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.

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 data set is a linear representation of the extents and attribution associated with speed limit as derived from speed zone records as originally created by the Traffic Engineering Division (TED) of VDOT. This data layer was created for Speed Zone application of Roadway Network System by extracting the zone location information for each feature from the speed zone database and then applying this location description to the linear referencing system built for the Virginia roadway network, and then associating the zone business data to the spatially located feature. Over time new speed zones are created that may overlap - supersede an existing zone. This layer uses business rules to calculate the speed limit. A conventional zone and a variable limit may exist at a single selected location. This data set is maintained by RNS application. There are two types of SPZ records first are for "Statutory" zones where signs are erected to mark roads on which the statutory speed limits apply. The second type of zone is "Resolution" in which the VDOT Commissioner approves changes in speed limits based on recommendations from TED following traffic studies at the proposed location. In these cases the speed limit may be set to any recommended value, in 5 mph increments, and with differing speed limits for trucks versus other vehicles, different speed limits based on time of day, etc.

The data on provincial highway speed limit signs (Category 5 signs) is exported from the Highway Basic Data Database of the Highway Bureau. In addition to CSV format, the bureau also provides the facility information in KMZ format for reference.

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.

Speed Limits

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

Description from Rijkswaterstaat: "Since 2022, the characteristics Trees, Entrances, Comb Borders, Parking Points, Parking Boxes, Traffic Center, Traffic Types, Road Width, Road Categorization and Road Narrowings have been added to the database as a csv file."

"The possible speeds that can be entered are 5, 15, 20, 30 40, 50, 60, 70, 80, 90, 100, 120, 130 km/h, 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 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 and 19:00, 100 km per hour applies and beyond that, the maximum speed is 120 km per hour.

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

Disclaimer:

There are still a number of roads on "unknown" while here actually the maximum speed does not apply (footpaths and cycle paths for example).

This dataset comprises road centerlines for all roads in San Diego County. Road centerline information is collected from recorded documents (subdivision and parcel maps) and information provided by local jurisidictions (Cities in San Diego County, County of San Diego). Road names and address ranges are as designated by the official address coordinator for each jurisidcition. Jurisdictional information is created from spatial overlays with other data layers (e.g. Jurisdiction, Census Tract).The layer contains both public and private roads. Not all roads are shown on official, recorded documents. Centerlines may be included for dedicated public roads even if they have not been constructed. Public road names are the official names as maintained by the addressing authority for the jurisdiction in which the road is located. Official road names may not match the common or local name used to identify the road (e.g. State Route 94 is the official name of certain road segments commonly referred to as Campo Road).Private roads are either named or unnamed. Named private roads are as shown on official recorded documents or as directed by the addressing authority for the jurisdiction in which the road is located. Unnamed private roads are included where requested by the local jurisidiction or by SanGIS JPA members (primarily emergency response dispatch agencies). Roads are comprised of road segments that are individually identified by a unique, and persistent, ID (ROADSEGID). Roads segments are terminated where they intersect with each other, at jurisdictional boundaries (i.e. city limits), certain census tract and law beat boundaries, at locations where road names change, and at other locations as required by SanGIS JPA members. Each road segment terminates at an intersection point that can be found in the ROADS_INTERSECTION layer.Road centerlines do not necessarily follow the centerline of dedicated rights-of-way (ROW). Centerlines are adjusted as needed to fit the actual, constructed roadway. However, many road centerline segments are created intially based on record documents prior to construction and may not have been updated to meet as-built locations. Please notify SanGIS if the actual location differs from that shown. See the SanGIS website for contact information and reporting problems (http://www.sangis.org/contact/problem.html).Note, the road speeds in this layer are based on road segment class and were published as part of an agreement between San Diego Fire-Rescue, the San Diego County Sheriff's Department, and SanGIS. The average speed is based on heavy fire vehicles and may not represent the posted speed limit.

SpeedMap is a project with the aim of producing a national speed limit database for the UK and Republic of Ireland which can be used with any digital map. Ten years ago we recognised the need for an accurate map to support innovation in road safety – without being tied to a costly proprietary mapping solution. Our data is sourced from a multitude of datasets and boasts 100% coverage of the UK and RoI road network with industry-leading accuracy >99%. Since supplying the first version to a telematics startup in 2012, SpeedMap has become the number one choice for companies who need speed limit data. Our dataset is used by global mapping providers, delivery companies, utility providers, insurance companies, as well as those providing in-vehicle systems. We make our data accessible, reliable and exploitable for your commercial needs, as well as putting the data in the hands of those responsible for making our roads safer.

Thanks to OS MasterMap Highways Network with Speed Data, you can also access road speed information through our product. It’s an additional dataset to help you plan logistics and monitor our roads more effectively.

Perhaps you're looking for more data about Great Britain's roads? Or maybe you're studying drive times or comparing vehicle types along routes or the impact of a new development? This could be the product for you.

We have enhanced our Highways Network family of products with these three speed data additions. Each product is supplied with an additional data file which will be either Average Speed, Speed Limits or a combination of both.

This is an extract from the State Highway Log that shows legal speed limits along State Routes. State Route identifiers and locations based on State Route Mileposts and Accumulated Route Mileage are also included for geographic reference and for use with the Washington State Department of Transportation's 24k and 500k Linear Referencing Systems. Please direct questions about this dataset to: TransportationGISDataSteward@wsdot.wa.gov.

Traffic Speed Zones. Maximum speed limits on streets.Speed Zone data are maintained by the Transportation department and automatically copied to the Open Data Portal. The "Last Updated" date shown on our Open Data Portal refers to the last time the data schema was modified in the portal, or any changes were made to this description. We update our data through automated scripts which does not trigger the "last updated" date to change.Note: Attributes represent each field in a dataset, and some fields will contain information such as ID numbers. As a result some visualizations on the tabs on our Open Data page will not be relevant.

Here are a few use cases for this project:

1. Traffic Management Applications: Traffic authorities can use the "Speed Limitation" model to monitor highways and city roads for compliance with speed limits. If a vehicle is detected to be exceeding the speed limit, automatic notifications can be sent either to the vehicle's dashboard (in smart cars) or directly to traffic police.

2. Navigation And Map Services: Integrate it into map services like Google Maps, Waze, or in-car navigation systems to alert drivers about the speed limits in real-time, improving road safety and preventing speeding tickets.

3. Autonomous Vehicle Systems: Utilize this model as part of the guidance and regulation systems in self-driving cars. The cars will constantly scan for these signs to adapt their driving speed in real-time, ensuring they adhere to road regulations.

4. Traffic-Related Intelligent Tutoring Systems: Educators can leverage it in driving schools or online driver education programs, teaching new drivers to identify and understand the diverse speed-related traffic signs and abide by them.

5. Research and Studies: Researchers in traffic engineering and road safety can use this model to investigate the impact of different speed limits on traffic flow and accident rates, strengthening their understanding of real-world traffic conditions and proposing efficient road management strategies.
