The center of activities of Santiago de Chile has been continuously evolving towards the eastern part of the city, where the most affluent residents live. This paper characterizes the direction and magnitude of this evolution through an indicator stating how much the built surface area for service purposes grows in different areas in the city. To identify the impact of this evolution, we compare residents’ travel-time distributions from different sectors in the city to the central area. This travel-time comparison is focused on the sectors where informal settlements were massively eradicated between 1978–1985 and those areas where the settlements were relocated. This analysis show that this policy and the consequent evolution of the city were detrimental to the affected families, significantly increasing average travel time to the extended center of the city and inequality among different socioeconomic groups in the city. Although the phenomenon is quite visible to everyone, it has not received any policy reaction from the authority. These findings suggest that middle and low-income sectors would benefit if policies driving the evolution of the center of activities towards them were implemented.

Looking at evolving urban governance and planning practices in the city of Lahore, Pakistan, the article aims to understand—from an Evolutionary Governance Theory perspective—to what extent these practices steer paths and modes of service provision and housing for low-income residents. With a focus on the endurance and transformations of urban governance practices and institutions, we first explore the influence of the changing development discourse and the impact it has had on the (re)configuration of urban governance and housing policies in Lahore. Second, drawing on extensive fieldwork and empirical data collected between 2012 and 2016, we highlight three vignettes depicting the development of different housing options for low-income residents in Lahore, i.e., a government-steered subsidised housing scheme, a privately developed ‘pro-poor’ settlement in the peri-urban fringe of the city, and residential colonies already—or in the process of being—regularised. By analysing the relationship between governance frameworks, the establishment of the three types of settlements and how residents manage to access housing and services there, we demonstrate how purposive deregulation in governance and policy generates a disconnect between urban normative frameworks (i.e., urban planning tools and pro-poor housing policies) and residents’ needs and everyday practices. We argue that this highly political process is not exclusively path-dependent but has also allowed the creation of liminal spaces based on agency and collective action strategies of low-income residents.

As a result of rapid urbanization and motorization in China, numerous mega-cities have emerged, and large numbers of people live and work in the city centers. Consequently, developing a public transport-oriented urban structure and promoting sustainable development are major planning strategies for the country. To understand the impact of rail transit on motorization in a high-density city center, we conduct a household travel survey in three neighborhoods around metro stations in the central area of Shanghai. We examine the car buying and commuting behavior of those Shanghai “original” residents who lived there when the city began growing, engulfing them in the center. Studies have shown that 40 percent of commuters in the city center commute outward, following a virtually reversed commute pattern, and the factors significantly affecting their car purchasing choice include their attitude toward cars and transit, household incomes, ownership of the apartments they live in, and the distance between family members’ workplaces and nearest metro stations. Despite easy access to the metro from their home in the city center, those who purchase their apartment units also likely own a car, while those who rent their apartment units are less likely to own a car; however, these odds are still higher than for those who live in an apartment unit inherited from their relatives or provided by their company. In the city center, if a family owns a car, then that car would almost certainly be used for daily commuting. A multinomial logistic model is applied to examine the factors influencing the tendency for using cars. The results show that people’s choices of commuting by alternative modes rather than cars are also shaped by their attitude toward public transportation, but other factors can also subtly change people’s commuting behavior under certain conditions. The commuting distance discourages people from walking and taking buses (but not metro). As the egress distance to the workplace increases, the metro becomes less appealing than cars. Mixed land use encourages people to walk or take buses instead of driving. Older people prefer riding buses and walking to driving, and female respondents tend to prefer walking, cycling, and riding the metro to driving compared to male respondents. These findings contribute to understanding the behavior of people who are familiar with public transportation and how to encourage them to switch from driving cars to alternative transport modes.

Abstract In this paper, the authors propose a framework which enables them to analyse the economic impact of new highway links between Montreal and eleven surrounding cities, specifically the impact on the economic structure of those cities. The authors observe a relationship between changes in accessibility (to Montreal) and economic structure. Greater accessibility resulting from new highway construction seems generally to favour industrial growth and diversification, although a very rapid and radical change in accessibility can also have negative consequences on the short run. The service sector appears particularly sensitive to changes in accessibility. The authors observe a cut off point of one hour's travel time: as soon as city falls within this travel-time zone its service sector (especially more the sophisticated services) systematically declines. Finally, the authors conclude that the precise nature of the impact of increased accessibility to Montreal is largely a function of the original economic structure of the city concerned: certain structures are more sensitive to changes in accessibility than others.

Reducing passenger flow through highly frequented bottlenecks in public transportation networks is a well-known urban planning problem. This issue has become even more relevant since the outbreak of the SARS-CoV-2 pandemic and the necessity for minimum distances between passengers. We propose an approach that allows to dynamically navigate passengers around dangerously crowded stations to better distribute the passenger load across an entire urban public transport network. This is achieved through the introduction of new constraints into routing requests, that enable the avoidance of specific nodes in a network. These requests consider walks, bikes, metros, subways, trams and buses as possible modes of transportation. An implementation of the approach is provided in cooperation with the Munich Travel Corporation (MVG) for the city of Munich, to simulate the effects on a real city’s urban traffic flow. Among other factors, the impact on the travel time was simulated given that the two major exchange points in the network were to be avoided. With an increase from 26.5 to 26.8 minutes on the average travel time, the simulation suggests that the time penalty might be worth the safety benefits.

The Impact

Bus bunching can lead to unreliable bus services if not controlled properly. Passengers will suffer from the uncertainty of travel time and the excessive waiting time. Existing dynamic holding strategies to address bus bunching have two major limitations. First, existing models often rely on large slack time to ensure the validity of the underlying model. Such large slack time can significantly reduce the bus operation efficiency by increasing the overall route travel times. Second, the existing holding strategies rarely consider the impact on the schedule planning. Undesirable results such as bus overloading issues arise when the bus fleet size is limited. This paper explores analytically the relationship between the slack time and the effect of holding control. The optimal slack time determined based on the derived relationship is found to be ten times smaller than in previous models based on numerical simulation results. An optimization model is developed with passenger-orient objective function in terms of travel cost and constraints such as fleet size limit, layover time at terminals, and other schedule planning factors. The optimal choice of control stops, control parameters, and slack time can be achieved by solving the optimization. The proposed model is validated with a case study established based on field data collected from Chengdu, China. The numerical simulation uses the field passenger demand, bus average travel time, travel time variance of road segments, and signal timings. Results show that the proposed model significantly reduce passengers average travel time compared with existing methods.

The City of Clemson, along with the National Wildlife Federation, Habitat for Humanity, and Clemson Univ., recently formed a strategic alliance to incorporate ideas for the landscaping of low-income homes. Their goal was to create an aesthetically pleasing, environmentally responsible design that catered to the future development of the families involved. The low-income housing project was selected as an independent study for Spring 1998. As student project manager I coordinated and documented the project. Objectives of the project were: 1) to promote knowledge and research on environmental issues and culturally diverse populations; 2) to create backyard wildlife habitats and sustainable community environments for low income families; 3) to provide students with the opportunity to learn and mature by participating in a long-term project involving a measurable impact. Project steps included analysis, research, design, planning, scheduling, implementation, and reflection on the impact made by those involved. The City of Clemson, along with the others involved, was delighted to be the first to address the issue of enhancing open space around low-income buildings in addition to landscaping the properties surrounding the homes.

Inadequately planned transport systems result to traffic congestion, a challenge that has for long been a thorn in Dar es Salaam, the city most affected in Tanzania. Although traffic congestion has been a major concern in Dar es Salaam, marked reluctance has been noticed in taking measures towards a lasting solution thus, it is of diminutive surprise that limited studies and documentations on the same are in existence. Therefore, this study assesses traffic congestion in Dar es Salaam and particularly its implications for workers’ productivity. Travel time and productivity indexes were established from a sample of 96 workers who used public transport along Morogoro and Mandela Roads. Travel time index (TTI) is the ratio of the average travel time during peak period to the travel time during off-peak period. Findings reveal that TTI was 2.19. Workers spent about 2 times of the average commuting time to work and 3 times of the same commuting from work to their various residences. About 2.5 hours were lost on traffic jam per day and that people worked 1.4 times less than the required time due to traffic congestion. It was further established that in 10 working days, almost 3 days were lost to traffic congestion. Since there are ongoing efforts to improve the transport system through the Bus Rapid Transit (BRT) project, it remains to be seen as to what extent traffic congestion will be reduced. In either case, this study provides a benchmark for comparisons.

This article explores attitudes and barriers to work, and the impact of punitive welfare reform in the City of Salford (Greater Manchester). Contextualising our discussion in relation to the contemporary landscape of inequality and social class in the UK, we draw attention to the trends towards the expansion of low-paid work, precarity, and stigmatisation, and highlight the need for more qualitative, geographically sensitive studies of how these phenomena are being played out. Describing the economic context of the City of Salford and the current state of its labour market, we then present the findings from qualitative interviews with a sample of low income, mostly working-class participants, who describe their orientations towards employment, perceptions of the labour market, barriers to employment and interactions with punitive welfare reform. Ultimately, we conclude by noting that both strategies of neoliberal statecraft aimed at the reduction of the charitable state described by Wacquant are at play in Salford and that their result is a discouragement from claiming welfare and a recommodification of labour.
