Outer Ring Road System
The Outer Ring Road System, or more commonly known as ORRS, is a network of major arterial roads in Singapore that forms a ring road through the towns along the city fringe. The ORRS is a semi-expressway, just like the West Coast Highway. Since 1994, roads along the ORRS have been upgraded in stages to provide a smoother route to travel across the island. Roads and interchanges along the ORRS are constantly being upgraded to cater to the ever increasing traffic demand. It starts as Portsdown Avenue in Queenstown and ends as Tampines Avenue 10 in Tampines. The series of roads passes through the areas of Queenstown, Bukit Timah, Central Catchment Nature Reserve, Bishan, Toa Payoh, Geylang and Tampines. Route The route of the ORRS forms a semi-circle shape, connecting several expressways and major arterial roads. Travelling from west to east in a clockwise direction, the route begins at Queenstown with a connection to the Ayer Rajah Expressway. The route continues northward thr ...

Trumpet Interchange
In the field of road transport, an interchange (American English) or a grade-separated junction (British English) is a road junction that uses grade separations to allow for the movement of traffic between two or more roadways or highways, using a system of interconnecting roadways to permit traffic on at least one of the routes to pass through the junction without interruption from crossing traffic streams. It differs from a standard intersection, where roads cross at grade. Interchanges are almost always used when at least one road is a controlled-access highway (freeway or motorway) or a limited-access divided highway (expressway), though they are sometimes used at junctions between surface streets. Terminology ''Note:'' The descriptions of interchanges apply to countries where vehicles drive on the right side of the road. For left-side driving, the layout of junctions is mirrored. Both North American (NA) and British (UK) terminology is included. ; Freeway junction, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seagull Intersection
A seagull intersectionJohn Harper, Wal Smart, Michael de Roos''Seagull Intersection Layout. Island Point Road – A Case Study'' 2000 – 2010 or continuous green T-intersection (also known as a turbo-T (in Florida) or High-T intersection (in Nevada and Utah)Nevada DOT''US93 Lakeshore v4 Handouts''/ref>) is a type of three-way road intersection, usually used on high traffic volume roads and dual carriageways. This form of intersection is popular in Australia and New Zealand, and sometimes used in the United States and other countries. Design Seagull intersections get their name from the pattern that the two cross-traffic turn lanes make when looking down at them from the air. In a seagull intersection, one or more lanes of traffic on the arterial road, on the carriageway opposite the intersecting side road, are free flowing, that is, one direction of traffic on the arterial is allowed to travel straight through without stopping. The free-flowing lane(s) are called "continuou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slip Lane
A slip lane, also known as a filter lane in the United Kingdom, is a road at a junction that allows motorists to change roads without actually entering an intersection. Some intersections that are controlled by lights offer a slip lane, which allows cars to bypass the lights when they turn. That helps ease congestion and improves journey times, as people turning do not have to stop at the light but can continue at the same speed. There are two types of slip lanes at intersections: slip lanes that end and require traffic to merge to join the main road and slip roads that continue onto the main road as another traffic lane. Rules In Australia, before entering a slip road, drivers must look to ensure that their blind spots are clear of other motorists, cyclists, and pedestrians. Drivers must then give way to any pedestrians crossing the slip road. Before joining the main road from a slip road, drivers must give way to all other traffic even if it is faced with a give-way or with o ...

Parclo
A partial cloverleaf interchange or parclo is a modification of a cloverleaf interchange. The design has been well received, and has since become one of the most popular freeway-to-arterial interchange designs in North America. It has also been used occasionally in some European countries, such as Germany, Hungary, Italy, the Netherlands, and the United Kingdom. Comparison with other interchanges *A diamond interchange has four ramps. *A cloverleaf interchange has eight ramps, as does a stack interchange. They are fully grade separated, unlike a parclo, and have traffic flow without stops on all ramps and throughways. *A parclo generally has either four or six ramps but less commonly has five ramps. Naming In Ontario, the specific variation is identified by a letter/number suffix after the name. Ontario's naming conventions are used in this article. The letter ''A'' designates that two ramps meet the freeway ''ahead'' of the arterial road, while ''B'' designates that two ramp ...

Three-level Diamond Interchange
A three-level diamond interchange is a type of highway interchange where through traffic on both main roads is grade-separated from intersections which handle transferring traffic. It is similar in design to a three-level stacked roundabout except for its use of (usually signalled) conventional intersections, and can be thought of as two diamond interchanges fused together. Road enthusiasts sometimes use the terms volleyball interchange or split-level diamond interchange to refer to these interchanges. Description In a three-level diamond interchange, the two main roads are on separate levels, and on a third level, usually in the middle, there is a square of one-way roads. The square circulates clockwise where traffic drives on the left, or anticlockwise where it drives on the right. At each corner of the square is the terminal of an exit ramp from one main road and an entrance ramp to the other main road. Traffic transferring from one road to the other to make an overall ...

Holland Road, Singapore
Holland Road () is a subzone of the Bukit Timah planning area named after the major road of the same name in Bukit Timah, Singapore. Holland Road is located between the borders of Clementi, Holland Village, a neighborhood along the Queenstown–Bukit Timah boundary, which is popular for its restaurants, cafes and nightspots and is frequented by expatriates. and Dempsey Hill. Etymology Holland Road and Holland Village were named after an early resident in Singapore, Hugh Holland, who was an architect. The roads Holland Avenue, Holland Close and Holland Drive were named as such in 1972. Holland Road is known as ''hue hng au'' in Hokkien, meaning "behind the flower garden". The "flower garden" refers to the Botanic Gardens A botanical garden or botanic gardenThe terms ''botanic'' and ''botanical'' and ''garden'' or ''gardens'' are used more-or-less interchangeably, although the word ''botanic'' is generally reserved for the earlier, more traditional gardens, an ....

Right-in/right-out
Right-in/right-out (RIRO) and left-in/left-out (LILO) refer to a type of three-way road intersection where turning movements of vehicles are restricted. A RIRO permits only right turns and a LILO permits only left turns. "Right-in" and "left-in" refer to turns from a main road ''into'' an intersection (or a driveway or parcel); "right-out" and "left-out" refer to turns ''from'' an intersection (or a driveway or parcel) to a main road. RIRO is typical when vehicles drive on the right, and LILO is usual where vehicles drive on the left. This is because minor roads usually connect to the outsides of two-way roads. However, on a divided highway, both RIRO and LILO intersections can occur. The remainder of this article refers only to RIRO but applies equally to LILO. A RIRO intersection differs from a 3/4 intersection (right in/right out/left in) and an unrestricted intersection. Design RIRO is an important tool of access management, itself an important component of transport ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-point Urban Interchange
A single-point urban interchange (SPUI, or ), also called a single-point interchange (SPI) or single-point diamond interchange (SPDI), is a type of highway interchange. The design was created in order to help move large volumes of traffic through limited amounts of space safely and efficiently. Description A SPUI is similar in form to a diamond interchange but has the advantage of allowing opposing left turns to proceed simultaneously by compressing the two intersections of a diamond into one single intersection over or under the free-flowing road. The term "single-point" refers to the fact that all through traffic on the arterial street, as well as the traffic turning left onto or off the interchange, can be controlled from a single set of traffic signals. Due to the space efficiency of SPUIs relative to the volume of traffic they can handle, the interchange design is being used extensively in the reconstruction of existing freeways as well as constructing new freeways, p ...
