Feature layer (hosted) containing Speed Limit & LRS Information.

Highway locations and various data: speed limits, surface type, access, etc, from the Colorado Department of Transportation (CDOT).

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

On November 7, 2014, New York City’s default speed limit was changed from 30 mph to 25 mph. Unless otherwise signed, all streets in New York City are governed by this 25 mph speed limit. Driving at or below 25 MPH decreases stopping distance, gives drivers and pedestrians more time to see each other and react, and improves drivers’ ability to avoid crashes. Pedestrians struck by vehicles traveling at 25 MPH are half as likely to die as those struck at 30 MPH. If crashes do occur, the severity of injuries is reduced a lower speeds. The information shown here was compiled by the New York City Department of Transportation for governmental purposes. The information is updated as soon as reasonably practicable. The public is advised that speed limits are subject to temporary or permanent change and that posted signage must be observed for compliance with laws and regulations.

This is a dynamic traffic map service with capabilities for visualizing traffic speeds relative to free-flow speeds as well as traffic incidents which can be visualized and identified. The traffic data is updated every five minutes. Traffic speeds are displayed as a percentage of free-flow speeds, which is frequently the speed limit or how fast cars tend to travel when unencumbered by other vehicles. The streets are color coded as follows:Green (fast): 85 - 100% of free flow speedsYellow (moderate): 65 - 85%Orange (slow); 45 - 65%Red (stop and go): 0 - 45%Esri's historical, live, and predictive traffic feeds come directly from HERE (www.HERE.com). HERE collects billions of GPS and cell phone probe records per month and, where available, uses sensor and toll-tag data to augment the probe data collected. An advanced algorithm compiles the data and computes accurate speeds. Historical traffic is based on the average of observed speeds over the past three years. The live and predictive traffic data is updated every five minutes through traffic feeds. The color coded traffic map layer can be used to represent relative traffic speeds; this is a common type of a map for online services and is used to provide context for routing, navigation and field operations. The traffic map layer contains two sublayers: Traffic and Live Traffic. The Traffic sublayer (shown by default) leverages historical, live and predictive traffic data; while the Live Traffic sublayer is calculated from just the live and predictive traffic data only. A color coded traffic map image can be requested for the current time and any time in the future. A map image for a future request might be used for planning purposes. The map layer also includes dynamic traffic incidents showing the location of accidents, construction, closures and other issues that could potentially impact the flow of traffic. Traffic incidents are commonly used to provide context for routing, navigation and field operations. Incidents are not features; they cannot be exported and stored for later use or additional analysis. The service works globally and can be used to visualize traffic speeds and incidents in many countries. Check the service coverage web map to determine availability in your area of interest. In the coverage map, the countries color coded in dark green support visualizing live traffic. The support for traffic incidents can be determined by identifying a country. For detailed information on this service, including a data coverage map, visit the directions and routing documentation and ArcGIS Help.

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.

Sign locations of posted speed limits in City of Aspen.

This layer identifies routes for bicyclists based on their relative experience. In 2015, the Stark County Regional Planning Commission (SCRPC) used available transportation data with input from the Stark County Bicycle Club to create a countywide map for bicyclists. SCRPC heavily weighted traffic volume, speed limit, and the number of lanes to determine which routes for more or less suitable for different levels of biking experience. Their formula also considered things like turn lanes and dedicated bike lanes. The end product was dubbed Ride Stark, and was used to create disputable paper maps, as well as an interactive online map that can be viewed here.For off-limit roadways for bicyclists in Stark County, see Ride Stark - Off-Limit Roadways.For on-road bike lanes in Stark County, see Ride Stark - Dedicated Bike Lanes.

Speed Zones (State and Local Roads)This layer shows the location of Speed Zones on all public access roads found in the Integrated Road Information System (IRIS) and includes temporal speed zones such as school zones. A school zone refers to an area on a street near a school or near a pedestrian crossing leading to a school that has a likely presence of younger pedestrians. School zones generally have a reduced speed limit during certain hours.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.

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 mapping of maximum speeds reached in centennial flood represents four classes of uniform velocity in intensity. This is an informative map, but projects submitted to a preliminary study must refer to it in addition to the water level.
