The preferred walking speed is the speed at which humans or animals choose to walk. Many people tend to walk at about 1.42 metres per second (5.1 km/h; 3.2 mph; 4.7 ft/s). [1] [2] [3] Individuals find slower or faster speeds uncomfortable. Horses have also demonstrated normal, narrow distributions of preferred walking speed within a given gait ...
In the United States, speed limits are set by each state or territory. States have also allowed counties and municipalities to enact typically lower limits. Highway speed limits can range from an urban low of 25 mph (40 km/h) to a rural high of 85 mph (137 km/h). Speed limits are typically posted in increments of five miles per hour (8 km/h).
The rural default speed limit is 45 mph but may be increased to 50 mph (80 km/h). In residential areas, only multilane roads have limits up to 35 mph (56 km/h), other roads are restricted to a maximum speed of 25 mph (40 km/h). Only urban and rural school zones have limits up to 15 to 25 mph (24–40 km/h).
Urban area. An urban area, built-up area or urban agglomeration is a human settlement with a high population density and an infrastructure of built environment. This is the core of a metropolitan statistical area in the United States, if it contains a population of more than 50,000.
The wind profile power law relationship is. where is the wind speed (in metres per second) at height (in metres), and is the known wind speed at a reference height . The exponent ( ) is an empirically derived coefficient that varies dependent upon the stability of the atmosphere. For neutral stability conditions, is approximately 1/7, or 0.143.
An urban canyon (also known as a street canyon or skyscraper canyon) is a place where the street is flanked by buildings on both sides creating a canyon -like environment, evolved etymologically from the Canyon of Heroes in Manhattan. Such human-built canyons are made when streets separate dense blocks of structures, especially skyscrapers.

The Urban Driving Cycle ECE-15 (or just UDC) was introduced first in 1970 as part of ECE vehicle regulations; the recent version is defined by ECE R83, R84 and R101. [2] [3] [6] The cycle has been designed to represent typical driving conditions of busy European cities, and is characterized by low engine load, low exhaust gas temperature, and a ...
