GraphHopper Community
GraphHopper is an open-source routing library and server written in Java and provides a web interface called GraphHopper Maps as well as a routing API over HTTP. It runs on the server, desktop, Android, iOS or Raspberry Pi. By default OpenStreetMap data for the road network and elevation data from the Shuttle Radar Topography Mission is used. GraphHopper can be configured to use different algorithms such as Dijkstra, A* and its bidirectional versions. To make routing fast enough for long paths (continental size) and avoid heuristical approaches GraphHopper uses contraction hierarchies by default. In the Java Magazine from Oracle, the author, Peter Karich, describes the techniques necessary to make the system memory efficient and fast. Furthermore, GraphHopper is built on a large test suite including unit, integration and load tests. Version 1.0 was released in May 2020. The Apache License allows everyone to customize and integrate GraphHopper in free or commercial products, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scotland Yard (board Game)
''Scotland Yard'' is a board game in which a team of players controlling different detectives cooperate to track down a player controlling a criminal as they move around a board representing the streets of London. It was first published in 1983. It is named after Scotland Yard - the headquarters of London's Metropolitan Police Service in real-life. ''Scotland Yard'' is an asymmetric board game, during which the detective players cooperatively solve a variant of the pursuit–evasion problem. The game is published by Ravensburger in most of Europe and Canada and by Milton Bradley in the United States. It received the ''Spiel des Jahres'' (Game of the Year) award in 1983 - the same year that it was published. Gameplay One player controls 'Mr. X': a criminal whose location is only revealed periodically throughout gameplay. The other players each control a detective, all of which are always present on the board. All players start with a number of tokens ("tickets") which each allo ...

Virtual Reality
Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isochrone Map
An isochrone map in geography and urban planning is a map that depicts the area accessible from a point within a certain time threshold. An isochrone (iso = equal, chrone = time) is defined as "a line drawn on a map connecting points at which something occurs or arrives at the same time". In hydrology and transportation planning isochrone maps are commonly used to depict areas of equal travel time. The term is also used in cardiology as a tool to visually detect abnormalities using body surface distribution. History Early examples of Isochrone maps include the Galton's ''Isochronic Postal Charts'' and ''Isochronic Passage Charts'' of 1881 and 1882, Bartholomew's ''Isochronic Distance Map and Chart'' first published 1889 and Albrecht Penck's ''Isochronenkarte'' first published 1887. Where as Galton and the Bartholomews published maps depicting the days or weeks it took to travel long distances, Albrecht further developed the idea to not only depict long distances and world trav ...

Traffic Simulation
Traffic simulation or the simulation of transportation systems is the mathematical modeling of transportation systems (e.g., freeway junctions, arterial routes, roundabouts, downtown grid systems, etc.) through the application of computer software to better help plan, design, and operate transportation systems. Simulation of transportation systems started over forty years ago, and is an important area of discipline in traffic engineering and transportation planning today. Various national and local transportation agencies, academic institutions and consulting firms use simulation to aid in their management of transportation networks. Simulation in transportation is important because it can study models too complicated for analytical or numerical treatment, can be used for experimental studies, can study detailed relations that might be lost in analytical or numerical treatment and can produce attractive visual demonstrations of present and future scenarios. To understand simulatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Planning
Urban planning, also known as town planning, city planning, regional planning, or rural planning, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks and their accessibility. Traditionally, urban planning followed a top-down approach in master planning the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental bottom-lines that focus on planning as a tool to improve the health and well-being of people while maintaining sustainability standards. Sustainable development was added as one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Map Matching
Map matching is the problem of how to match recorded geographic coordinates to a logical model of the real world, typically using some form of Geographic Information System. The most common approach is to take recorded, serial location points (e.g. from GPS) and relate them to edges in an existing street graph (network), usually in a sorted list representing the travel of a user or vehicle. Matching observations to a logical model in this way has applications in satellites navigation, GPS tracking of freight, and transportation engineering. Map matching algorithms can be divided in real-time and offline algorithms. Real-time algorithms associate the position during the recording process to the road network. Offline algorithms are used after the data is recorded and are then matched to the road network. Real-time applications can only calculate based upon the points prior to a given time (as opposed to those of a whole journey), but are intended to be used in 'live' environments. T ...
