V85 refers to a principle on vehicle traffic law where the legal speed limit of a motorway is set such that 15% of drivers exceed the limit. [1] This is a common practice amongst many countries within the European Union, most notably France. [2]
Speed limits on road traffic, as used in most countries, set the legal maximum speed at which vehicles may travel on a given stretch of road. Speed limits are generally indicated on a traffic sign reflecting the maximum permitted speed, expressed as kilometres per hour (km/h) or miles per hour (mph) or both. Speed limits are commonly set by the legislative bodies of national or provincial governments and enforced by national or regional police and judicial authorities. Speed limits may also be variable, or in some places nonexistent, such as on most of the Autobahnen in Germany.
An intelligent transportation system (ITS) is an advanced application which aims to provide innovative services relating to different modes of transport and traffic management and enable users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks.
A pedestrian is a person traveling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or pavement, but this was not the case historically. Pedestrians may also be wheelchair users or other disabled people who use mobility aids.
Transport in Europe provides for the movement needs of over 700 million people and associated freight.
Traffic psychology is a discipline of psychology that studies the relationship between psychological processes and the behavior of road users. In general, traffic psychology aims to apply theoretical aspects of psychology in order to improve traffic mobility by helping to develop and apply crash countermeasures, as well as by guiding desired behaviors through education and the motivation of road users.
Sustainable transport refers to ways of transportation that are sustainable in terms of their social and environmental impacts. Components for evaluating sustainability include the particular vehicles used for road, water or air transport; the source of energy; and the infrastructure used to accommodate the transport. Transport operations and logistics as well as transit-oriented development are also involved in evaluation. Transportation sustainability is largely being measured by transportation system effectiveness and efficiency as well as the environmental and climate impacts of the system. Transport systems have significant impacts on the environment, accounting for between 20% and 25% of world energy consumption and carbon dioxide emissions. The majority of the emissions, almost 97%, came from direct burning of fossil fuels. In 2019, about 95% of the fuel came from fossil sources. The main source of greenhouse gas emissions in the European Union is transportation. In 2019 it contributes to about 31% of global emissions and 24% of emissions in the EU. In addition, up to the COVID-19 pandemic, emissions have only increased in this one sector. Greenhouse gas emissions from transport are increasing at a faster rate than any other energy using sector. Road transport is also a major contributor to local air pollution and smog.
The Erasmus Programme is a European Union (EU) student exchange programme established in 1987. Erasmus+, or Erasmus Plus, is the new programme combining all the EU's current schemes for education, training, youth and sport, which was started in January 2014.
An arterial road or arterial thoroughfare is a high-capacity urban road that sits below freeways/motorways on the road hierarchy in terms of traffic flow and speed. The primary function of an arterial road is to deliver traffic from collector roads to freeways or expressways, and between urban centres at the highest level of service possible. Therefore, many arteries are limited-access roads, or feature restrictions on private access. Because of their relatively high accessibility, many major roads face large amounts of land use and urban development, making them significant urban places.
The RAC Foundation is a registered charity.
The International Association of Public Transport is a non-profit member-led organisation for public transport authorities, networks and operators, policy decision-makers, scientific institutes and the public transport supply and service industry, that works to advance sustainable urban mobility.
A motorized scooter is a stand-up scooter powered by either a small internal combustion engine or electric hub motor in its front and/or rear wheel. Classified as a form of micro-mobility, they are generally designed with a large center deck on which the rider stands. The first motorized scooter was manufactured by Autoped in 1915.
Intelligent speed assistance (ISA), or intelligent speed adaptation, also known as alerting, and intelligent authority, is any system that ensures that vehicle speed does not exceed a safe or legally enforced speed. In case of potential speeding, the driver can be alerted or the speed reduced automatically.
Vision Zero is a multi-national road traffic safety project that aims to achieve a roadway system with no fatalities or serious injuries involving road traffic. It started in Sweden and was approved by their parliament in October 1997. A core principle of the vision is that "Life and health can never be exchanged for other benefits within the society" rather than the more conventional comparison between costs and benefits, where a monetary value is placed on life and health, and then that value is used to decide how much money to spend on a road network towards the benefit of decreasing risk.
Active mobility, soft mobility, active travel, active transport or active transportation is the transport of people or goods, through non-motorized means, based around human physical activity. The best-known forms of active mobility are walking and cycling, though other modes include running, rowing, skateboarding, kick scooters and roller skates. Due to its prevalence, cycling is sometimes considered separately from the other forms of active mobility.
Certain urban multiple-lane roads may have higher speed limits posted.
30 km/h zones and the similar 20 mph zones are forms of speed management used across areas of urban roads in some jurisdictions. The nominal maximum speed limits in these zones are 30 kilometres per hour (19 mph) and 20 miles per hour (32 km/h) respectively. Although these zones do have the nominal speed limit posted, speeds are generally ensured by the use of traffic calming measures, though limits with signs and lines only are increasingly used in the UK.
Transport Research Arena (TRA) is a conference on transport and mobility in Europe. It was initiated in 2006 and takes place every two years in a different European city. TRA is co-organised by the European Commission and supported by the European Technology Platforms ERTRAC, ERRAC, WATERBORNE as well as CEDR and ALICE, ETRA and ECTP.
A personal transporter is any of a class of compact, mostly recent, motorised micromobility vehicle for transporting an individual at speeds that do not normally exceed 25 km/h (16 mph). They include electric skateboards, kick scooters, self-balancing unicycles and Segways, as well as gasoline-fueled motorised scooters or skateboards, typically using two-stroke engines of less than 49 cc (3.0 cu in) displacement. Many newer versions use recent advances in vehicle battery and motor-control technologies. They are growing in popularity, and legislators are in the process of determining how these devices should be classified, regulated and accommodated during a period of rapid innovation.
A scooter-sharing system is a shared transport service in which electric motorized scooters are made available to use for short-term rentals. E-scooters are typically "dockless", meaning that they do not have a fixed home location and are dropped off and picked up from certain locations in the service area.
Micromobility refers to a range of small, lightweight vehicles, driven by users personally. Micromobility devices include bicycles, e-bikes, electric scooters, electric skateboards, shared bicycle fleets, and electric pedal assisted (pedelec) bicycles.
