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).

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.

Geospatial data about City of Dallas, Texas Speed Limits. Export to CAD, GIS, PDF, CSV and access via API.

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.

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 speeds Yellow (moderate): 65 - 85% Orange (slow); 45 - 65% Red (stop and go): 0 - 45%Esri's historical, live, and predictive traffic feeds come directly from TomTom (www.tomtom.com). Historical traffic is based on the average of observed speeds over the past year. 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.

The City collects speed data from a number of locations across the entire city. The devices used to collect this speed data are referred to as speed survey equipment. To read more about the devices used, please follow this link:

http://mhcorbin.com/Products/Product-Detail/Article/43/NC350-BlueStar-Traffic-Analyzer

In order to align data that is collected by the speed survey equipment and the Speed Check Signs (formerly called 'Driver Feedback Signs'), the following has been done:

• Data has been aggregated into in 15 minute intervals
• Vehicle speeds are captured/reported in speed intervals (bins)
• Speed range/interval for the bins are aligned with the program settings for Speed Check Sign units that collect data from roadways with the same speed limit
• The bins go from Bin 1 to Bin 10. Bin 1 can also be referred to a LO BIN and Bin 10 can also be referred to as HIGH BIN.

Things to note:

Data represented in this dataset was collected in 2017 Data represented in this dataset is not to be used as or confused with traffic counters, due to the aggregating factor and the alignment of speed ranges to that of Speed Check Sign units. Speed survey equipment has a minimum detectable speed of approximately 8 km/hr (which does not align with Speed Check Sign units which has a 6 km/hr minimum detectable speed) Speed survey equipment has a maximum detectable speed of approximately 193 km/hr (which also does not align with Speed Check Sign units which has a 225 km/hr maximum detectable speed) Speed survey equipment is not programmable (i.e. there are no parameter settings based on the speed limit or a timed schedule as to how to record the data)

The map layers in this service provide color-coded maps of the traffic conditions you can expect for the present time (the default). The map shows present traffic as a blend of live and typical information. Live speeds are used wherever available and are established from real-time sensor readings. Typical speeds come from a record of average speeds, which are collected over several weeks within the last year or so. Layers also show current incident locations where available. By changing the map time, the service can also provide past and future conditions. Live readings from sensors are saved for 12 hours, so setting the map time back within 12 hours allows you to see a actual recorded traffic speeds, supplemented with typical averages by default. You can choose to turn off the average speeds and see only the recorded live traffic speeds for any time within the 12-hour window. Predictive traffic conditions are shown for any time in the future.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.

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.Data sourceEsri’s typical speed records and 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. The real-time and predictive traffic data is updated every five minutes through traffic feeds.Data coverageThe 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. Look at the coverage map to learn whether a country currently supports traffic.
