Road sign in Dubai. Road signs in United Arab Emirates are modelled on the British road sign system [1]: 433 that are regulated by the Roads and Transport Authority (RTA) Dubai and Department of Transport (DoT) Abu Dhabi.
A comparison between a two-lane roundabout and a turboroundabout showing possible collision points. According to simulations, a two-lane roundabout with three exits should offer 12–20% greater traffic flow than a conventional, three-lane roundabout of the same size. The reason is reduced weaving that makes entering and exiting more predictable.
The 1931 Convention rules were developed in the 1949 Geneva Protocol on Road Signs and Signals [28] and a European Agreement supplementing the 1949 Protocol. [ 29 ] In 1968, the European countries signed the Vienna Convention on Road Traffic treaty, with the aim of standardizing traffic regulations in participating countries to facilitate ...

Single-lane roundabouts are generally used in the Netherlands. Otherwise, a turbo roundabout can be used, which has multiple lanes and separates motor traffic going in different directions, but multi-lane roundabouts have been found to be especially dangerous to cyclists since many cyclists choose to ride in the outside lane and become much ...
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.
The three-level stacked roundabout is a variation on the roundabout interchange in which both roads are grade-separated. It is similar to the three-level diamond interchange except that the small square of that latter interchange is enlarged to a true roundabout. If the roundabout is sufficiently large, the interchange may require only two ...
The United Arab Emirates (UAE) has an extensive and well-developed road network, principally in the northern coastal area where the main population centres are located. Many of these roads have been improved to become multi-lane dual-carriageway motorways, coping with the high demand for road transportation. The UAE has a right hand traffic ...
