{ "currentVersion": 11.3, "cimVersion": "3.3.0", "id": 0, "name": "2050 Master Transportation Plan", "type": "Feature Layer", "description": "The 2050 Master Transportation Plan shows a master street network for the City of Chesapeake. It was created by combining traffic demand model data with state centerline data. It shows both existing roads and proposed future roads with projected 2050 traffic volumes. It was adopted as part of the 2045 Comprehensive Plan by City Council on January 20, 2026. Future updates: This layer iwill be updated periodically to include new roads recommended by adopted Small Area Plans or City Council actions. Coordinate System: VA State Plane South (EPSG 3968)The 2050 MTP layer contains a myriad of fields. A brief description is provided below.Road Classificationlane_type - Road type (8 Lane Freeway, 6 Lane Aerial NEW, etc.) - This layer is used for the map symbology it combines road type, number of lanes, or new or existing roadwayssegment_exists - Y = existing road; N = proposed roadRoad Namesstreet_name - this layer combines the street name, type, and directional prefixes and suffexesrte_name - route nameTraffic Model Networkid -Link ID in the traffic modela - Node IDS (shows direction of travel see Node.shpb - Node IDS (shows direction of travel see Node.shpdistance - actual road length in feet2050 Traffic Volumesam_v - AM peak hour volumepm_v - PM peak hour volumemd_v - midday peak hour volument_v - nighttime peak hour volumeallday_v - Total daily volumeRoadway Capacityam_link_ca - AM peak capacitypm_link_ca - PM peak capacitymd_link_ca - Midday peak capacitynt_link_ca - Nighttime peak capacityTo find congested roads, compare volume vs capacity. If pm_v > pm_link_ca, the road is over capacity.Road Characteristics:factype - road classification (1 = Interstate, 3 = Prinicipal Arterial, 4 = Major Arterial, 5 = Minor Arterial, 6 = Collector, 8 = Local)lanes - number of lanese-lanes - existing lanesp-lanes - proposed lanesFields that are not needed but are in the table. The alias has been updated to say these fields are not needed.:Processing leftovers - objectid_1, objectid_12, fid1, fid2, shape_length_1, shape_length12VDOT tracking stuff - rcl_id, vdot_edge_id, local_id, mfips, geometry_source, geometry_edit_date, street_name_source, address_range_sourceAddress ranges - left_from_address, right_to_address, etc - not used in MTPStreet name parts - street_prefix_direction, street_suffix, etc. - The street names have been combined into a single layerOther technical fields - mtfcc, segment_type, reversibleMiscelaneous - WSP edit, dual_carrier, one way, reversibleThis data layer was updated to include complete field aliases and the fields were rearranged so that the ones that were not needed appear at the end of the table.The Virginia Geographic Information Network (VGIN) has coordinated and manages the development of a consistent, seamless, statewide digital road centerline file with address, road name, and state route number attribution, as part of the Virginia Base Mapping Program (VBMP). The Road Centerline Program (RCL) leverages the Commonwealth's investment in the VBMP digital orthophotography and is focused on creating a single statewide, consistent digital road file. The RCL data layer is a dynamic dataset supported and maintained by Virginia's Local Governments, VDOT, and VGIN. VBMP RCL is extracted and provided back to local governments and state agencies in many geographic data sets every quarter.
