A continuous flow intersection (CFI), also called a crossover displaced left-turn (XDL or DLT), is an alternative design for an at-grade road junction. Vehicles attempting to turn across the opposing direction of traffic (left in right-hand drive jurisdictions; right in left-hand drive jurisdictions) cross before they enter the intersection.
Channelization is a traffic engineering concept that employs the use of secondary roads, slip lane to separate certain flows of traffic from the main traffic lanes. The method came into favor in the United States in the 1950s.
A geometric design saved on construction costs and improved visibility with the intention to reduce the likelihood of traffic incidents The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints.
One of the examples in Asia includes the Clark South exit in SCTEX, which is a two quadrant parclo interchange. Depending on traffic and land needs, hybrid designs, such as the parclo AB and parclo A3, can be created. A notable example of a parclo AB interchange includes the Highway 417 and the Woodroffe Avenue interchange in Ottawa. Other ...
Question: I was recently told by a friend that the proper way to make a left-hand turn at a stop light was to proceed into the intersection when the light turns green, then wait until oncoming ...
A Michigan left or P-turn is an at-grade intersection design that replaces each left (farside) turn at an intersection between a (major) divided roadway and a secondary (minor) roadway with the combination of a right (nearside) turn followed by a U-turn, or a U-turn followed by a right (nearside) turn, depending on the situation. It is in use ...
Instead of a standard left turn being made from the left lane, left-turning traffic uses a ramp on the right side of the road. In a standard forward jughandle or near-side jughandle, the ramp leaves before the intersection, and left-turning traffic turns left off of it rather than the through road; right turns are also made using the jughandle.
An example of a collector-express freeway design, the route features four carriageways through Toronto. The A10 near Orléans, France, showing hard shoulder and emergency telephone. The broken demarcation line for the hard shoulder is specific to France, and serves as a safety reference mark for drivers: the advisory distance from the vehicle ...
