Segovia

Redondela De Galicia

Segovia (, also US: , Spanish: [seˈɣoβja] ) is a city in the autonomous region of Castile and León, Spain. The city is famous for its historic buildings including the three main landmarks: its midtown Roman aqueduct, its cathedral (one of the last Gothic to be built in Europe), and the castle, which was an influence for Walt Disney's Cinderella Castle. The city center of Segovia was declared World Heritage by UNESCO in 1985. It is the capital of Province of Segovia.

A roundabout (also called a road circle, rotary, rotunda or island) is a type of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.Modern roundabouts observe various design rules to increase safety. Compared to stop signs, traffic signals, and earlier forms of roundabouts, modern roundabouts reduce the likelihood and severity of collisions greatly by reducing traffic speeds and minimizing T-bone and head-on collisions. Variations on the basic concept include integration with tram and/or train lines, two-way flow, higher speeds and many others. Traffic exiting the roundabout comes from one direction, rather than three, simplifying the pedestrian's visual environment. Traffic moves slowly enough to allow visual engagement with pedestrians, encouraging deference towards them. Other benefits include reduced driver confusion associated with perpendicular junctions and reduced queuing associated with traffic lights. They allow U-turns within the normal flow of traffic, which often are not possible at other forms of junction. Moreover, since vehicles on average spend less time idling at roundabouts than at signalled intersections, using a roundabout potentially leads to less pollution. When entering vehicles only need to give way, they do not always perform a full stop; as a result, by keeping a part of their momentum, the engine will produce less work to regain the initial speed, resulting in lower emissions. Research has also shown that slow moving traffic in roundabouts makes less noise than traffic that must stop and start, speed up and brake.Modern roundabouts were first standardised in the UK in 1966 and were found to be a significant improvement over previous traffic circle and rotaries. Since then they have spread and modern roundabouts are commonplace throughout the world. Half of the world's roundabouts are in France (more than 30,000 as of 2008), although the United Kingdom has more as a proportion of the road than any other country.
