Kilkenny Central Access Scheme (CAS), previously Kilkenny Inner Relief Road Scheme is a controversial new road, improvement of existing roads and junctions and a new concrete bridge over the River Nore later named St. Francis Bridge, with provisions for footpaths and cycle lanes throughout.
 CAS comprises 4.5 kilometers of single carriageway road that is 7.3 metres wide.
 The scheme proved to be controversial as the route of the completed road will bring heavy traffic through residential areas, also the route will bring heavy traffic through the centre of medieval Irishtown section of the city.
Fairbairn Avenue is a major arterial road in the eastern suburbs of Canberra, the capital city of Australia.
 The road travels from a junction with Pialligo Avenue near Canberra Airport to the Australian War Memorial, a distance of 4.2 km .
 It is the primary access route to the Australian Defence Force Academy, Campbell Park and Mount Ainslie.
 Fairbairn Avenue carries the Alternative National Highway 23 designation for a short distance between Majura Road and Morshead Drive.
 This eastern section suffers from heavy traffic congestion during morning and afternoon peak periods and a number of recent upgrades aim to address this.
 In 2009, works to improve access and traffic flows around the airport precinct saw Fairbairn Avenue duplicated between Pialligo Avenue - where an existing roundabout was replaced with traffic lights - and Morshead Drive, also improving the intersection with Majura Road.
 As of 2013, major roadworks are underway which will see a grade separated interchange constructed over Fairbairn Avenue as part of the Majura Parkway project, due for completion in 2016.
Bundesautobahn 57 (translates from German as "Federal Motorway 57", short form Autobahn 57, abbreviated as BAB 57 or A 57) is a German Autobahn that begins at the Dutch-German border near Goch and ends in Köln.
 It runs parallel to the Rhine River.
 Neuss and Krefeld are the biggest cities at this motorway.
 The A 57 is continuation of the Dutch A77.
 Because of its high economic importance, its nickname is "Trans-Niederrhein-Magistrale".
 Most of it is two lanes each way only and prone to traffic jams in the rush hour.
 Currently the sections junction 15 - 18, 19 - 24 and 29 - 30 have three lanes each way.
 The section from junction 28 to 29 southbound has the possibility to open the hard shoulder as a third lane in heavy traffic.
 Traffic jams are possible between junctions 10 and 15, 17 and 20 as well as around junctions 27/28.
 There is a variable speed limit between junction 10 and 23.
 The sections from junction 23 to 24 and 27 to 30 have a limit of 100 km/h.
 Between junctions 27 and 28 the limit was reduced to 80 km/h between 10pm and 6am at night.
Ray Shanklin is a composer.
 Along with Ed Bogas, he co-composed the scores for Ralph Bakshi's films "Fritz the Cat" and "Heavy Traffic".
Heavy Traffic OST is the soundtrack to Ralph Bakshi's 1973 film "Heavy Traffic".
 The film's score was performed by Ed Bogas and Ray Shanklin.
 The soundtrack album was released on Fantasy Records in 1973.
 The album was released on compact disc in 1996 as part of a compilation that featured both the soundtracks to "Fritz the Cat" and "Heavy Traffic" on the same disc.
Fritz the Cat is a 1972 American adult animated comedy film written and directed by Ralph Bakshi.
 It was Bakshi's feature film debut and is loosely based on the Fritz the Cat comic strips by Robert Crumb.
 It was the first animated feature film to receive an X rating in the United States.
Cool and the Crazy is a 1994 American drama film written and directed by Ralph Bakshi and starring Jared Leto and Alicia Silverstone.
 The story revolves around an unhappily married couple in the late 1950s who both lead separate affairs.
 The film was Bakshi's first feature-length live-action film, being primarily known as a director of animated films which heavily utilize live-action sequences, such as "Fritz the Cat", "Heavy Traffic", "Wizards", "American Pop" and "The Lord of the Rings".
Heavy Traffic is a 1973 American adult animated comedy-drama film written and directed by Ralph Bakshi.
 The film, which begins, ends, and occasionally combines with live-action, explores the often surreal fantasies of a young New York cartoonist named Michael Corleone, using pinball imagery as a metaphor for inner-city life.
 "Heavy Traffic" was Bakshi and producer Steve Krantz's follow-up to the film "Fritz the Cat".
 Though producer Krantz made varied attempts to produce an R-rated film, "Heavy Traffic" was given an X rating by the MPAA.
 The film received positive reviews and is widely considered to be Bakshi's biggest critical success.
In queueing theory, a discipline within the mathematical theory of probability, a heavy traffic approximation (sometimes heavy traffic limit theorem or diffusion approximation) is the matching of a queueing model with a diffusion process under some limiting conditions on the model's parameters.
 The first such result was published by John Kingman who showed that when the utilisation parameter of an M/M/1 queue is near 1 a scaled version of the queue length process can be accurately approximated by a reflected Brownian motion.
Peshawar Northern Bypass (Urdu: پشاور شمالی بائی پاس) or Northern Peshawar Highway is a [E-2] dual carriageway, grade separated road with controlled-access, designed for high speeds vehicles and heavy traffic coming from southern Pakistan.
 The bypass has two traffic lanes and an emergency lane in each carriageway.
 It bypasses the Provincial capital Peshawar from north with the purpose to carry the transit traffic bound toward Afghanistan, which has to pass through the city or via the Peshawar ring road.
