Where a road for ground vehicles only meets a taxiway or at an end of usable service area for a ramp or taxiway, the light at the edge of the road or the final taxiway edge light may emit red light. Taxiway edge lights are spaced at a minimum of 50 to a maximum of 200 feet apart. On straightaways, the spacing is typically 200 feet.
Taxiway centerline lead-on lights – installed the same way as taxiway centerline lead-off Lights, but directing airplane traffic in the opposite direction. Land and hold short lights – a row of white pulsating lights installed across the runway to indicate hold short position on some runways that are facilitating land and hold short ...

Mixed adhesion and rope-hauled operation. The maximum gradient on adhesion is 8% between Vetta Scorcola and Cologna stops. Maximum gradient on the rope-hauled section is 26% between Romagna and S. Anastasio stops. [8] 1 in 12.5 (8.0%) Appenzell–St. Gallen–Trogen railway, Appenzeller Bahnen, Switzerland: 1 in 12.6 (7.9%)
Aircraft bridges must be designed to support the heaviest aircraft that may cross them, or that will cross them in the future. In 1963, a taxiway bridge at O'Hare International Airport, one of the busiest airports in the world, was planned to handle future aircraft weighing 365,000 pounds (166,000 kg), but aircraft weights doubled within two years of its construction.

The selection of lane width affects the safety, maximum capacity, and cost, of a highway. Safety is best at a width of 3.0 to 3.1 metres (9.8 to 10.2 ft) in urban settings, where both narrow (less than 2.8 metres (9 ft 2 in)) and wide (over 3.1 metres (10 ft)) lanes have higher crash risks.
For a line with a maximum speed of 60 km/h (37 mph), buffer-and-chain couplers increase the minimum radius to around 150 m (164 yd; 492 ft). As narrow-gauge railways , tramways , and rapid transit systems normally do not interchange with mainline railways, instances of these types of railway in Europe often use bufferless central couplers and ...
In the 1953 edition of Railway Engineering William H. Hay says "The ruling grade may be defined as the maximum gradient over which a tonnage train can be hauled with one locomotive....The ruling grade does not necessarily have the maximum gradient on the division. Momentum grades, pusher grades, or those that must regularly be doubled by ...
