Green infrastructure harnesses nature to the benefit of the built environments as well as human and animal life.

When a government creates incentives or disincentives to influence how and when you travel—that's transportation demand management.

Combining elements of rapid transit with buses, BRT systems can provide faster, more reliable service at lower cost than rail-based transit.

A road diet ‘trims down’ multilane roadways by reallocating street space to uses other than car traffic, improving safety for pedestrians, encouraging multimodal travel, and enhancing overall livability.

The buzzword recently popularized by urbanists describes an urban form that dominated cities prior to the rise of autocentric planning.

If you’ve ever noticed a public bench split in half by a metal bar, or a series of seemingly ornamental boulders blocking the sidewalk under a high-rise overhang, you’ve seen what is often described as defensive urbanism or ‘hostile architecture.’

Safe and comprehensive bike facilities play a crucial role in keeping vulnerable road users safe, promoting biking as an everyday transit mode, and reducing carbon emissions and traffic congestion by encouraging a shift to more multimodal transportation.

The primary environmental law to regulate water pollution in the United States, the Clean Water Act, went into effect 50 years ago, on October 18, 1972.

The woonerf, a type of road design that encourages multimodal transportation and blends pedestrian and vehicle space, was born as a reaction to the car-centric development that began dominating American and European city planning in the mid-twentieth century.

Variances allow for development projects to deviate from the zoning code on a case-by-case basis—if the project developer can prove a unique economic or physical hardship.

Zoning amendments change the existing zoning code by either of two methods: changing the text of the zoning code or changing the zoning map.

Traffic calming is a set of design interventions aimed at slowing or diverting car traffic to reduce the chance of crashes and improve safety for all road users.

Man-made surfaces and urban density contribute to higher temperatures, intensifying heat waves and posing a growing danger to public health.

In urbanism and planning, the term transect provides a conceptual framework for understanding how the scale of built environments can vary from place to place.

GIS software, which combines location information with data about a range of other attributes, has become an indispensable tool for mapping and spatial analysis in urban planning and dozens of other fields.

YIMBY, an acronym standing for "Yes In My Backyard," describes advocates who support housing development as a response to the outcomes of restrictive zoning and planning policies.

Tactical urbanism, one of the most common buzzwords in planning over the past decade, describes a variety of low-cost, incremental public realm design interventions.

A zoning overlay district superimposes an additional set of regulations over an existing zoning district, or multiple zoning districts.

“If you build it, they will come.”

The concept of incrementalism can be applied to numerous fields and disciplines—one of which is planning. In the field of planning, the word incremental is usually used as an adjective to describe other planning words, such as code reform and development.
