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 19km 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 nor ...

Three-level Diamond Interchange
A three-level diamond interchange is a type of highway Interchange (road), interchange where through traffic on both main roads is Grade separation, grade-separated from intersections which handle transferring traffic. It is similar in design to a Roundabout#Motorways, three-level stacked roundabout except for its use of (usually signalled) Intersection (road), conventional intersections, and can be thought of as two diamond interchanges fused together. Roadgeek, 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Hokkien ( , ) is a Varieties of Chinese, variety of the Southern Min group of Chinese language, Chinese languages.

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 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 light, traffic signals. Due to the space efficiency of SPUIs relative to the volume of traffic they can handle, the interchange design is used extensively in the reconstruction of existing freeways as well as constructing new freeways, p ...

Diamond Interchange
A diamond interchange is a common type of road junction, used where a controlled-access highway crosses a minor road. Design The freeway itself is grade separation, grade-separated from the minor road, one crossing the other over a bridge. Approaching the interchange (road), interchange from either direction, an off-ramp diverges only slightly from the freeway and runs directly across the minor road, becoming an on-ramp that returns to the freeway in similar fashion. The two places where the Interchange (road), ramps meet the road are treated as conventional intersection (road), intersections. In the United States, where this form of interchange is very common, particularly in rural areas, traffic on the off-ramp typically faces a stop sign at the minor road, while traffic turning onto the freeway is unrestricted. The diamond interchange uses less space than most types of freeway interchange, and avoids the grade separation#Weaving, interweaving traffic flows that occur i ...

Traffic Signals
Traffic lights, traffic signals, or stoplights – also known as robots in South Africa, Zambia, and Namibia – are signaling devices positioned at intersection (road), road intersections, pedestrian crossings, and other locations in order to control the flow of traffic. Traffic lights usually consist of three signals, transmitting meaningful information to road users through colours and symbols, including arrows and bicycles. The usual traffic light colours are red to stop traffic, Amber (color), amber for traffic change, and green to allow traffic to proceed. These are arranged vertically or horizontally in that order. Although this is internationally standardised, variations in traffic light sequences and laws exist on national and local scales. Traffic lights were first introduced in December 1868 on Parliament Square in London to reduce the need for police officers to control traffic. Since then, electricity and computerised control have advanced traffic light technolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade-separated
In civil engineering (more specifically highway engineering), grade separation is a method of aligning a junction of two or more surface transport axes at different heights ( grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges (or overpasses, also called flyovers), tunnels (or underpasses), or a combination of both can be built at a junction to achieve the needed grade separation. In North America, a grade-separated junction may be referred to as a ''grade separation'' or as an '' interchange'' – in contrast with an ''intersection'', '' at-grade'', a '' diamond crossing'' or a ''level crossing'', which are not grade-separated. Effects Advantages Roads with grade separation generally allow traffic to move freely, with fewer interruptions, and at higher over ...
