Polygon layer of NY census tracts that includes data from EPA that attempts to approximate inherent disadvantages due to location, such as walkability, air pollution, average commute, and more. Mapped field is [Disadvantaged communities index percentile rank]. Added field [CPCS_Flag] denotes proximity to Freight Core Highway Network if applicable, used for creation of multiple maps for updated freight plan. (x2041_Disadvantaged_Populations_NY)
Bottleneck Locations
Primary bottleneck TMC’s are defined as those sections of interstates that suffer from either excessive congestion or from a reliability issue and moderate or excessive congestion.
These sections create boundaries to distinct bottleneck locations and segments not identified between a distinct start and end location are considered part of the bottleneck.
Visual inspection or additional data may extend the boundaries of the bottleneck location beyond the bounding
Definitions
Geographic Areas consist of Upstate, Suburban and Urban.
- Urban Area consists of the five counties of New York City (NYSDOT Region 11).
- Suburban Area consists of Rockland, Westchester, Suffolk, Nassau, Ulster, Orange, Dutchess, Putnam and Columbia County (NYSDOT Regions 8 and 10).
- Upstate Area consist of the remaining counties of New York State (NYSDOT Regions 1 -7 & 9).
TMC’s should only be considered for metric purposes if they meet the following criteria:
- TMC must be part of an Interstate
- TMC length must be .25 mile or more
- Percent BINS reporting must be 30% or higher
- TMC must have an NHS value of 1
Excessive congestion is determined by the most recent full year of NPMRDS data. For each geographic area, the Annual Hours of Excessive Delay using the Time of Excessive Delay (TED) value with parameters RIS based AADT, Freeflow Based Threshold Speed, Vehicle Hours Per Mile is used. Note the actual values used will change over time and that no strict methodology was used to determine break values. Refer to Table 1 for break values used in 2022.
Reliability issues are identified by the maximum Truck Travel Time Reliability metric for 3 consecutive years if and only if all three years had a value. Note that due to the pandemic, 2022 measures included years 2021, 2019 and 2018 as it was felt metrics from 2020 would be unstable. Each Geographic Area used a non-formulaic break point threshold for determining Poor Reliability. Refer to Table 1 for values used for 2022.

}Polyline layer of the national highway system (NHS). Includes road name and alternate name, as well as NHS and NFHN code which was used to designate the Primary Highway Freight Network and PHFS connectors. (x2001_National_Highway_Freight_Network)
Polyline layer of merged EIA pipeline layers (Petroleum product, crude oil, HGL, and natural gas). Can be differentiated by source layer information field. Natural Gas EIA pipeline data was filtered for Status IN 'Operating' AND TYPEPIPE IN 'Interstate,'Intrastate'
This is the enhanced TMC Network Shapefile that is built each time Raw NPMRDS data is processed into the Production database. This shapefile includes a variety of spatial datasets that provide additional network attributes (e.g., speed limits, MPO boundaries, NYSDOT region boundaries). This shapefile also calculates directionality from NPMRDS data for use in AADT disaggregation for the PHED measure.
Point layer of bridges in New York, which includes bridge type, material type, BIN number, CONDITION status, and MINVCON/MINVCUNDER (which serves as the minimum vertical clearance). FCHN field denotes whether the bridge is within 600ft of the Freight Core Highway Network (source 2002). (x2029_NY_State_Bridge_Inventory)
A selection of preformance measures and metadata published on the tmc network. Includes TTTR, TED, and bottleneck data. FCHN field denotes whether segment is on the Freight Core Highway Network. Used in bottleneck data as well. (x2008_TMC_Network_Performance_Measures)
