Longer bridges can reduce the width of both shoulders to 4 feet (1.2 m). Existing bridges can remain part of the Interstate system if they have at least 12-foot-wide (3.7 m) lanes with 3.5-foot (1.1 m) shoulder on the left and a 10-foot (3.0 m) shoulder on the right, except that longer bridges can have 3.5 feet (1.1 m) shoulders on both sides.
[22] [23] [24] Florida's ESU plan prohibits trucks, busses, and trailers from driving on the shoulder and limits the speed limit to 50 mph on the shoulder, which is typically only 10 feet (3.0 m) wide compared to the standard 12 feet (3.7 m) width of highway travel lanes and contains rumble strips.

Carrying capacity is also optimal at a width of 3.0 to 3.1 metres (9.8 to 10.2 ft), both for motor traffic and for bicycles. [8] Throughput is maximal at 18 miles per hour (29 km/h); as lane width decreases to 3.0 to 3.1 metres (9.8 to 10.2 ft), traffic speed diminishes, and so does the interval between vehicles. [8] [9]
The Transportation Association of Canada and US FHWA guidelines basically specify that a width of 1.5 m (4.9 ft) of clear paved shoulder between the outside of the rumble strip and the edge of pavement is adequate to provide cyclists with a clear travel path. [12] [33]
The primary high-speed motorways in Croatia are called autoceste (singular: autocesta; Croatian pronunciation: [ˈaʊtotsesta]), and they are defined as roads with at least two lanes in each direction (including hard shoulder) and a speed limit of not less than 80 km/h (50 mph). The typical speed limit is 130 km/h (81 mph).
Size questions remain as he measured in at 5-foot-11 and 194 pounds but speed is not. His 4.39-second 40-yard dash could work him into consideration as one of the first three cornerbacks off the ...
Lane capacity varies widely due to conditions such as neighboring lanes, lane width, elements next to the road, number of driveways, presence of parking, speed limits, number of heavy vehicles and so on – the range can be as low as 1000 passenger cars / hour to as high as 4800 passenger cars / hour but mostly falls between 1500 and 2400 ...
Regulatory signs give instructions to motorists, pedestrians, and cyclists. Signs including Stop, Yield, No Turns, No Trucks, No Parking, No Stopping, Minimum Speed, Right Turn Only, Do Not Enter, Weight Limit, and Speed Limit are considered regulatory signs. Some have special shapes, such as the octagon for the Stop sign.
