Description: The Off-System are routes on AHTD's Linear Referencing System (LRS) that for the most part are not part of the State Highway System but qualify for Federal Aid because they are on the Functional Class System. The AHTD identifies these routes on the LRS because they are required to report condition, events, assets, etc. on them. The majority of the routes are county routes and city streets. However, we also put Frontage Roads, Ramps, Institutional Drives (College Campus Roads, Hospital Roads, Airport Roads and State Park Roads) on the Off-System layer.

Description: This data set contains Functional Classification roads for the State of Arkansas per the Arkansas Highway and Transportation Department (AHTD). This file should only be used as a graphical representation and for general reporting. Field verification and source contact should always occur prior to financial planning taking place. Functional classification is the process by which streets and highways are grouped into classes, or systems, according to the character of service they are intended to provide. Basic to this process is the recognition that individual roads and streets do not serve travel independently in any major way. Rather, most travel involves movement through a network of roads. It becomes necessary then to determine how this travel can be channelized within the network in a logical and efficient manner. Functional classification defines the nature of this channelization process by defining the part that any particular road or street should play in serving the flow of trips through a highway network.

Description: A road is a motor vehicle travel way over 50 inches wide, unless classified and managed as a trail. A road may be classified or unclassified. Classified roads are roads within National Forest System lands planned and managed for motor vehicle access including State roads, county roads, private roads, permitted roads, and Forest Service roads. Unclassified roads are roads not intended to be a part of nor managed as a part of the forest transportation system, such as temporary roads, and unplanned, unengineered, unauthorized off-road vehicle tracks and abandoned travel ways. Route measurements and route directions must correspond to those stored in the Infra Oracle table RTE_BASICS.
Description: The Ozark - St. Francis National Forests have nine scenic byways, approximately 222 miles. Scenic byway corridors are managed to offer visitors the opportunity to enjoy viewing outstanding natural and cultural landscapes along a well-maintained road. These areas may contain recreational and interpretive trails. These visible area during dormant seasons defines the byway corridors, unless other criteria are established in the specific scenic byway management plan. These areas privide exceptional opportunities for motorized recreation, especially scenic driving.
Description: A trail is a linear feature constructed for the purpose of allowing the free movement of people, stock, or Off Highway Vehicles (OHV). Route measurements and route directions must correspond to those stored in the Infra Oracle table RTE_BASICS.
Description: This dataset is a subset of the dataset titled ALL CULTRAL POINTS, created by the Arkansas Highway and Transportation Department. Combinations of all of the cultural features are plotted when updating county and city maps in the Mapping Section at the Arkansas State Highway and Transportation Department

Description: The 2005 First Edition TIGER/Line files are an extract of selected geographic and cartographic information from the Census TIGER database. The geographic coverage for a single TIGER/Line file is a county or statistical equivalent entity, with the coverage area based on the latest available governmental unit boundaries. The Census TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each county-based TIGER/Line file is designed to stand alone as an independent data set or the files can be combined to cover the whole Nation. The 2005 First Edition TIGER/Line files consist of line segments representing physical features and governmental and statistical boundaries. The files contain information distributed over a series of record types for the spatial objects of a county. There are 19 record types, including the basic data record, the shape coordinate points, and geographic codes that can be used with appropriate software to prepare maps. Other geographic information contained in the files includes attributes such as feature identifiers/census feature class codes (CFCC) used to differentiate feature types, address ranges and ZIP Codes, codes for legal and statistical entities, latitude/longitude coordinates of linear and point features, landmark point features, area landmarks, and area boundaries.

Description: Data available online through the Arkansas Spatial Data Infrastructure (ASDI) at http://gis.arkansas.gov. The subject file represents the Arkansas portion of a geographic data set of runways in the United States and US territories containing information on the physical characteristics of the runways. The 8550 runways in the data set are supposed to include all of the runways associated with the 6734 airports in the companion airport data set Airports, 1998 (BTS). Data were obtained from the Federal Aviation Administration's (FAA) National Flight Data Center (NFDC) 5010 landing facilities data (January 1999). Landing facilities in this database consist of those identified in the NFDC 5010 database to be either publicly owned, or privately owned but open to the public, or owned by the U.S. military. The following landing facilities have been excluded: private landing facilities not open to the public, glider ports and ultra light landing facilities, as well as landing facilities that do not have a current LOCID assigned to them. Horizontal positional accuracy is based on coordinate data provided in the NFDC 5010 database. These coordinate data identify the approximate location of the Airport Reference Point (ARP) as reported by the landing facility on the NFDC 5010 form. According to NFDC guidelines, the location of the ARP should be reported to a horizontal accuracy of one arc second of latitude and longitude. However, the accuracy of these reported coordinates are not verified by FAA. The scale is unknown.
Description: The Vehicle Percent Data consists of the Vehicle Percent calculations taken for specific segment on the State Highways of Arkansas.

Description: ARKANSAS STATE HIGHWAY AND TRANSPORTATION DEPARTMENT Process for Establishing a Weight Restriction on A Non-weight Restricted HighwayIt is beneficial to the motorists of Arkansas that full, unrestricted access be provided on all highways when possible. However, it is the responsibility of the Department to ensure that the highways are maintained in a condition suitable for use by the traveling public. In order to maintain some sections of highways in a suitable condition, it may be necessary at times to limit the amount of weight that can be carried by a single load on those sections.The following is the process by which sections of highways that are experiencing significant deterioration can be weight restricted to preserve their conditions.The initial evaluation and continual monitoring of all highways is the responsibility of the appropriate District Engineer and staff.Distress that can be attributed to loadings in excess of those for which the pavement was designed or is the result of seasonal or unusual conditions that have changed the characteristics of the pavement or supporting base may be cause for a pavement evaluation. At the first sign of significant distress in a highway pavement for which there are no near-term improvements, the District Engineer will evaluate the route and report the evaluation to the State Maintenance Engineer. After consultation, the District Engineer or the State Maintenance Engineer may request a roadway strength analysis from the Planning and Research Division. Pavement and base information from the Materials Division will be combined with data from the Falling Weight Deflectometer (FWD) to assess pavement strengths. The results of the pavement strength analysis will be reported to the State Maintenance Engineer and the District Engineer.If the pavement strength analysis indicates a short remaining pavement life due to the increased loading or seasonal conditions, the District Engineer and State Maintenance Engineer will consult to determine whether the posting of a weight restriction is recommended. The State Maintenance Engineer will forward the strength analysis and supporting data to the Assistant Chief Engineer-Operations with a recommendation for the posting of a weight restriction of the highway. The recommendation will include the specific weight restriction that the State Maintenance Engineer and the District Engineer believe to be appropriate.The Assistant Chief Engineer-Operations will coordinate the weight restriction recommendations with a committee composed of the Assistant to the Director and the Assistant Chief Engineers for Planning and for Design. The Assistant Chief Engineer-Operations will forward a final recommendation to the Deputy Director and Chief Engineer for approval.Upon the Deputy Director and Chief Engineer’s approval of the posting of a weight restriction, the District Engineer will make a public notification to the local media 10 days in advance of the official posting. In addition, the District Engineer will make necessary notifications within the Department and arrange for appropriate signing of the route for enforcement purposes.This process should be considered for preventing failure of the pavement after all reasonable standard maintenance operations are used to maintain and strengthen a pavement.
