Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, [Note 1] and negligibly by the tires' rolling resistance and vehicle's air drag.
The California Trail was an emigrant trail of about 1,600 mi (2,600 km) across the western half of the North American continent from Missouri River towns to what is now the state of California. After it was established, the first half of the California Trail followed the same corridor of networked river valley trails as the Oregon Trail and the ...
Pacific Crest Trail. The Pacific Crest Trail ( PCT ), officially designated as the Pacific Crest National Scenic Trail, is a long-distance hiking and equestrian trail closely aligned with the highest portion of the Cascade and Sierra Nevada mountain ranges, which lie 100 to 150 miles (160 to 240 km) east of the U.S. Pacific coast.
The Coast Starlight is a long-distance passenger train operated by Amtrak on the West Coast of the United States between Seattle and Los Angeles via Portland and the San Francisco Bay Area. The train, which has operated continuously since Amtrak's formation in 1971, was the first to offer direct service between Seattle and Los Angeles.
The two-second rule is useful as it can be applied to any speed. Drivers can find it difficult to estimate the correct distance from the car in front, let alone remember the stopping distances that are required for a given speed, or to compute the equation on the fly (for example, braking distance is roughly calculated as b = s 2 /20, where b is the braking distance in metres and s is car ...
California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km 2 ), California is among the most geographically diverse states. The Sierra Nevada, the fertile farmlands of the Central Valley, and the arid Mojave Desert of the south are some of the geographic features of this U.S. state.
California’s largest wildfire of the year has burned an area larger than the size of the entire city of Los Angeles, destroyed dozens of buildings and forced thousands of residents to flee their ...
Route assignment, route choice, or traffic assignment concerns the selection of routes (alternatively called paths) between origins and destinations in transportation networks. It is the fourth step in the conventional transportation forecasting model, following trip generation, trip distribution, and mode choice.
