Urban science seeks to understand the fundamental processes that drive, shape and sustain cities and urbanization. It is a multi/transdisciplinary approach involving concepts, methods and research from the social, natural, engineering and computational sciences, along with the humanities. This report is intended to convey the current “state of the art” in urban science while also clearly indicating how urban science builds upon and complements (but does not replace) prior work on cities and urbanization in many other disciplines. The report does not aim at a fully comprehensive synopsis of...

Spatial Sensitivity Analysis for Urban Land use Prediction with Physics-constrained Conditional Generative Adversarial Networks

Albert, Adrian
Kaur, Jasleen
Strano, Emanuele
Gonzalez, Marta
2019

Accurately forecasting urban development and its environmental and climate impacts critically depends on realistic models of the spatial structure of the built environment, and of its dependence on key factors such as population and economic development. Scenario simulation and sensitivity analysis, i.e., predicting how changes in underlying factors at a given location affect urbanization outcomes at other locations, is currently not achievable at a large scale with traditional urban growth models, which are either too simplistic, or depend on detailed locally-collected socioeconomic data...

Socio-economic, Built Environment, and Mobility Conditions Associated with Crime: A Study of Multiple Cities

Nowadays, 23% of the world population lives in multi-million cities. In these metropolises, criminal activity is much higher and violent than in either small cities or rural areas. Thus, understanding what factors influence urban crime in big cities is a pressing need. Seminal studies analyse crime records through historical panel data or analysis of historical patterns combined with ecological factor and exploratory mapping. More recently, machine learning methods have provided informed crime prediction over time. However, previous studies have focused on a single city at a time,...

Multiple Airport Regions Based on Inter-airport Temporal Distances

Sun, Xiaoqian

2017

We formulate and implement a new metric for identifying multiple airport regions (MARs) around the world, based on the temporal distance between airports. This metric, opposed to existing studies based on spatial distance, takes into account the real travel time between airports of latent passengers and their journeys via ground transportation. We investigate a variety of properties of the newly built MARs network at the global scale for the year 2015, including the importance of MARs in global air transportation, similarity clustering, destination overlap, and airport roles inside a MAR....

Market Segmentation of New Gateway Airports Incorporating Passengers’ Curiosity

To serve more markets for supporting its sustainable development, Zhuhai airport tends to act as a new gateway by providing an air–bridge–air path that links its domestic network to the international air routes of Hong Kong Airport, through surface transportation via the Hongkong–Zhuhai–Macao Bridge. In order to identify the target passengers using the new gateway service, this paper proposes a market segmentation approach which incorporates the heterogeneity among passengers in the choice of the air–bridge–air route and explicitly incorporates people’s curiosity about the new service. A...

Motorcyclists are the fastest growing road user group in Latin America, and account for 25% of all road traffic collision deaths. This study examines the relationship between motorcyclist mortality and the built and social urban environment in Latin American cities.

Development of Comprehensive Roadmap and Resource Guide Towards Congestion Reduction [Brief]

Traffic congestion has become an increasingly critical issue across the United States, disrupting transportation networks and impacting society in ways that extend beyond mobility. Congestion contributes to declining public health, reduced quality of life, and environmental concerns such as pollution, noise, and stress (Meyer, 1997). Nationally, travel delays rose from 5.1 billion hours in 2000 to 8.7 billion hours in 2019, while fuel waste increased from 2.4 billion gallons to 3.5 billion gallons over the same period. Similarly, excess greenhouse gas emissions escalated from 25 million...

New Methodologies for Airport Environmental Impact Analysis

Hansen, Mark

Marchi, Richard F.
2013

While airports have always had an uneasy relationship with the environment, the relationship has evolved dramatically in recent years. On the one hand, greenhouse gas (GHG) emissions have become a much stronger cause for concern. The global character of the GHG problem challenges established patterns of thinking about airport environmental impacts. At the same time, the canonical airport environmental problem, noise, has been transformed as the result of improving capabilities to redistribute it through procedures enabled by advanced navigation technologies. In this setting, concepts such...

Freeway Expansion and Land Development: An Empirical Analysis of Transportation Corridors

Hansen, Mark

2001

Road transport infrastructure can, together with other factors, influence location choices and decisions involving residential, commercial, and industrial development. The network of roads and highways provides a means for access for workers and materials as well as a way for distributing products and services. Greater access lowers the costs of transportation and therefore increases the supply of many resources, including land, labor, and materials. An investment in highway infrastructure can have a variety of land use impacts, depending upon which of the above factors have been affected...

Computer Programs for Traffic Operations

The objective of this project was to develop recommendations toward a statewide policy of congestion responsive freeway ramp metering operation. The research is performed in two phases. In phase 1, alternative ramp metering activation strategies were evaluated through simulation modeling on a real-world freeway test site. In phase 2, "before" and "after" field data will be collected and analyzed on freeway test sites that have implemented congestion responsive ramp metering activation. This report describes the research performed in phase 1 of the project. A section of the US-101 freeway...
