COMPASS, also referred to as Freeway Traffic Management System, is a system run by the Ministry of Transportation of Ontario (MTO) to monitor and manage the flow of traffic on various roads (including 400-series highways) in Ontario.
COMPASS uses pairs of in-road sensors to detect the speed and density of traffic flow. This data is fed to a central computer at the MTO Downsview office and analyzed by operators, who also view the feeds of traffic cameras placed along the highways. Changeable Message Signs (CMS) then display messages to motorists on the highways, advising them of upcoming collisions, closures, detours and traffic flow.
The primary algorithm used by the Ministry is known as the McMaster algorithm, designed by Professor Fred Hall of McMaster University, in Hamilton, Ontario. Incident Detection algorithms have also been widely used throughout the COMPASS-enabled area.
Research on new algorithm developments and evaluations is performed at the ITS Centre and Testbed (ICAT), at the Civil Engineering department of the University of Toronto. The ICAT is equipped with direct fibre-optic links to the Ministry of Transportation, and received both traffic camera and loop detector data on a live basis. Visual data can be used to confirm the presence of incidents detected by the various algorithms.
Images from most COMPASS cameras are available online via MTO website.
COMPASS has some dedicated cameras used by MTO Enforcement Officers to monitor and manage truck queues at locations such as the Putman Commercial Vehicle Inspection Station. Images from these cameras are not available online.
Highways with COMPASS cameras:
(Fort Erie, Niagara Falls to St Catharines, Stoney Creek to Toronto)
(London and Windsor, Milton to Ajax, Kingston, Ivy Lea). One of the highest-volume highways in the world
(Vyner to Sarnia)
(Hamilton to Burlington, Oakville to Mississauga)
(Toronto to Markham)
(Niagara Falls)
(Toronto)
(Mississauga to Brampton)
(the Queensway, Ottawa)
(Toronto)
A false alarm for incident detection is not only highly undesirable, but seriously damages the confidence in the detection system. Therefore, a near 100% alarm accuracy is needed. This does not mean that 100% traffic parameter accuracy is required from the traffic sensors; however, the logical commands that analyze the change in traffic parameters need to be selected carefully in order to minimize the probability of false alarms yet detect all major incidents as well as a high percentage of all other incidents. Most importantly, confirmation of incident and evaluation of incident type by manual inspection of a video camera screen is probably the most significant incident detection technique.
King's Highway 401, commonly referred to as Highway 401 and also known by its official name as the Macdonald–Cartier Freeway or colloquially referred to as the four-oh-one, is a controlled-access 400-series highway in the Canadian province of Ontario. It stretches 828 kilometres (514 mi) from Windsor in the west to the Ontario–Quebec border in the east. The part of Highway 401 that passes through Toronto is North America's busiest highway, and one of the widest. Together with Quebec Autoroute 20, it forms the road transportation backbone of the Quebec City–Windsor Corridor, along which over half of Canada's population resides. It is also a Core Route in the National Highway System of Canada. The route is maintained by the Ministry of Transportation of Ontario (MTO) and patrolled by the Ontario Provincial Police. The speed limit is 100 km/h (62 mph) throughout its length, with the only exceptions being the posted 80 km/h (50 mph) limit westbound in Windsor and in most construction zones, along with a 110 km/h (68 mph) speed limit between Windsor and Tilbury.
King's Highway 407, commonly referred to as Highway 407 and colloquially as the "four-oh-seven", is a tolled 400-series highway in the Canadian province of Ontario. Comprising a privately leased segment as well as a publicly owned segment, the route spans the entire Greater Toronto Area (GTA) around the city of Toronto, travelling through the suburbs of Burlington, Oakville, Mississauga, Brampton, Vaughan, Markham, Pickering, Whitby, and Oshawa before ending in Clarington, north of Orono. At 151.4 km long, this is the fourth-longest freeway in Ontario's 400 series network, after Highways 417, 400, and 401. The segment between Burlington and Brougham in Pickering is leased to and operated by the 407 ETR Concession Company Limited and is officially known as the 407 Express Toll Route (407 ETR). It begins at the junction of the Queen Elizabeth Way (QEW) and Highway 403 in Burlington, and travels 108.0 km (67.1 mi) across the GTA to Brock Road in Pickering. East of Brock Road, the tollway continues east as Highway 407, a toll route operated by the provincial government, for 43.4 km (27.0 mi) to Highway 35/115 in Clarington. The route interchanges with nine freeways: the QEW, Highway 403, Highway 401, Highway 410, Highway 427, Highway 400, Highway 404, Highway 412, and Highway 418. Highway 407 is an electronically operated toll highway; there are no toll booths along the length of the route. Distances are calculated automatically using transponders or automatic number-plate recognition, which are scanned at entrance and exit portals.
The Queen Elizabeth Way (QEW) is a 400-series highway in the Canadian province of Ontario linking Toronto with the Niagara Peninsula and Buffalo, New York. The highway begins at the Canada–United States border on the Peace Bridge in Fort Erie and travels 139.1 kilometres (86.4 mi) around the western end of Lake Ontario, ending at Highway 427 as the physical highway continues as the Gardiner Expressway into downtown Toronto. The QEW is one of Ontario's busiest highways, with an average of close to 250,000 vehicles per day on some sections.
The 400-series highways are a network of controlled-access highways in the Canadian province of Ontario, forming a special subset of the provincial highway system. They are analogous to the Interstate Highway System in the United States or the Autoroute system of neighbouring Quebec, and are regulated by the Ministry of Transportation of Ontario (MTO). The 400-series designations were introduced in 1952, although Ontario had been constructing divided highways for two decades prior. Initially, only Highways 400, 401 and 402 were numbered; other designations followed in the subsequent decades. The network is situated almost entirely in Southern Ontario, although Highway 400 extends into the more remote northern portion of the province.
The Niagara Peninsula is an area of land lying between the southwestern shore of Lake Ontario and the northeastern shore of Lake Erie, in Ontario, Canada. Technically an isthmus rather than a peninsula, it stretches from the Niagara River in the east to Hamilton, Ontario, in the west. The peninsula is located in the Golden Horseshoe region of Southern Ontario, and has a population of roughly 1,000,000 residents. The region directly across the Niagara River and Lake Erie in New York State is known as the Niagara Frontier.
The Provincial Highway Network consists of all the roads in Ontario maintained by the Ministry of Transportation of Ontario (MTO), including those designated as part of the King's Highway, secondary highways, and tertiary roads. Components of the system—comprising 16,900 kilometres (10,500 mi) of roads and 2,880 bridges —range in scale from Highway 401, the busiest highway in North America, to unpaved forestry and mining access roads. The longest highway is nearly 2,000 kilometres (1,200 mi) long, while the shortest is less than a kilometre. Some roads are unsigned highways, lacking signage to indicate their maintenance by the MTO; these may be remnants of highways that are still under provincial control whose designations were decommissioned, roadway segments left over from realignment projects, or proposed highway corridors.
The Regional Municipality of Niagara, also colloquially known as the Niagara Region or Region of Niagara, is a regional municipality comprising twelve municipalities of Southern Ontario, Canada. The regional seat is in Thorold. It is the southern end of the Golden Horseshoe, the largest megalopolis in Canada.
King's Highway 58, commonly referred to as Highway 58, is a provincially maintained highway in the Canadian province of Ontario. The route is divided into two segments with a combined length of 15.5 km (9.6 mi). The southern segment travels from Niagara Regional Road 3, formerly Highway 3, in Port Colborne, to the Highway 58A junction in the southern end of Welland, a distance of 7.2 km (4.5 mi). The northern segment begins at Highway 20 near Allanburg and travels north and west to a large junction with Highway 406 at the St. Catharines – Thorold boundary, a distance of 8.3 km (5.2 mi). An 18.1 km (11.2 mi) gap separates the two segments within Welland and Pelham. The entire route is located within the Regional Municipality of Niagara.
King's Highway 3, commonly referred to as Highway 3, is a provincially maintained highway in the Canadian province of Ontario which travels parallel to the northern shoreline of Lake Erie. It has three segments, the first of which travels from the Ambassador Bridge in Windsor to Highway 77 in Leamington. The second portion begins at Talbotville Royal outside of St. Thomas at Highway 4, and travels to the western city limits of Port Colborne. The road is regionally maintained within Port Colborne as Niagara Regional Road 3, but regains its provincial designation at Highway 140. Its third and final terminus is at Edgewood Park, within the Fort Erie town limits. From there, the road continues as Niagara Regional Road 3 to the Peace Bridge, where drivers can cross to the United States. The total length of Highway 3 is 258.2 km (160.4 mi), consisting of 49.2 km (30.6 mi) from Windsor to Leamington, 187.9 km (116.8 mi) from Talbotville Royal to Port Colborne and 21.1 km (13.1 mi) from Port Colborne to Edgewood Park.
King's Highway 427, also known as Highway 427 and colloquially as the 427, is a 400-series highway in the Canadian province of Ontario that runs from the Queen Elizabeth Way (QEW) and Gardiner Expressway in Toronto to Major Mackenzie Drive in Vaughan. It is Ontario's second busiest freeway by volume and the third busiest in North America, behind Highway 401 and Interstate 405 in California. Like Highway 401, a portion of the route is divided into a collector-express system with twelve to fourteen continuous lanes. Notable about Highway 427 are its several multi-level interchanges; the junctions with the QEW/Gardiner Expressway and Highway 401 are two of the largest interchanges in Ontario and were constructed between 1967 and 1971, while the interchanges with Highway 409 and Highway 407 were completed in 1992 and 1995, respectively.
King's Highway 403, or simply Highway 403, is a 400-series highway in the Canadian province of Ontario that travels between Woodstock and Mississauga, branching off from and reuniting with Highway 401 at both ends and travelling south of it through Hamilton and Mississauga. It is concurrent with the Queen Elizabeth Way (QEW) for 22 km (14 mi) from Burlington to Oakville. The Highway 403 designation was first applied in 1963 to a short stub of freeway branching off the QEW, and the entire route was completed on August 15, 1997, when the section from Brantford to the then-still independent Town of Ancaster was opened to traffic. The section of Highway 403 between Woodstock and Burlington was formally dedicated as the Alexander Graham Bell Parkway on April 27, 2016, in honour of Alexander Graham Bell.
King's Highway 405, also known as Highway 405 and the General Brock Parkway, is a 400-Series Highway in the Canadian province of Ontario connecting the Queen Elizabeth Way (QEW) near St. Catharines with the Lewiston–Queenston Bridge in the village of Queenston. It then crosses the Niagara River, where it encounters the international border with the United States and continues into New York as Interstate 190 (I-190).
King's Highway 406, commonly referred to as Highway 406, is a 400-series highway in the Canadian province of Ontario. The primary north–south route through the central portion of the Niagara Peninsula, Highway 406 connects Welland, Thorold and downtown St. Catharines to the Queen Elizabeth Way (QEW).
King's Highway 420, commonly referred to as Highway 420, is a 400-series highway in the Canadian province of Ontario that connects the Queen Elizabeth Way (QEW) with downtown Niagara Falls. It continues east as a limited-access expressway named Niagara Regional Road 420 to connect with the Rainbow Bridge international crossing between Canada and the United States over the Niagara River; this was part of Highway 420 until 1998. West of the QEW, the freeway ends at an at-grade intersection with Montrose Road. The highway has a speed limit of 80 kilometres per hour (50 mph), making it the only 400-series highway to have a speed limit less than 100 kilometres per hour (62 mph) for its entirety.
The cancelled expressways in Toronto were a planned series of expressways in Toronto, Ontario, Canada that were only partially built or cancelled due to public opposition. The system of expressways was intended to spur or handle growth in the suburbs of Toronto, but were opposed by citizens within the city of Toronto proper, citing the demolition of homes and park lands, air pollution, noise and the high cost of construction. The Spadina Expressway, planned since the 1940s, was cancelled in 1971 after being only partially constructed. After the Spadina cancellation, other expressway plans, intended to create a 'ring' around the central core, were abandoned.
The Garden City Skyway is a major high-level bridge located in St. Catharines and Niagara-on-the-Lake, Ontario, Canada, that allows the Queen Elizabeth Way (QEW) to cross the Welland Canal without the interruption of a lift bridge. Six lanes of traffic are carried across the bridge, which is 2.2 kilometres (1.4 mi) in length and 40 metres (130 ft) at its tallest point.
King's Highway 20, commonly referred to as Highway 20, is a provincially maintained highway in the Canadian province of Ontario. Presently, it is a short 1.9 km (1.2 mi) stub between Highway 58 and Niagara Regional Road 70 in the City of Thorold, but until 1997 it connected Hamilton to Niagara Falls, serving several towns atop the Niagara Escarpment en route.
GO Transit bus services are provided throughout the Greater Toronto and Hamilton Area and the Greater Golden Horseshoe. In 2023, the system had a ridership of 15,229,800.
