways to reduce it. This method evaluates different transfer components (e.g., transfer walking, waiting, and penalty) with distinct policy solutions and differentiates between transfer stations and movements.

The method is applied to one of the largest and most complex public transport systems in the world, the London Underground (LUL), with a focus on 17 major transfer stations and 303 transfer movements. This study confirms that transfers pose a significant cost to LUL, and that cost is distributed unevenly across stations and across platforms at a station.

Transfer stations are perceived very differently by passengers in terms of their overall cost and composition. The case study suggests that a better understanding of transfer behavior and improvements to the transfer experience could significantly benefit public transport systems.

How people leave a devastated area after a disaster is critical to understanding their ability to cope with risks they face while evacuating. Knowledge of their needs for communications about these risks is particularly crucial in planning for emergency responses. A convenience sample of 1,444 persons who survived the World Trade Center (WTC) attacks on September 11, 2001 were surveyed to ascertain their initial and ultimate destinations once they had left the buildings, how they arrived there, the role of types of obstacles they encountered, and the need for information and the seeking of other people as potential factors in influencing the process of leaving immediately. This survey was part of a larger, original survey. Results showed differences in how people traveled by mode to initial and ultimate destinations, how immediately they left the area, and factors associated with when they left. How they traveled and when they left were associated with where people lived, their tendency in times of stress to seek out other people including who they knew in the immediate area (e.g., co-workers or friends), the physical conditions surrounding them, and the importance to some of waiting for more information. Many people indicated they did not leave immediately because they had no information about where to go or what services would be available to them. Perceptions and communications about risks they were facing were reflected in the choices they considered in how and when to leave the area. These findings have numerous ramifications for understanding and guiding personal behavior in catastrophic situations.

Consumer Estimation of Recommended and Actual Calories at Fast Food Restaurants

Consumer Estimation of Recommended and Actual Calories at Fast Food Restaurants
Obesity (Silver Spring). Oct 2011; 19(10): 1971–1978.

Elbel, B.

Recently, localities across the United States have passed laws requiring the mandatory labeling of calories in all chain restaurants, including fast food restaurants. This policy is set to be implemented at the federal level. Early studies have found these policies to be at best minimally effective in altering food choice at a population level. This paper uses receipt and survey data collected from consumers outside fast food restaurants in low-income communities in New York City (NYC) (which implemented labeling) and a comparison community (which did not) to examine two fundamental assumptions necessary (though not sufficient) for calorie labeling to be effective: that consumers know how many calories they should be eating throughout the course of a day and that currently customers improperly estimate the number of calories in their fast food order. Then, we examine whether mandatory menu labeling influences either of these assumptions. We find that approximately one-third of consumers properly estimate that the number of calories an adult should consume daily. Few (8% on average) believe adults should be eating over 2,500 calories daily, and approximately one-third believe adults should eat lesser than 1,500 calories daily. Mandatory labeling in NYC did not change these findings. However, labeling did increase the number of low-income consumers who correctly estimated (within 100 calories) the number of calories in their fast food meal, from 15% before labeling in NYC increasing to 24% after labeling. Overall knowledge remains low even with labeling. Additional public policies likely need to be considered to influence obesity on a large scale.

Urban Aging, Social Isolation, and Emergency Preparedness

Urban Aging, Social Isolation, and Emergency Preparedness
IFA Global Ageing Vol. 6 Issue 2, p39

Gusmano, M.K & Rodwin, V.G.

The article presents a review of an individual approach to emergency preparedness for socially isolated elderly city dwellers. It cites crisis instances highlighting older persons' vulnerability and the importance of neighborhood characteristics as the isolated elderly had reportedly higher mortality rates in poor neighborhoods and abandoned lots than in equally poor but more socially-connected neighborhoods. It suggests a population-based case management requiring information dissemination and outreach strategies for finding and assisting older persons.

The Rise and Fall of a Micro-Learning Region: Mexican Immigrants and Construction in Center-South Philadelphia

The Rise and Fall of a Micro-Learning Region: Mexican Immigrants and Construction in Center-South Philadelphia
2010. Environment and Planning A, Volume 42, Number 7

Iskander, Natasha, Nichola Lowe, and Christine Riordan

This paper documents the rise and fall of a micro-learning region in Philadelphia. The central actors in this region are undocumented Mexican immigrants who until recently were able to draw on the intensity of their workplace interactions and their heterodox knowledge to produce new and innovative building techniques in the city's residential construction. The new knowledge they developed was primarily tacit. More significantly, the learning practices through which immigrant workers developed skill and innovated new techniques were also heavily tacit. Because these practices were never made formal and were never made explicit, they remained invisible and difficult to defend. With the housing market collapse and subsequent decline in housing renovation in south-center region of Philadelphia, this tacit knowledge and the practices that gave it shape and significance, are no longer easily accessible. We draw on this case to demonstrate the importance of access to the political and economic resources to turn learning practices into visible structured institutions that protect knowledge and skill. Whether or not the practices that support knowledge development are themselves made explicit can determine whether the knowledge they produce becomes an innovation that is recognized and adopted or whether it remains confined to a set of ephemeral practices that exist only so long as they are being enacted.

Hospital Performance, the Local Economy, and the Local Workforce: Findings from a US National Longitudinal Study

Hospital Performance, the Local Economy, and the Local Workforce: Findings from a US National Longitudinal Study
PLoS Med 7(6): e1000297. doi:10.1371/journal.pmed.1000297

Blustein, J., Borden, W.B., Valentine, M.


Background: Pay-for-performance is an increasingly popular approach to improving health care quality, and the US government will soon implement pay-for-performance in hospitals nationwide. Yet hospital capacity to perform (and

improve performance) likely depends on local resources. In this study, we quantify the association between hospital performance and local economic and human resources, and describe possible implications of pay-for-performance for socioeconomic equity.

Methods and Findings: We applied county-level measures of local economic and workforce resources to a national sample of US hospitals (n = 2,705), during the period 2004–2007. We analyzed performance for two common cardiac conditions (acute myocardial infarction [AMI] and heart failure [HF]), using process-of-care measures from the Hospital Quality Alliance [HQA], and isolated temporal trends and the contributions of individual resource dimensions on performance, using multivariable mixed models. Performance scores were translated into net scores for hospitals using the Performance Assessment Model, which has been suggested as a basis for reimbursement under Medicare’s ‘‘Value-Based Purchasing’’ program. Our analyses showed that hospital performance is substantially associated with local economic and workforce resources. For example, for HF in 2004, hospitals located in counties with longstanding poverty had mean HQA composite scores of 73.0, compared with a mean of 84.1 for hospitals in counties without longstanding poverty (p,0.001). Hospitals located in counties in the lowest quartile with respect to college graduates in the workforce had mean HQA composite scores of 76.7, compared with a mean of 86.2 for hospitals in the highest quartile (p,0.001). Performance on AMI measures showed similar patterns. Performance improved generally over the study period. Nevertheless, by 2007—4 years after public reporting began—hospitals in locationally disadvantaged areas still lagged behind their locationally advantaged counterparts. This lag translated into substantially lower net scores under the Performance Assessment Model for hospital reimbursement.

Conclusions: Hospital performance on clinical process measures is associated with the quantity and quality of local economic and human resources. Medicare’s hospital pay-for-performance program may exacerbate inequalities across regions, if implemented as currently proposed. Policymakers in the US and beyond may need to take into consideration the balance between greater efficiency through pay-for-performance and socioeconomic equity.

Economic Development Impacts of High-speed Rail

Economic Development Impacts of High-speed Rail
RCWP 10-007 June, 2010

Levinson, David

High-speed rail lines have been built and proposed in numerous countries throughout the world. The advantages of such lines are a higher quality of service than competing modes (air, bus, auto, conventional rail), potentially faster point-to-point times depending on specific locations, faster
loading and unloading times, higher safety than some modes, and lower labor costs. The disadvantage primarily lies in higher fixed costs, potentially higher energy costs than some competing modes, and higher noise externalities. Whether the net benefits outweigh the net costs is an empirical question that awaits determination based on location specific factors, project costs, local demand, and network effects (depending on what else in the network exists). The optimal network design problem is hard (in the mathematical sense of hard, meaning optimal solutions are hard to find because of the combinatorics of the possible different network configurations), so heuristics and human judgment are used to design networks.


How to House the Homeless

How to House the Homeless
Russell Sage Foundation Press

Ellen, I.G. & O'Flaherty, B. (eds.).

How to House the Homeless, editors Ingrid Gould Ellen and Brendan O’Flaherty propose that the answers entail rethinking how housing markets operate and developing more efficient interventions in existing service programs. The book critically reassesses where we are now, analyzes the most promising policies and programs going forward, and offers a new agenda for future research. How to House the Homeless makes clear the inextricable link between homelessness and housing policy. Contributor Jill Khadduri reviews the current residential services system and housing subsidy programs. For the chronically homeless, she argues, a combination of assisted housing approaches can reach the greatest number of people and, specifically, an expanded Housing Choice Voucher system structured by location, income, and housing type can more efficiently reach people at-risk of becoming homeless and reduce time spent homeless. Robert Rosenheck examines the options available to homeless people with mental health problems and reviews the cost-effectiveness of five service models: system integration, supported housing, clinical case management, benefits outreach, and supported employment. He finds that only programs that subsidize housing make a noticeable dent in homelessness, and that no one program shows significant benefits in multiple domains of life. Contributor Sam Tsemberis assesses the development and cost-effectiveness of the Housing First program, which serves mentally ill homeless people in more than four hundred cities. He asserts that the program’s high housing retention rate and general effectiveness make it a viable candidate for replication across the country. Steven Raphael makes the case for a strong link between homelessness and local housing market regulations—which affect housing affordability—and shows that the problem is more prevalent in markets with stricter zoning laws. Finally, Brendan O’Flaherty bridges the theoretical gap between the worlds of public health and housing research, evaluating the pros and cons of subsidized housing programs and the economics at work in the rental housing market and home ownership. Ultimately, he suggests, the most viable strategies will serve as safety nets—“social insurance”—to reach people who are homeless now and to prevent homelessness in the future. It is crucial that the links between effective policy and the whole cycle of homelessness—life conditions, service systems, and housing markets—be made clear now. With a keen eye on the big picture of housing policy, How to House the Homeless shows what works and what doesn’t in reducing the numbers of homeless and reaching those most at risk.

Understanding the Challenges of Regional Ferry Service in New York City

Understanding the Challenges of Regional Ferry Service in New York City
RCWP 10-006 June, 2010

McCandless, Patrick

On February 12th, 2008, Christine Quinn, Speaker of the New York City Council, took to the dais at the City Council Chambers to deliver the State of the City Address.  Towards the 17th page of an 18 page address, the Speaker’s remarks turned to public transit and the Mayor’s recently released PlaNYC initiatives.  While transit is generally a hot topic in New York, Mayor Bloomberg had made transportation a centerpiece of his second term and was spending the winter in a campaign to convince the State Legislature to approve a congestion pricing scheme in Manhattan to finance transportation capital projects. 

“It’s only natural to look at our natural highways, our water ways... to move New Yorkers efficiently and sustainably.” Said Speaker Quinn,  “That’s why we are proposing and the Mayor has agreed to begin developing a comprehensive five borough, year-round New York City Ferry System.”   The Speaker explained that the idea for ferry service originated through a series of public hearings she held with her colleagues in the Council:

 “Soon after, we began exploring the concept of a pilot ferry service for the Rockaways…got a commitment from the Mayor to fund it…and that service should be up and running by this summer.

Two years and twelve days later, the rhetoric of the State of the City speech came crashing to an anti-climactic end, as a report in the Daily News announced the cancellation of the Rockaways service.  The ferry would cease operations at the end of March.  

Plans for a five borough Ferry System have not materialized, except for an East River ferry serving developments along the Queens/Brooklyn waterfront, currently with two sailings during the AM and PM peak hours is expected to offer more frequent service next year  The Rockaway route had not met ridership projections and was recovering only 15-30% of its operational costs from revenues collected at the farebox.   The failure of the Rockaway ferry service, combined with the cancellation of another newly opened ferry service between Yonkers and Lower Manhattan in 2009 has dashed the hopes of some who wished to exploit New York’s water resources to improve commuting options via ferries.  This has led to questions about the feasibility of expanding ferry service in New York City more broadly. 

As large sections of the New York City waterfront are reclaimed from decades of industrial land use, idyllic waterfront parks have been developed next to gleaming residential towers.  It seems only natural that ferries will soon serve a role in transporting residents and visitors to these new neighborhoods throughout the City.  However, recent experiences illustrate the many obstacles facing expanded ferry services in New York City
