Slope may still be expressed when the horizontal run is not known: the rise can be divided by the hypotenuse (the slope length). This is not the usual way to specify slope; this nonstandard expression follows the sine function rather than the tangent function, so it calls a 45 degree slope a 71 percent grade instead of a 100 percent. But in ...
A new powered bike escalator in Paris, 2020. Bicycle lifts are powered mechanical systems for moving bicycles uphill. They are used where the steepness of a slope or other situations like subway crowds make riding uphill difficult. They are used on transit to make areas more accessible and reduce conflict.

A steeply banked turn on a ramp connecting eastbound California State Route 92 to northbound Interstate 880 in Hayward, California. Cyclists take a tight downhill corner in the Beanpot Criterium at Tufts University. When considering the effects of friction on the system, once again we need to note which way the friction force is pointing.

Grade-separated road junctions are typically space-intensive, complicated, and costly, due to the need for large physical structures such as tunnels, ramps, and bridges. Their height can be obtrusive, and this, combined with the large traffic volumes that grade-separated roads attract, tend to make them unpopular to nearby landowners and residents.
