Speed limit information for most of Queensland's roads. Includes state and locally controlled roads. Point-in-time data as per date of collection in dataset.

This map provides information on speed limits that are posted on state-maintained roadways in Virginia. Cities and towns set their own speed limits and these are not available to show on the map. Zoom in on the map to display the speed limits. Speed limits exist for all roads however; where this information is not available for mapping, they are not displayed. Most roads where speed limits are not shown are either rural, secondary roads (routes numbered 600 or greater) where a statutory 55 mph speed limit typically applies, or subdivision streets where a statutory 25 mph speed limit usually applies. These statutory speed limits are often are not posted on these roads. Click on any roadway to display the speed limit information.

This map contains speed limits for all roads in the National Road Database (NWB).

Description from Rijkswaterstaat: "Since 2022, the features are Trees, Entrances, Bowl Boundaries, Parking Points , Parking spaces, Traffic center, Traffic types, Road width, Road categorization and Road narrowings added as a csv file to the database."

"The possible speeds that can be entered are 5, 15, 20, 30 40, 50, 60, 70, 80, 90, 100, 120, 130 km per hour, N/A and unknown. The speeds only apply to roads that are open to car traffic. On cycle paths , footpaths and other roads that are not open to car traffic, the speed is unknown. This also applies to the ferry connections. The file provides variable maximum speeds with a start time and an end time. These mainly apply to motorways. Outside this period with the indicated start time and end time, an alternative speed applies. So, for example, between 6:00 AM and 7:00 PM the speed limit is 100 km per hour and outside of that the maximum speed is 120 km per hour."

Traffic decisions, via the Knowledge and Operation Center for Official Government Publications (KOOP), are used to detect and process changes in speed limits.

Disclaimer:

A number of roads are currently still listed as "unknown" while the speed limit does not actually apply here (pedestrian paths and cycle paths, for example).

The road characteristics database (WKD) for speeds contains speed limits for all roads in the NWB. At the beginning of 2017, WKD was filled for the entire Netherlands with data supplied by municipalities. From that moment on, the new traffic decisions have been used via the Knowledge and Operation Center for Official Government Publications (KOOP) to detect and process changes in speed limits. The NWB changes faster than the speed limits are supplied by the road authorities or placed in COOP. Algorithms are used to supplement the speed where necessary on short intermediate road sections. As a result, the speed limit is unknown for a few percent. Since 2022, the features Trees, Entrances, Bowl Boundaries, Parking Points, Parking Spaces, Traffic Center, Traffic Types, Road Width, Road Categorization and Road Narrowings have been added to the database as a CSV file. NB: In residential areas where a maximum speed of 30 km per hour applies, or in a residential area, this leads to major deviations from reality. The number of rural roads with a 60 km limit has also increased significantly since 2017. The possible speeds that can be entered are 5, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 120, 130 km per hour and unknown. The speeds only apply to roads that are open to car traffic. On cycle paths, footpaths and other roads that are not open to car traffic, the speed is entered as unknown. This also applies to the ferry connections. The file provides variable maximum speeds with a start time and an end time. These apply in particular to motorways. Outside this period with the indicated start time and end time, an alternative speed applies. So, for example, between 6:00 AM and 7:00 PM the speed limit is 100 km per hour and outside of that time the maximum speed is 120 km per hour. The road characteristics database for speeds also contains the recommended speed limits that apply to a specific road section or part thereof.

It contains the full detail layer of the extents for certified speed limit records from 26 May 2022 onwards, and their associated attribute data.Previously, 68 different road controlling authorities (RCAs) published this information in multiple formats.You can use the data for:time-based analysisanalysis against other datasets, for example addressesbuilding additional datasets.The data is extracted from the NSLR on a nightly basis.New emergency speed limits are updated in this dataset shortly after being created in the NSLR.Note: speed limit record geometries (shapefiles) will overlap. This will be in addition to overpasses, underpasses, intersections, bus lanes, opposing speed differences and multiple speeds in the same direction. For example, if you have an overpass one speed limit will be given for the top level (bridge) and the second overlapping geometry for the bottom level (I.e. road under bridge).Permanent speed limit: A speed limit that’s in force except when a seasonal, variable, temporary - emergency or other temporary speed limit is in force.Variable speed limit: A speed limit that changes under certain conditions (excluding seasonal), for example due to the presence of a school where the speed limit is different at certain times of the day depending on the school activity.Seasonal speed limit: A speed limit that applies on a seasonal basis, for example during a holiday period. Seasonal speed limits can be one-off or recurring.Emergency speed limit: A speed limit put in place due to an emergency, for example an earthquake, tsunami or epidemic.The principles for how the speed limits interact with each other are as follows.Permanent and variable speed limits cannot overlap one another.A seasonal speed limit can overlap permanent and variable speed limits.A seasonal speed limit can overlap another seasonal speed limit, as long as the speed limit is not active at the same time as the record it is overlapping (i.e.one seasonal speed limit cannot overlap another seasonal speed limit).An emergency record can overlap a seasonal record but cannot overlap another emergency record.Temporary speed limits, other than emergency, are not included in this dataset.Members of the public can search for speed limits on New Zealand roads, obtain details of specific speed limits and obtain certified copies of speed limits through the NSLR web application. NSLR web browser applicationData reuse caveatsAs per license.Data quality statementRCAs signed off that the data in the NSLR is a true and accurate reflection of their bylaw. There is a high level of confidence in data quality, and we welcome user feedback.Data quality caveatsThe data has been migrated as provided by respective RCAs according to their current bylaw. There are errors as a result of having to migrate the legal speed limits as per the bylaw rather than what is signed on the ground. Many (but not all) of these were identified and RCAs can apply for Director’s approval to fix them.There is two known issues with the display of this data in Open Data, these are display issues within the Open Data application and do not impact the data when downloaded or used via API:Where there is no date 'December 31, 1969' is shown.Where there is no text 'null' is shown

Statewide Road Network including sealed and unsealed roads. The dataset represents navigable roads, including public and private access roads and tracks. A separate data layer stores 'unformed' DCDB centrelines which do not represent navigable roads. A limited number of associated features are stored separately as point features. Automatically updated when changes occur.

Speed Signs is a spatial dataset (point) that shows the location of every Speed Limit sign across Victoria including advisory 'Speed Limit Ahead' signs. The data includes attributes such as Road Name, Sign Size, Type, Speed Value, Bearing and Direction. Variable speed signs display the alternative speed limit during the times that limit is active. This is captured in the variable time and day fields in the dataset. A standard ('static') speed sign with the prevailing speed limit is provided at the end of the zone which serves to end the variable zone, or act as a reminder sign for times when the variable speed limit isn't active. Data Quality Whilst every effort has been made to ensure this information is up-to-date, there may be instances where signs are not yet recorded in this system.

The source data is in XML web service and been processed and converted into Esri File Geodatabase format and then uploaded to Esri’s ArcGIS Online platform for sharing and reference purpose. The objectives are to facilitate our Hong Kong ArcGIS Online users to use the data in a spatial ready format and save their data conversion effort.

This datasets presents Legal Speed Limits on state and local roads. The speed limit is the maximum speed limit allowed under the provisions of the State Traffic Act and Regulations. Road speed limits are used to regulate the speed of road vehicles. Speed limits may define maximum (which may be variable), minimum or no speed limit and are normally indicated using a traffic sign. Speed limits are set by the Commissioner of Main Roads Western Australia (Regulation 297 of the Road Traffic Code 2000) and enforced by national or regional police and/or judicial bodies. This layer shows the location of legal speed limits on all public access roads found in the Integrated Road Information System (IRIS) and is provided for information only. This data presents the speed limits of roads in Western Australia as of August 2018. For more information please visit the MRWA Open Data Portal.

This dataset contains the current estimated speed for about 1250 segments covering 300 miles of arterial roads. For a more detailed description, go to: http://bit.ly/Q9AZAD.

The Chicago Traffic Tracker estimates traffic congestion on Chicago’s arterial streets (nonfreeway streets) in real-time by continuously monitoring and analyzing GPS traces received from Chicago Transit Authority (CTA) buses. Two types of congestion estimates are produced every ten minutes: 1) by Traffic Segments and 2) by Traffic Regions or Zones. Congestion estimate by traffic segments gives the observed speed typically for one-half mile of a street in one direction of traffic.

Traffic Segment level congestion is available for about 300 miles of principal arterials. Congestion by Traffic Region gives the average traffic condition for all arterial street segments within a region. A traffic region is comprised of two or three community areas with comparable traffic patterns. 29 regions are created to cover the entire city (except O’Hare airport area). This dataset contains the current estimated speed for about 1250 segments covering 300 miles of arterial roads. There is much volatility in traffic segment speed. However, the congestion estimates for the traffic regions remain consistent for relatively longer period. Most volatility in arterial speed comes from the very nature of the arterials themselves. Due to a myriad of factors, including but not limited to frequent intersections, traffic signals, transit movements, availability of alternative routes, crashes, short length of the segments, etc. speed on individual arterial segments can fluctuate from heavily congested to no congestion and back in a few minutes. The segment speed and traffic region congestion estimates together may give a better understanding of the actual traffic conditions.
