What is the difference between stratified and cluster sampling? [1]
What is the difference between stratified and cluster sampling?. Stratified and cluster sampling may look similar, but bear in mind that groups created in cluster sampling are heterogeneous, so the individual characteristics in the cluster vary
Relatedly, in cluster sampling you randomly select entire groups and include all units of each group in your sample. However, in stratified sampling, you select some units of all groups and include them in your sample

Traffic enforcement camera [3]
A traffic enforcement camera (also a red light camera, speed camera, road safety camera, road rule camera, photo radar, photo enforcement, Gatso, safety camera, bus lane camera, flash for cash, Safe-T-Cam, No contact apprehension camera depending on use) is a camera which may be mounted beside or over a road or installed in an enforcement vehicle to detect motoring offenses, including speeding, vehicles going through a red traffic light, vehicles going through a toll booth without paying, unauthorized use of a bus lane, or for recording vehicles inside a congestion charge area. A worldwide review of studies found that speed cameras led to a reduction of “11% to 44% for fatal and serious injury crashes”.[1] The UK Department for Transport estimated that cameras had led to a 22% reduction in personal injury collisions and 42% fewer people being killed or seriously injured at camera sites
An LSE study in 2017 found that “adding another 1,000 cameras to British roads could save up to 190 lives annually, reduce up to 1,130 collisions and mitigate 330 serious injuries.”[2]. The latest automatic number-plate recognition systems can be used for the detection of average speeds and raise concerns over loss of privacy and the potential for governments to establish mass surveillance of vehicle movements and therefore by association also the movement of the vehicle’s owner
Some groups, such as the American Civil Liberties Union in the US, claim that “the common use of speed traps as a revenue source also undercuts the legitimacy of safety efforts.”[3]. Some bus lane enforcement cameras use a sensor in the road, which triggers a number-plate recognition camera, which compares the vehicle registration plate with a list of approved vehicles and records images of other vehicles.[4] Other systems use a camera mounted on the bus, for example in London where they monitor Red routes[5] on which stopping is not allowed for any purpose (other than taxis and disabled parking permit holders).[6]
Internet bandwidth and speed requirements for Nest cameras [4]
Google Nest cameras and doorbells upload video to the cloud, which requires a portion of your internet bandwidth.. – Generally, most internet plans have a lower bandwidth for upload speeds and a high bandwidth for download speeds.
– Download bandwidth is used when you’re accessing information from the internet, such as streaming video or music, or browsing the web.. – Make sure that your internet service plan has enough upload bandwidth to support the number of cameras you have
– Your camera uses your home internet bandwidth to stream live video to the Nest service in the cloud.. – If your camera records video with 24/7 video history or event video history, it streams live video and uses bandwidth whenever it is turned on.
Renewed calls for mobile speed camera warning signs as a year’s worth of fines are issued in a month [5]
Renewed calls for mobile speed camera warning signs as a year’s worth of fines are issued in a month. Mobile speed camera fines in NSW have skyrocketed since portable warning signs disappeared, reflective vehicle markings were removed, and the technology was enabled to catch cars travelling in both directions.
The latest figures show speed camera cars in NSW now earn almost as much in one month as they previously earned in a year.. In the first six months of 2021, mobile speed cameras in NSW issued $28 million in fines versus just $2.9 million for the same period the prior year – an almost tenfold increase.
Of particular concern is the even sharper increase in the number of motorists issued speeding tickets for travelling at less than 10km/h over the posted limit.. The spike in speeding offences less than 10km/h over the posted limit has been driven by numerous factors, say experts, most of which escaped mainstream media attention due to the initial focus on the removal of mobile speed camera warning signs.
Global Road Safety FAQ [6]
Speed management involves various techniques to reduce/modify the speed of road users, usually motorized vehicles. The purpose is to ensure that speeds are safe for all road users to avoid injuries and death, as well as to improve traffic flow, reduce noise and air pollution, and decrease climate change impacts of road transport.
A mixture of these approaches is often used and the most effective. Speed management should occur as part of a structured, consistent approach that covers the entire road network of interest
Under the Safe System approach, safety is the key objective when managing speeds, with a requirement to set and encourage speeds that avoid death and serious injury for all road users, particularly the most vulnerable (including pedestrians and cyclists). Decisions on the appropriate speed often include reference to other societal outcomes besides safety mentioned above, including vehicle journey time, noise and emissions.
Long-Term Effects of Repealing the National Maximum Speed Limit in the United States [7]
Long-Term Effects of Repealing the National Maximum Speed Limit in the United States. We examined the long-term effects of the 1995 repeal of federal speed limit controls on road fatalities and injuries in fatal crashes.
We found a 3.2% increase in road fatalities attributable to the raised speed limits on all road types in the United States. The highest increases were on rural interstates (9.1%) and urban interstates (4.0%)
Reduced speed limits and improved enforcement with speed camera networks could immediately reduce speeds and save lives, in addition to reducing gas consumption, cutting emissions of air pollutants, saving valuable years of productivity, and reducing the cost of motor vehicle crashes.. In 1974, the federal government passed the National Maximum Speed Law, which restricted the maximum permissible vehicle speed limit to 55 miles per hour (mph) on all interstate roads in the United States.1 The law was a response to the 1973 oil embargo, and its intent was to reduce fuel consumption
‘Infuriating and soul killing:’ Toronto’s speed cameras were vandalized 555 times in a year [8]
‘Infuriating and soul killing:’ Toronto’s speed cameras were vandalized 555 times in a year. One speed camera in Bloor West Village was spray painted on 31 different occasions over the span of just a few months last year.
A third camera, in Scarborough’s Highland Creek neighbourhood, was moved by vandals despite weighing hundreds of pounds. These are just some of the 555 incidents of speed camera vandalism reported between June 1, 2022 and May 31, 2023 and detailed in documents obtained by CP24.com through a freedom of information request.
“I find it infuriating and soul killing that people would do this,” Jess Spieker, of Friends and Family For Safe Streets, told CP24.com upon learning of the extent of the vandalism. “I think it says in particular a lot about the toxicity of car culture
Tougher speeding rules could lead to thousands more drivers being caught breaking the limit [9]
Drivers will now face prosecution if they break the limit by 10% plus 2mph. The Metropolitan Police had not directly announced any rule changes to speed tolerance before they came into force.
The Met did state that no matter the threshold, all drivers should stick the speed limits and never exceed them.. According to a report from This Is Money, the new rules could result in more than 347,000 drivers being prosecuted for speeding between January and June this year
The Police force said: “Posted speed limits are the maximum speed that road users should travel at any time irrespective of the speed threshold that police commence enforcement action.”. |Speed Limit (mph)||Variable speed limit (10%+2mph)|
Motorway cameras – what you need to know [10]
From average speed cameras to automatic number plate recognition (ANPR) cameras, there are a number of different types, each with different purposes.. Here we run through the functions of the cameras on our motorways and how they keep our roads safe.
The cameras are frequently used on smart motorways to enforce variable speed limits; and as a result are sometimes called variable speed cameras (differentiating them from SPECS average speed cameras).. These systems are often mounted on poles at the side of the motorway, and are largely painted in grey: only the camera units themselves sometimes receive yellow markings.
They are thus much more efficient than older systems.. The dual radar system is effective in all weathers, and they operate fully digitally for fast processing of speeding penalties.
Chicago’s “Race-Neutral” Traffic Cameras Ticket Black and Latino Drivers the Most [11]
Parking, traffic camera and vehicle tickets generate millions of dollars in desperately needed cash each year for the City of Chicago. But for the working poor, and particularly for African Americans, paying for tickets can be difficult — opening the door to more fines and fees, and spiraling debt
Daley ushered in Chicago’s red-light cameras nearly two decades ago, he said they would help the city curb dangerous driving. “This is all about safety, safety of pedestrians, safety of other drivers, passengers, everyone,” he said.
“My goal is only one thing, the safety of our kids,” Rahm Emanuel said in 2011, as he lobbied for the introduction of speed cameras. And in 2020, Lori Lightfoot assured residents her expansion of the program was “about making sure that we keep communities safe.”
Speed Camera Map [12]
Automated Enforcement is a tool that uses technology to alter driver behaviour by enforcing the applicable traffic law. In the City of Toronto, Automated Enforcement is used to reduce the prevalence of excessive speeding and the running of red lights to improve roadway safety for all road users, especially our most vulnerable (school-aged children, older adults, people on bicycles and motorcyclists)
The speed limit is America’s most broken law. Why can’t we fix it? [13]
One Tuesday morning this fall, I strapped on a Kevlar vest and slid into the passenger seat of a gray Ford Interceptor sedan, the souped-up Taurus that replaced the Crown Vic as America’s default police car a decade ago.* (And has since been replaced itself: Ford no longer produces police cars, only SUVs and pickups.) This model has several features that are not available for civilian use, including a siren on the roof and a V6 Mustang engine under the hood.. That came in handy when Kevin Roberts, a talkative, thoughtful third-year cop, steered us onto Connecticut’s Interstate 84 for the day shift
Roberts was in the left lane going 80, and I had the uncanny experience of surveying the highway from his point of view. How many times have I been on the other side—overtaking some slowpoke, 12 over the limit, only to see a rack of siren lights in the rearview mirror and ask myself: How slowly can I complete this pass?
He knows people resent that the police are always speeding, but he says it’s the only way to do the job. You can’t drive the speed limit or below, because no one wants to pass a cop
Learn about speed management [14]
Speed management is an approach to address speeding and speed related concerns to lower the likelihood of severe injuries or fatalities by reducing the frequency and severity of crashes. Additionally, effective speed management is critical for creating streets that support safe, comfortable, and convenient travel for everyone—whether you are in a car, on a bicycle, on foot, in a stroller, taking public transit, or using an assistive mobility device.
A few miles per hour difference can make a big impact on a person’s chance of survival. Higher speed crashes are more forceful than lower speed crashes, resulting in more damage to the driver, passengers, the vehicle, and people and property outside of the vehicle
Speed management improves safety for all roadway users. Whether you are walking or rolling to your parked car, driving down the street, strolling to the store, getting on the bus, or riding your bike to work, the biggest transportation threat you face is the speed of a passing vehicle
