A red light camera is a traffic camera that takes an image of a vehicle that goes through an intersection where the light is red. The system continuously monitors the traffic ...
Recent changes in ICT use globally have damaged the environment (in terms of waste and energy consumption etc.) but also have the potential to support environmental sustainability activities, [2] such as the targets set within the Millennium Development Goal (MDG) number 7 (MDG7) to "ensure environmental sustainability".
A traffic camera is a video camera which observes vehicular traffic on a road. Typically, traffic cameras are put along major roads such as highways, freeways, expressways and arterial roads, and are connected by optical fibers buried alongside or under the road, with electricity provided either by mains power in urban areas, by solar panels or other alternative power sources which provide ...
Security lighting to prevent intrusions may be counter-productive. Turning off lights halved the number of thefts and burglary in Övertorneå Sweden. [2] [3] A test in West Sussex UK showed that adding all-night lighting in some areas made people there feel safer, although crime rates increased 55% in those areas compared to control areas and to the county as a whole.
The radar triggers the camera to take several pictures when a nearby object exceeds this speed. Two pictures are required to determine vehicle speed using roadway survey markings. This can be reliable for traffic in city environments when multiple moving objects are within the field of view.
The health and environmental impact of transport is significant because transport burns most of the world's petroleum. This causes illness and deaths from air pollution , including nitrous oxides and particulates , and is a significant cause of climate change through emission of carbon dioxide .
Sodium vapor street light Closeup after dark. At end of life, high-pressure sodium (HPS) lamps exhibit a phenomenon known as cycling, caused by a loss of sodium in the arc. Sodium is a highly reactive element and is lost in a reaction with the aluminum oxide of the arc tube. The products are sodium oxide and aluminum: [32] 6 Na + Al 2 O 3 → 3 ...
Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.
