GTFS Realtime (also known as GTFS-rt) is an extension to GTFS, in which public transport agencies share real-time vehicle locations, arrival time predictions, and alerts such as detours and cancellations via Protocol Buffers web server. [1] Realtime location data is created continuously by an agency from automatic vehicle location (AVL) systems ...
The APIs provide functionality like analytics, machine learning as a service (the Prediction API) or access to user data (when permission to read the data is given). Another important example is an embedded Google map on a website, which can be achieved using the Static Maps API, [1] Places API [2] or Google Earth API. [3]
Isochrone maps have been used in transportation planning since at least 1887. [21] [22] Isochrone maps in the context of transport planning are essentially maps of accessibility where travel time is used as the cost metric. Isochrone maps can be created for different modes of transportation, [23] e.g. foot, bicycle, motor vehicle. Put simply ...
Traffic cam. Traffic reporting is the near real-time distribution of information about road conditions such as traffic congestion, detours, and traffic collisions. The reports help drivers anticipate and avoid traffic problems. Traffic reports, especially in cities, may also report on major delays to mass transit that does not necessarily ...
GTFS or the General Transit Feed Specification defines a common data format for public transportation schedules and associated geographic information. [1] GTFS contains only static or scheduled information about public transport services, and is sometimes known as GTFS Static or GTFS Schedule to distinguish it from the GTFS Realtime extension, which defines how information on the realtime ...
This can include static and moving data, maps, satellite imagery, crowd-sourced data, full motion video, weather data and terrain elevation in many different geodetic references and map projections. Geo-fencing, line-of-sight calculations, geo-triggered events, dynamic and complex route calculations and automated anomaly detection are just a ...
It also gives us real-time updates about traffic and road conditions which can lead to safer travels. Although not a common use, web mapping can be used to learn more about culture and history. You can explore historical maps, cultural landmarks, natural features, parks, trails, report issues, natural hazards, pollution, and much more. [34]
A traffic congestion map is a graphical, realtime or near-realtime representation of traffic flow for some particular area. [1] Data is typically collected via anonymous GPS datapoints and loop sensors embedded in the roadways, then processed by computer at a central facility and distributed as a map view to users.
