Transportation into, out of, and within cities has been one of the key enablers of urban growth. As cities grow larger and more complex, ensuring that people, goods, and information flow smoothly will become all the more important.

As humanity becomes more urbanized, maintaining health and happiness in crowded environments becomes critical. Clean air, clean water, and efficient transit systems are essential parts of the solution.

Structures are cities' building blocks, and as cities grow and change, the role of structures must change as well. In some cases, it means protecting and modifying existing buildings; in others, it means designing new structures to meet emerging needs.

The very structures of cities play an important role in urban environments, from influencing residents' energy needs to affecting local climates and ensuring resilience against natural hazards. Developing new structures and maintaining existing ones are important challenges.

The Siebel Scholars Foundation has awarded Siebel Scholars fellowships to five Princeton University graduate students in computer science.

Princeton University's newly established Metropolis Project is creating a research ecosystem that enables Princeton to play a central role in meeting the urbanization challenge.

Engineering faculty members welcomed the Class of 2023 to the School of Engineering and Applied Science on Monday afternoon, with Vice Dean Antoine Kahn telling students that as engineers, they will "have the ability to use your technical expertise during your lifetime to improve and sustain quality of life in the world for everybody."

In summer heat, cities may swelter more than nearby suburbs and rural areas. And while the size of this urban heat island effect varies widely among the world's cities, heat island intensity can largely be explained by a city's population and precipitation level, researchers reported in a paper published Sept. 4 in the journal Nature. The analysis suggests that cooling cities by planting more vegetation may be more effective in drier regions than in wetter ones.

Princeton researchers have developed new maps that predict coastal flooding for every county on the Eastern and Gulf Coasts and find 100-year floods could become annual occurrences in New Ehttps://environment.princeton.edu/ngland; and happen every one to 30 years along the southeast Atlantic and Gulf of Mexico shorelines.
