Circus vs. Roundabout

Main Difference

The main difference between Circus and Roundabout is that the Circus is a commonly a travelling company of performers and Roundabout is a traffic intersection.

• Circus

  A circus is a company of performers who put on diverse entertainment shows that may include clowns, acrobats, trained animals, trapeze acts, musicians, dancers, hoopers, tightrope walkers, jugglers, magicians, unicyclists, as well as other object manipulation and stunt-oriented artists. The term circus also describes the performance which has followed various formats through its 250-year modern history. Philip Astley is credited with being the father of the modern circus when he opened the first circus in 1768 in England. A skilled equestrian, Astley demonstrated trick riding, riding in a circle rather than a straight line as his rivals did, and thus chanced on the format which was later named a “circus”. In 1770 he hired acrobats, tightrope walkers, jugglers and a clown to fill in the pauses between acts. Performances developed significantly through the next fifty years, with large-scale theatrical battle reenactments becoming a significant feature. The traditional format, whereby a ringmaster introduces a varied selection of acts that mostly perform choreographed acts to traditional music, developed in the latter part of the 19th century and continued almost universally to be the main style of circus up until the 1970s.

  As styles of performance have developed since the time of Astley, so too have the types of venues where these circuses have performed. The earliest modern circuses were performed in open air structures with limited covered seating. From the late 18th to late 19th century, custom-made circus buildings (often wooden) were built with various types of seating, a centre ring, and sometimes a stage. The traditional large tents, commonly known as “Big Tops” were introduced in the mid-19th century as touring circuses superseded static venues. These tents eventually became the most common venue and remain so to the present day. Contemporary circuses perform in a variety of venues including tents, theatres and casinos. Many circus performances are still held in a ring usually 13 m (42 ft) in diameter. This dimension was adopted by Astley in the late 18th century as the minimum diameter that enabled an acrobatic horse rider to stand upright on a cantering horse to perform their tricks.

  Contemporary circus has been credited with reviving the circus tradition since the 1980s when a number of groups introduced circuses based almost solely on human skills and which drew from other performing art skills and styles.

• Roundabout

  A roundabout (also called a traffic circle, 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.
