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.

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.Update FrequencyUpdates to the ArcGIS layer are triggered by changes in IRIS data and refreshed weekly.DisclaimerPlease note that you are accessing this data under a Creative Commons Attribution Licence, which includes a disclaimer of warranties and a limitation of liability.

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.

Posted speed limits in miles per hour (mph).

Automated Speed Enforcement (ASE), an automated system that uses a camera and a speed measurement device to enforce speed limits, is a speed enforcement tool that uses technology to help make roads safer for all users. Last updated in August 2024.

ASE is designed to work in tandem with other road safety measures, such as traffic calming, community safety zones, speed display boards, education initiatives, and police enforcement, to help improve safety for people of all ages by: ​ increasing speed compliancealtering driver behaviourincreasing public awareness about the critical need to slow down

An ASE system captures and records images only of vehicles travelling in excess of the posted speed limit in school zones and community safety zones, with tickets issued to the registered plate holder regardless of who was driving. This will result in a monetary fine, but no demerit points will be applied. The cameras are designed to follow traditional speed enforcement however the ASE threshold speed to trigger a fine is not being made public. This is standard practice across the province.

The fines for speeding in a Community Safety Zone are as follows: 1 to 19 km over the limit is $5.00 per kilometre plus costs 20 to 29 km over the limit is $7.50 per kilometre plus costs 30 to 49 km over the limit is $12.00 per kilometre plus costs ​

The City of Brampton was one of the first municipalities in Ontario to implement ASE, introducing its first notification sign on December 19, 2019.ASE will be deployed in Brampton in September 2020. You won’t see ASE everywhere – just in community safety zones​, and on roadways posted less than 80 km per hour, where it will be used to protect our most vulnerable populations and help them feel comfortable while walking, running, playing, cycling, and generally enjoying their communities. In an effort to build awareness, signage will also be installed at entry points in to the city to advise motorists that ASE is in effect and that speeding is not tolerated in the community.Council Approval of ASE Implementation (July 2020)ASE Camera Certificates of AccuracyASE Ontario

Speed limits on County-maintained roads in Sonoma County.

When people bicycle on roadways, they encounter varying levels of stress from traffic. A quiet residential street with a 25-mile-per-hour speed limit is considered a very low-stress environment for cyclists. But a six-lane suburban highway with a 40-mile-per-hour speed limit represents a high-stress environment for cyclists who must share the roadway with traffic. As a result, fewer people are likely to bicycle on the highway. Level of traffic stress (LTS) is an approach that quantifies the amount of discomfort that people feel when they bicycle close to traffic.
