Drive time is the daypart in which radio broadcasters can reach the most people who listen to car radios while driving, usually to and from work, or on public transportation. [1] Drive-time periods are when the number of radio listeners in this class is at its peak and, thus, commercial radio can generate the most revenue from advertising . [ 2 ]
An isochrone (iso = equal, chrone = time) is defined as "a line drawn on a map connecting points at which something occurs or arrives at the same time". [2] In hydrology and transportation planning isochrone maps are commonly used to depict areas of equal travel time. The term is also used in cardiology [3] [4] [5] as a tool to visually detect ...
The turning radius (alternatively, turning diameter or turning circle) of a vehicle defines the minimum dimension (typically the radius or diameter, respectively) of available space required for that vehicle to make a semi-circular U-turn without skidding. The Oxford English Dictionary describes turning circle as "the smallest circle within ...
Minimum railway curve radius. 90-foot (27.43 m) radii on the elevated 4 ft 81⁄2 in ( 1,435 mm) standard gauge Chicago 'L'. There is no room for longer radii above this street intersection at this cross junction at the Wells and Lake street intersection in the northwest corner of the loop. The minimum railway curve radius is the shortest ...
Left-hand traffic ( LHT) and right-hand traffic ( RHT) are the practices, in bidirectional traffic, of keeping to the left side and to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes called the rule of the road. [1] The terms right- and left-hand drive refer to the position of the driver and the ...
Austin, Travis County and Williamson County have been the site of human habitation since at least 9200 BC. The area's earliest known inhabitants lived during the late Pleistocene (Ice Age) and are linked to the Clovis culture around 9200 BC (over 11,200 years ago), based on evidence found throughout the area and documented at the much-studied Gault Site, midway between Georgetown and Fort Cavazos.
