Curitiba has a planned transportation system, which includes lanes on major streets devoted to a bus rapid transit system.
The buses are split into three sections (bi-articulated) and stop at designated elevated tubes, complete with access for disabled riders.
Buses charge one price regardless of distance.

The city preserves and cares for its green areas, boasting 51.5 square metres (554 sq ft) of green space per inhabitant.

In the 1940s and 1950s, Alfred Agache, cofounder of the French Society for Urban Studies, was hired to produce the first city plan.
It emphasised a star of boulevards, with public amenities downtown, an industrial district and sanitation.
The plan was too expensive to complete.

By the 1960s, Curitiba's population had reached 430,000.
Some residents feared that the growth in population threatened to damage the character of the city.
In 1964, Mayor Ivo Arzua solicited proposals for urban design.
Architect Jaime Lerner, who later became mayor, led a team from the Universidade Federal do Paraná that suggested strict controls on urban sprawl, reduced traffic in the downtown area, preservation of Curitiba's Historic Sector and a convenient and affordable public transit system.

This plan, known as the Curitiba Master Plan, was adopted in 1968.
Lerner closed XV de Novembro St. to vehicles, because it had high pedestrian traffic.
The plan had a new road design to minimise traffic: the Trinary Road System.
This used two one-way streets moving in opposite directions that surround a smaller, two-lane street where the express buses have an exclusive lane.
Five of these roads form a star that converges on the city centre.
Land farther from these roads is zoned for lower density development, to pull traffic away from the main roads.
In a number of areas subject to floods, buildings were condemned and the land became parks.

Today, Curitiba is considered one of the world's best examples of urban planning.
In June 1996, the chairman of the Habitat II summit of mayors and urban planners in Istanbul praised Curitiba as "the most innovative city in the country."

Curitiba was recently recommended by UNESCO as a model for the reconstruction of the cities of Afghanistan.
In the 1980s, the RIT (Rede Integrada de Transporte, Integrated Transport Network) was created.
At the same time, the city began building the "Faróis de Saber" (Lighthouses of Knowledge) educational centres.
The city has more than 400 square kilometres (154 sq mi) of public parks and forests.

In 2007, the city placed third in a list of "15 Green Cities" in the world, according to Grist magazine, after Reykjavík in Iceland and Portland, Oregon in the United States.
As a result, according to one survey, 99% of Curitibans are happy with their hometown.

Jaime Lerner suggests urban acupuncture as the future solution for contemporary urban issues; focusing on very narrow pressure points in cities, can create positive ripple effects.
Urban "acupuncture" reclaims land for the public and emphasizes the importance of community development through small interventions in design of cities.
It emphasises pinpoint interventions that can be accomplished quickly to create a make an immediate impact.

The "capacity building job line" was created to accelerate economic development.
Key initiatives include the South-Circular bus line, which links the southern and eastern regions of town; Entrepreneurial "Sheds", business incubators designed to help small companies get established and prosper; and the Crafts Lycée, which trains people for professions such as marketing and finance.
Specifically, the goal is to provide jobs and income for the unemployed among 400,000 people living in 15 peripheral towns, and to structure and develop the region according to integrated planning principles.
About 15,000 new jobs were generated by 2013.

According to Jonas Rabinovitch, a United Nations senior adviser and former planner at the Curitiba Research and Urban Planning Institute (IPPUC), up to 8% of Curitiba's population still lived in favelas as of 2016.
According to 2010 census data collect
