Speed limits on road traffic, as used in most countries, set the legal maximum speed at which vehicles may travel on a given stretch of road. Speed limits are generally indicated on a traffic sign reflecting the maximum permitted speed, expressed as kilometres per hour (km/h) or miles per hour (mph) or both. Speed limits are commonly set by the legislative bodies of national or provincial governments and enforced by national or regional police and judicial authorities. Speed limits may also be variable, or in some places nonexistent, such as on most of the Autobahnen in Germany.
A dual carriageway (BrE) or a divided highway (AmE) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation (BrE) or median (AmE). Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways.
In the United States and Canada, low-speed vehicle (LSV) regulations allow relaxed design and registration laws for four-wheel vehicles that have a maximum capable speed of about 25 mph (40 km/h). Several other countries have similar regulations.
A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, and partial controlled-access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway, including limited or no access to adjacent property, some degree of separation of opposing traffic flow, use of grade separated interchanges to some extent, prohibition of slow modes of transport, such as bicycles, horse-drawn vehicles or ridden horses, or self-propelled agricultural machines; and very few or no intersecting cross-streets or level crossings. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.
The expressways of Japan make up a large network of controlled-access toll expressways.
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway, and expressway. Other similar terms include throughway or thruway and parkway. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic.
The Metropolitan Manila Development Authority is a government agency of the Philippines responsible for constituting the regional government of Metro Manila, comprising the capital city of Manila, the cities of Quezon City, Caloocan, Pasay, Mandaluyong, Makati, Pasig, Marikina, Muntinlupa, Las Piñas, Parañaque, Valenzuela, Malabon, Taguig, Navotas and San Juan, and the municipality of Pateros.
In the United States, speed limits are set by each state or territory. States have also allowed counties and municipalities to enact typically lower limits. Highway speed limits can range from an urban low of 25 mph (40 km/h) to a rural high of 85 mph (137 km/h). Speed limits are typically posted in increments of five miles per hour (8 km/h). Some states have lower limits for trucks, some also have night and/or minimum speed limits.
The National Maximum Speed Limit (NMSL) was a provision of the federal government of the United States 1974 Emergency Highway Energy Conservation Act that effectively prohibited speed limits higher than 55 miles per hour (89 km/h). The limit was increased to 65 miles per hour (105 km/h) in 1987. It was drafted in response to oil price spikes and supply disruptions during the 1973 oil crisis. Even after fuel costs began to decrease over time the law would remain in place until 1995 as proponents claimed it reduced traffic fatalities.
Commonwealth Avenue, formerly known as Don Mariano Marcos Avenue, is a 12.4-kilometer (7.7 mi) highway located in Quezon City, Philippines. It spans six to eighteen lanes, making it the widest road in the country. The avenue is one of the major roads in Metro Manila and is designated as part of Radial Road 7 (R-7) of the older Manila arterial road system and National Route 170 (N170) of the Philippine highway network.
A speed limit is the limit of speed allowed by law for road vehicles, usually the maximum speed allowed. Occasionally, there is a minimum speed limit. Advisory speed limits also exist, which are recommended but not mandatory speeds. Speed limits are commonly set by the legislative bodies of national or local governments.
The transportation system in Metro Manila covers the road network, rail network, ferries, ports and airports located within the metropolitan Manila area. Road transportation in Metro Manila is diverse, composed of many types of private and public transport vehicles. These include taxis, buses, jeepneys, tricycles and pedicabs. In some areas, especially in Divisoria and large public markets, two-stroke motors are fitted in the pedicabs and are used for goods transport. Regardless of modernity, horse-drawn kalesas are still used in the streets of Binondo and Intramuros. Ridesharing services such as Grab also operate within Metro Manila.
Road speed limits in the United Kingdom are used to define the maximum legal speed for vehicles using public roads in the UK.
The highest speed limit in Japan is 120 km/h, which applies on sections of Shin-Tōmei Expressway (E1A) and Tōhoku Expressway (E4), and expressways in the Kantō Plain leading to Tokyo, although a speed limit of 120 km/h is planned to be introduced on some more expressways.
General speed limits in New Zealand are set by the New Zealand government. The speed limit in each location is indicated on a nearby traffic sign or by the presence of street lighting. The limits have been posted in kilometres per hour (km/h) since 1974. Before then, when New Zealand used imperial units, maximum speeds were displayed in miles per hour (mph). Today, limits range from 10 km/h (6.2 mph) to 110 km/h (68 mph); in urban areas the default speed limit is 50 km/h (31 mph).
Speed limits in the United States vary depending on jurisdiction. Rural freeway speed limits of 70 to 80 mph are common in the Western United States, while such highways are typically posted at 65 or 70 mph in the Eastern United States. States may also set separate speed limits for trucks and night travel along with minimum speed limits. The highest speed limit in the country is 85 mph (137 km/h), which is posted on a single stretch of tollway in exurban areas outside Austin, Texas. The lowest maximum speed limit in the country is 30 miles per hour (48 km/h) in American Samoa.
The Philippine expressway network, also known as the High Standard Highway Network, is a controlled-access highway network managed by the Department of Public Works and Highways (DPWH) which consists of all expressways and regional high standard highways in the Philippines.
According to a "Global Driver Satisfaction" survey conducted by the navigation app Waze in 2015, Metro Manila had the "worst traffic on Southeast Asia". Emerson Carlos, MMDA assistant general manager for operation has mentioned that in 2015, motor vehicle registrations in Metro Manila peaked at around 2.5 million.
Cycling is a popular mode of transport and recreational sport in the Philippines. Bicycles were first introduced to the archipelago in the 1880s during the Spanish colonial occupation of the Philippines and served as a common mode of transport, especially among the local mestizo population.
Traffic law in the Philippines consists of multiple laws that govern the regulation and management of road transportation and the conduct of road users within the country.
