Bourne High School is a public high school located in Bourne, Massachusetts .
52-580: Bourne High School is located about 1 mile west of the famous Bourne Bridge and "Cape Cod" topiary at the Bourne Bridge rotary that welcomes people crossing the Cape Cod Canal . Bourne High School's mascot is the Canalman and the school colors are Purple and White. According to Massachusetts Department of Elementary and Secondary Education annual statistics, for the 2022-23 academic year,
104-416: A pedestrian island for protection that also forces drivers to slow and begin to change direction, encouraging slower, safer speeds. On the island, the pedestrian crossing may become diagonal, to direct the gaze of those crossing into exiting traffic. Physically separated bikeways best protect cyclists. Less optimally, terminating cycle lanes well before roundabout entrances requires cyclists to merge into
156-549: A rotary and a traffic circle are types 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. In the USA, engineers use the term modern roundabout to refer to junctions installed after 1960 that incorporate various design rules to increase safety. Compared to stop signs, traffic signals, and earlier forms of roundabouts, modern roundabouts reduce
208-599: A 616-foot (188 m) main span, with a 135-foot (41 m) ship clearance. Construction ended in early 1935 and the bridge opened on June 22, 1935. The approaches to the main span of the Bourne Bridge are considerably longer than those of the Sagamore Bridge due to the topography of the land. The bridge replaced an earlier 1911 bascule bridge (drawbridge), the Bourne Highway Bridge , the original approaches of which are still accessible. The current structure
260-468: A maximum of six inches (15 cm) apart; the tops of the picket are bent on a seven-inch (18 cm) radius toward the roadway. In the 28-year period after the new fencing was installed (1984–2012), seven persons are known to have died by suicide from the bridges, and during 2013–2021, two attempts were prevented. The fencing was cited in 2021 as a possible model for bridges in Rhode Island . On
312-410: A roundabout can reduce delays, because half of the time a full stop would be required. Dedicated left turn signals (in countries where traffic drives on the right) further reduce throughput. Roundabouts can reduce delays for pedestrians compared to traffic signals, because pedestrians are able to cross during any safe gap rather than waiting for a signal. During peak flows when large gaps are infrequent,
364-729: A significant improvement, in terms of both operations and safety, when compared with older rotaries and traffic circles. The design became mandatory in the United Kingdom for all new roundabouts in November 1966. Australia and other British-influenced countries were the first outside the UK to build modern roundabouts. In the United States modern roundabouts emerged in the 1990s after years of planning and educational campaigning by Frank Blackmore and Leif Ourston , who sought to bring
416-409: A stop and a 90-degree turn to enter. Because these circumstances caused a lot of vehicle collisions, construction of traffic circles and rotaries ceased in the 1950s, and some were removed. Widespread use of the modern roundabout began when the UK's Transport Research Laboratory engineers re-engineered and standardised circular intersections during the 1960s. Frank Blackmore led the development of
468-514: A tree or tall shrubs. Road signage or flagpoles may be erected at the top of a landscaped mound. Some communities use the island for monuments, the display of large public art or for a fountain. Pedestrians may be prohibited from crossing the circling lane(s). Access to the central island requires an underpass or overpass for safety. Roundabouts have attracted art installations around the world: For larger roundabouts, pedestrian islands at each entry/exit encourage drivers to slow and prepare to enter
520-552: Is a stub . You can help Misplaced Pages by expanding it . Bourne Bridge The Bourne Bridge in Bourne, Massachusetts , carries Route 28 across the Cape Cod Canal , connecting Cape Cod with the rest of Massachusetts . It won the American Institute of Steel Construction 's Class "A" Award of Merit as the "Most Beautiful Steel Bridge" in 1934. Most traffic approaching from the west follows Route 25 which ends at
572-516: Is a six-foot-wide (1.8 m) sidewalk for pedestrian and bicycle access on the west side of the bridge. The sidewalk is slightly raised, but there is no fence or barrier between it and car traffic, and cyclists are recommended to walk their bicycle. The bridge road is plowed in winter, although the sidewalk is sometimes unplowed and unpassable. Bridges to the Cape are sometimes closed for safety during high winds. Roundabout A roundabout ,
SECTION 10
#1732798249398624-414: Is a type of looping junction in which road traffic travels in one direction around a central island and priority is given to the circulating flow. Signs usually direct traffic entering the circle to slow and to give way to traffic already on it. Because low speeds are required for traffic entering roundabouts, they are physically designed to slow traffic entering the junction to improve safety, so that
676-404: Is clear without waiting for a signal to change. Roundabouts can increase delays in locations where traffic would otherwise often not be required to stop. For example, at the junction of a high-volume and a low-volume road, traffic on the busier road would stop only when cross traffic was present, otherwise not having to slow for the roundabout. When the volumes on the roadways are relatively equal,
728-633: Is in common use. In the Channel Islands a third type of roundabout, known as "Filter in Turn", exists. Here approaching drivers neither give way to traffic on the roundabout, as normal, nor have priority over it, but take it in turns to enter from each. Almost all of Jersey 's roundabouts are of this type. In the Philippines , the term rotunda or rotonda is used in referring to roundabouts. The fundamental principle of modern roundabouts
780-501: Is known for its strong boys' hockey teams and girls volleyball teams, which have won and participated in multiple state championship games. They play their home games at the John Gallo Arena , which hosts many of the state's post-season high school hockey games. Hockey Accomplishments Also notable is the girls' Volleyball team, who won state championships in 2000, 2004, 2018, and 2024. The football team went undefeated in
832-476: Is that entering drivers give way to traffic within the roundabout without the need for traffic signals. Conversely, older traffic circles typically require circling drivers to give way to entering traffic. Roundabouts may also have an interior lane. Generally, exiting directly from an inner lane of a multi-lane roundabout is permitted, given that the intersecting road has as many lanes as the roundabout. By contrast, exiting from an inner lane of an older traffic circle
884-424: Is the controversy for drivers that seasoned driving teachers complain about this discomfort a decade after its safety is proven and adoption widespread. The central island may be surrounded by a truck apron that is high enough to discourage drivers from crossing over it, but low enough to allow wide or long vehicles to navigate the roundabout. The island may provide a visual barrier, to alert approaching drivers to
936-497: Is usually not permitted and traffic must first move into the outside lane. Vehicles circulate around the central island in one direction at speeds of 25–40 km/h (15–25 mph). In left-hand traffic countries they circulate clockwise (looking from above); in right-hand traffic, anticlockwise. Multi-lane roundabouts are typically less than 75 metres (250 ft) in diameter; older traffic circles and roundabout interchanges may be considerably larger. Roundabouts are roughly
988-401: The "priority rule" and subsequently invented the mini-roundabout to overcome capacity and safety limitations. The priority rule was found to improve traffic flow by up to 10%. In 1966, the United Kingdom adopted a rule at all circular junctions that required entering traffic to give way to circulating traffic. A Transportation Research Board guide reports that the modern roundabout represents

1092-781: The United Kingdom in the 1960s. In the mid-2010s, about 3% of the then circa 4,000 U.S. modern roundabouts were located in Carmel, Indiana , whose mayor James Brainard had been actively promoting their construction; because of increased safety, injuries caused by car accidents in the city dropped by 80% after 1996. As of December 2015 there were about 4,800 modern roundabouts in the United States. As an example, Washington state contained about 120 roundabouts as of October 2016 , all having been built since 1997, with more planned. The first Canadian traffic circles were in Edmonton. There were 7 such by 1954. However, they didn't gain popularity in

#17327982493981144-401: The United Kingdom. A roundabout is also a traditional English name given to amusement rides known as a carousel , or a merry-go-round in other English-speaking countries. In U.S. dictionaries the terms roundabout , traffic circle , road circle and rotary are synonyms. However, several experts such as Leif Ourston have stressed the need to distinguish between the characteristics of
1196-826: The approaches. Many traffic circles have been converted to modern roundabouts, including the former Kingston traffic circle in New York and several in New Jersey. Others have been converted to signalised intersections, such as the Drum Hill Rotary in Chelmsford, Massachusetts , which is now six lanes wide and controlled by four separate intersections. Japan was first introduced to roundabouts in September 2014 to stop major accidents and traffic jams. The word roundabout dates from early 20th-century use in
1248-709: The by then well-established increased safety and traffic flow in other countries to America. The first was constructed in Summerlin, Nevada , in 1990 and was followed by another the following year. This roundabout occasioned dismay from residents, and a local news program said about it, "Even police agree, [roundabouts] can be confusing at times." Between 1990 and 1995, numerous modern roundabouts were built in California, Colorado, Florida, Maryland, Nevada, and Vermont. Municipalities introducing new roundabouts often were met with some degree of public resistance, just as in
1300-496: The circle. They also provide a refuge where pedestrians may pause mid-crossing. Vehicles or bicycles entering or exiting the roundabout must yield to all traffic including pedestrians. Pedestrian crossings at each entry/exit may be located at least one full car length outside the circle. The extra space allows pedestrians to cross behind vehicles waiting to enter the circle, and to allow exiting vehicles to stop for pedestrians without obstruction. Each pedestrian crossing may traverse
1352-520: The demographic enrollment distributions for race, gender and grade level at Bourne High School are as follows: Total number of enrolled students: 351 Total number of full-time equivalent educators: 36.6 Therefore, the student to teacher ratio for this school is 9.6:1 * Approximate number of enrolled pupils is calculated based on total number of students in district, multiplied by reported percentage, and rounded to nearest whole student. * SP = Special Education Beyond Grade 12 Bourne
1404-455: The engine will require 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 circles and rotaries. Since then, modern roundabouts have become commonplace throughout
1456-558: The exit arms of the motorised roundabout, priority must be established. In the Netherlands, cyclists will normally be given priority to promote cycling over driving. As well as their use in the Netherlands and Denmark, these designs have been subsequently built in the United Kingdom and Ireland. The capacity of a roundabout varies based on entry angle, lane width, and the number of entry and circulating lanes. As with other types of junctions, operational performance depends heavily on
1508-449: The flow volumes from various approaches. A single-lane roundabout can handle approximately 20,000–26,000 vehicles per day, while a two-lane design supports 40,000 to 50,000. Under many traffic conditions, a roundabout operates with less delay than signalised or all-way stop approaches. Roundabouts do not stop all entering vehicles, reducing both individual and queuing delays. Throughput further improves because drivers proceed when traffic
1560-639: The interchange with US 6 and Route 28 just north of the bridge. The highway provides freeway connections from Interstate 495 and Interstate 195 . The bridge and its sibling the Sagamore Bridge were constructed beginning in 1933 by the Public Works Administration for the United States Army Corps of Engineers , which operates both the bridges and the canal. Each bridge carries four lanes of traffic over
1612-673: 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 or train lines, two-way flow, higher speeds and many others. For pedestrians, traffic exiting the roundabout comes from one direction, instead of 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

1664-475: The mainland side, New York Central Tugboat 16 sat on dry land at the approach to the bridge from the rotary from 1982 to 2006, serving as a local attraction. In October 2019, the Army Corps of Engineers recommended replacing the bridge with a wider bridge with four travel lanes, one auxiliary lane in each direction, bike and pedestrian paths, shoulders, and a median. The recommendation said that replacement
1716-435: The modern roundabout and the nonconforming traffic circle: The U.S. Department of Transportation adopted the term modern roundabout to distinguish those that require entering drivers to give way to others. Many old traffic circles remain in the northeastern US . Some modern roundabouts are elongated to encompass additional streets, but traffic always flows in a loop. In the United States, traffic engineers typically use
1768-545: The most, by -47% to -84% for the aforementioned heights. The level of irritation to drivers is not to be understated, as it is the crucial point of the design: to force drivers to pay attention to the sides of the driving direction. This leads to drivers complaining about these designs, as Denmark in most regards embraces designing road infrastructure, such that the wanted driving behaviour leads to comfort i.e., lane width corresponding to speed limit and obstacles encouraging slowdown near points of safety concern such as schools. Such
1820-405: The normal flow of traffic, which often are not possible at other forms of junction. Moreover, since vehicles that run on gasoline typically 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,
1872-460: The obstacles have been found to discomfort drivers more so than the roundabout itself compared to conventional intersections, thus initiating further observation and care taking of the driver. In Denmark, it was found to decrease accidents in roundabouts by 27% to 84% depending on height and type. In studies, heights of 0-0.9, 1-1.9 and 2+ metres were evaluated. It was found that for all heights, especially accidents leading to human injuries were reduced
1924-427: The path of an exiting vehicle is relatively straight, and so the motorist may often not slow substantially. To give way to a cyclist on the outside requires the exiting motorist to look toward the rear, to the perimeter. Other vehicles can obstruct the driver's view in this direction, complicating the motorist's task. The more frequent requirements for motorists to slow or stop reduce traffic flow. A 1992 study found that
1976-400: The presence of the roundabout, and to encourage drivers to focus on the traffic in the path of the circle. A visual barrier significantly reduces the accident rate. Otherwise, vehicles anywhere in or near the circle can cause those entering to stop and wait for them to pass, even if they are opposite, which unnecessarily reduces traffic flow. The barrier may be a landscaped mound, a raised wall,

The 2023-24 Boys' Basketball team lost in
2080-586: The rest of the country until the 1990s. They became increasingly popular amongst traffic planners and civil engineers in the 15 years thereafter due to their success in Europe. By 2014 there were about 400 roundabouts in Canada at the time (most in Quebec, Alberta, British Columbia and Ontario), or one per 90,000 inhabitants (compared to one per 84,000 inhabitants in the United States that year). A " modern roundabout"
2132-559: The risk to cyclists is high in all such intersections, but much higher when the junction has a marked bicycle lane or sidepath around its perimeter. Cycle lanes were installed at Museum Road, Portsmouth , but were replaced by a narrowed carriageway to encourage lane sharing. The roundabout at the Brown Road and Loop 202 interchange in Mesa, Arizona , adopts a U.S.-recommended design. On-street pavement markings direct cyclists to enter

2184-483: The roads typically approach the junction radially ; whereas older-style traffic circles may be designed to try to increase speeds, and have roads that enter the circle tangentially . Roundabouts are normally not used on controlled-access highways because of the low speed requirement, but may be used on lower grades of highway such as limited-access roads . When such roads are redesigned to incorporate roundabouts, traffic speeds must be reduced via tricks such as curving
2236-614: The rotary always has the right of way. For instance, in Massachusetts , "Any operator of a vehicle entering a rotary intersection shall yield the right-of-way to any vehicle already in the intersection." In Rhode Island entering vehicles "Yield to vehicles in the roundabout." In the dialect used in the Scottish city of Dundee , circle is used to refer to roundabouts. In the English West Midlands , island
2288-436: The same size as signalled intersections of the same capacity. Design criteria include: Modern roundabouts feature a central island and sometimes pedestrian islands at each entry or exit often for decoration. Denmark has begun widespread adoption of particular high islands, or if not possible, obstacles such as hedges or a ring of trees in larger examples. This is done to further increase the safety benefits of roundabouts, as
2340-488: The sidewalk at the end of the bike lane. Cyclists who choose to travel on the wide sidewalk, cross roundabout arms perpendicularly, well outside the circle. A pedestrian island allows pedestrians and cyclists to cross one lane at a time. Protected roundabouts (or Dutch roundabout) were developed in the Netherlands , with cyclists separated from vehicles using dedicated lanes. As cyclists will conflict with motorists at
2392-616: The slower speed of traffic entering and exiting can still allow crossing, despite the smaller gaps. Studies of roundabouts that replaced stop signs and/or traffic signals found that vehicle delays were reduced 13–89 percent and the proportion of vehicles that stopped was reduced 14–56 percent. Delays on major approaches increased as vehicles slowed to enter the roundabouts. Roundabouts have been found to reduce carbon monoxide emissions by 15–45 percent, nitrous oxide emissions by 21–44 percent, carbon dioxide emissions by 23–37 percent and hydrocarbon emissions by 0–42 percent. Fuel consumption
2444-407: The stream of motor traffic, but keeps cyclists in full view of drivers, at some cost in motor vehicle speed. Cyclists may also be permitted to use pedestrian crossings. Traditional cycle lanes increase vehicle–bicycle collisions. When exiting, a motorist must look ahead to avoid colliding with another vehicle or with pedestrians on a pedestrian crossing. As the intersection curves away from the exit,
2496-432: The term rotary for large-scale circular junctions between expressways or controlled-access highways . Rotaries of this type typically feature high speeds inside the circle and on the approaches. In the United States' New England region, however, a " rotary " is typically used as the general term for all roundabouts, including those with modern designs. State laws in these states mandate that traffic already driving in
2548-605: The world, including Australia, the United Kingdom and France. Circular junctions existed before roundabouts, including: Although some may still be referred to as roundabouts , the operating and entry characteristics of these traffic circles differed considerably from modern roundabouts. Circular intersections were built in the United States, though many were large-diameter 'rotaries' that enabled high-speed merge and weave manoeuvres. Older-style traffic circles may control entering traffic by stop signs or traffic lights. Many allow entry at higher speeds without deflection, or require
2600-599: Was built to accommodate the widening of the canal. The bridge commences at a major rotary on the Cape Cod end. Between 1967 and 1977, 36 persons were recorded as having died by suicide from the Bourne and Sagamore bridges, and another 24 had attempted but either survived or were apprehended. From 1979 to 1983, as part of "major rehabilitation work," both of the bridges' four-foot high railings were replaced with suicide deterrent fencing. The 12-foot-high (3.7 m) fencing consists of one-inch (2.5 cm) round pickets spaced
2652-473: Was more cost-effective than upgrading the existing bridge in order to reduce long summertime backups. The Massachusetts DOT is following up on the 2019 study about the future of the bridge along with the Sagamore Bridge. The 2019 study concluded that improvements were needed to connectivity across the canal. The Cape Cod Bridges program is currently taking public input into the multi phased project and have unveiled different design types for feedback. There
