Managed Lanes
A managed lane is a type of highway lane that is operated with a management scheme, such as lane use restrictions or variable tolling, to optimize traffic flow, vehicle throughput, or both. Definitions and goals vary among transport agencies, but managed lanes are generally implemented to achieve an improved operational condition on a highway, such as improving traffic speed and throughput, reducing air pollution, and improving safety. Types of managed lanes include High-occupancy vehicle (HOV) lanes, High-occupancy toll lanes, express toll lanes, reversible lanes, and bus lanes. Most managed lane facilities are located in the United States, although HOV and bus lanes can be found in many other countries; outside of the US, many countries use active traffic management that manage all lanes of a highway. Definition The definition of a managed lane varies among transport agencies. The United States' Federal Highway Administration describes managed lanes as "highway facilities or a ...

404HOV Lane
4 (four) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is tetraphobia, considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically 3, three. The sum of the first four prime numbers 2, two + 3, three + 5, five + 7, seven is the only sum of four consecutive prime numbers that yields an Parity (mathematics), odd prime number, 17 (number), seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, 3, three and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Vehicle
A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. The basic principle with hybrid vehicles is that the different motors work better at different speeds; the electric motor is more efficient at producing torque, or turning power, and the combustion engine is better for maintaining high speed than a typical electric motor. Switching from one to the other at the proper time while speeding up yields a win-win in terms of energy efficiency, such that it translates into greater fuel efficiency. Vehicle types Two-wheeled and cycle-type vehicles Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and the rider's muscles. Early prototype motorcycles in the late 19th century used the same principle. * In a parall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truck Bypass Lanes For I-15 And I-405 Interchange
A truck or lorry is a motor vehicle designed to transport cargo, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "tractor". The majority of trucks currently in use are still powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in the US, Canada, and Mexico.

New Jersey Turnpike
The New Jersey Turnpike (NJTP) is a system of controlled-access highways in the U.S. state of New Jersey. The turnpike is maintained by the New Jersey Turnpike Authority (NJTA).The Garden State Parkway, although maintained by NJTA, is not considered part of the turnpike. The mainline's southern terminus is at a complex interchange with Interstate 295 (Delaware–Pennsylvania), Interstate 295 (I-295), U.S. Route 40 in New Jersey, U.S. Route 40 (US 40), U.S. Route 130, US 130, and New Jersey Route 49, Route 49 near the border of Pennsville Township, New Jersey, Pennsville and Carneys Point Township, New Jersey, Carneys Point townships in Salem County, New Jersey, Salem County, east of the Delaware Memorial Bridge. Its original northern terminus was at an interchange with Interstate 80 in New Jersey , I-80 and U.S. Route 46, US 46 in Ridgefield Park, New Jersey, Ridgefield Park, Bergen County, New Jersey, Bergen County; the turnpike was later extended to t ...

Bus Rapid Transit
Bus rapid transit (BRT), also called a busway or transitway, is a bus-based public transport system designed to have much more capacity, reliability and other quality features than a conventional bus system. Typically, a BRT system includes roadways that are dedicated to buses, and gives priority to buses at intersections where buses may interact with other traffic; alongside design features to reduce delays caused by passengers boarding or leaving buses, or paying fares. BRT aims to combine the capacity and speed of a light rail or metro system (LRT, HRT) with the flexibility, lower cost and simplicity of a bus system. The world's first BRT system was the Busway in Runcorn New Town, England, which entered service in 1971. , a total of 166 cities in six continents have implemented BRT systems, accounting for of BRT lanes and about 32.2 million passengers every day. The majority of these are in Latin America, where about 19.6 million passengers ride daily, and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyeongbu Expressway Bus Only Lane
The name Gyeongbu refers to the Seoul-Busan corridor in South Korea. It is used as the name of the Gyeongbu railway line and Gyeongbu Expressway, both of which connect Seoul—the South Korean capital and largest city—to Busan—the largest port and second-largest city. The name "Gyeongbu" is formed from the first characters in the names "Gyeongseong" 경성 () and "Busan" 부산 ().

Ramp Meter
A ramp meter, ramp signal, or metering light is a device, usually a basic traffic light or a two-section signal light (red and green only, no yellow) together with a signal controller, that regulates the flow of traffic entering freeways according to current traffic conditions. Ramp meters are used at freeway on-ramps to manage the rate of automobiles entering the freeway. Ramp metering systems have proved to be successful in decreasing traffic congestion and improving driver safety. Ramp meters are claimed to reduce congestion (increase speed and volume) on freeways by reducing demand and by breaking up platoons of cars. Two variations of demand reduction are commonly cited; one being access rate, the other diversion. Some ramp meters are designed and programmed to operate only at times of peak travel demand; during off-peak times, such meters are either showing a steady green or are turned off altogether. This allows traffic to merge onto the freeway without stopping. Other r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traffic Flow
In mathematics and transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems. History Attempts to produce a mathematical theory of traffic flow date back to the 1920s, when Frank Knight first produced an analysis of traffic equilibrium, which was refined into John Glen Wardrop, Wardrop's first and second principles of equilibrium in 1952. Nonetheless, even with the advent of significant computer processing power, to date there has been no satisfactory general theory that can be consistently applied to real flow conditions. Current traffic models use a mixture of empirical and Deductive reasoning, theoretical techniques. These models are then developed into Trans ...
