Title:

MDOT SHA OOTS Sign Structures (Open Data) [Maryland]

Description:

The MDOT SHA OOTS Sign Structures dataset is an actively maintained database of sign structures in Maryland. The Maryland Department of Transportation, State Highway Administration, Office of Traffic Safety "OOTS" built and maintains the database with help from the MDOT SHA Office of Information Technology. Sign Structures in this open data database are only those set to an active* status. Structures information is further described by detailed attributes; the attributes definitions are listed below in the Data Dictionary section.Points of ContactData Owner: Faramarz "Faz" Sadeghi-Bajgiran for OOTSfbajgiran@mdot.maryland.govData Steward: Elliott Plack for OIT EISD:eplack.consultant@mdot.maryland.govTechnical Support: MDOT SHA OIT Enterprise Information Services - GIS Team:GIS@mdot.maryland.govData DictionarySign structure data are described by a number of attributes, including general ones, inspection details, and more.Str. ID: the Structure ID, a six-digit identifier. The first two digits represent the county. The last four digits are sequential.Status: the structure's status. Most structures are marked active. Structures with a "CFR" status are noted as "Call For Removal" and a slated to be removed or replaced in the noted time period.eDR Number: e-Design Number:Str. Type: the structure type, based on the design. Structures can either becantilevered (CN),overhead (OH), or acombination (CM).Owned by: the owner. Most are owned by MDOT SHA but certain special ones are owned by another state agency, a federal agency, e.g., NPS, or the tri-state compact, the Woodrow Wilson Bridge Commission.Maintained by: the agency responsible for maintaining/inspecting the structure. Usually, the same as owner but some structures have unique maintenance agreements.Acceptance Year: the year the structure was accepted into the state inventory and a good estimate of the age.End-of-Service: a future year in which the structure should be removed based on criteria.Removal Year: the year the structure was removed, in the case of inactive structures.Inspection ParametersStructures are repeatedly inspected as they are critical assets for navigation and would adversely affect the public if they were to fall. The inspections are closely monitored by OOTS. Inspections are categorized by In-Depth, Routine, or NDT (Non-Destructive Testing). Each inspection regime has the same attributes:Frequency: frequency in which inspections are due.Status: status of the current inspection cycle.CRS: Component Rating Score. A comprehensive, weighted rating score the considers each component of the sign.RAS: Risk Assessment Score: A criticality score based on criteria like traffic volume, speed limit, age, type, and proximity to critical infrastructure.CRS Date: The most recent CRS date.Due Date: The due date of the next inspection of the type.MOT: Maintenance of Traffic (MOT) procedures recommended for the particular structure.Other AttributesDMS ID: if there is a Dynamic Message Sign on the structure, the ID will be listed.# of AB's / Pole: Number of Anchor Bolts per Pole. The number varies by structure type.A reference to the numbering regime is here.AB Dia.: Anchor Bolt diameter in US inches.Span: the span is the length of the structure, in US feet. Span is the distance between posts or from the post to tip for cantilever structures.Clearance: the clearance underneath the structure in US feet.Cross Section Type: the cross-section type of the pole, typically round but there are other less common types.Contractor: the contractor that installed the structure, if known.Contract No: the contract under which the structure was installed.Manufacturer: the manufacture of the structure.Shop Drawings Exist: whether or not the shop drawings exist within MDOT SHA.B-2-P Connection: Base-to-Plate connection typeB-2-P Gusseted: Whether or not the Base-to-Plate is gusseted.TEDD Comments: comments made by the Traffic Engineering Design Division in OOTS. Contact OOTS with any questions.Creator/Editor: There are several automatic fields that track the username that create and last updated the asset, and at what time.Inactive Structures* Inactive structures, e.g., those that have been removed, are also captured in this database but that information is not available here. Contact OOTS if interested in inactive structures.
