Table 4-1. (cont) GIS coverages used in TRAKER data analysis Coverage/Fields used Coverage: 2000 TDM Filename: 2000.shp Source: COMPASS Coverage/Field Description Coverage Description: Year 2000 Traffic Demand Model analysis results. The TDM uses optimization algorithms to determine how traffic flows between Traffic Analysis Zones (TAZ). Major roadways are included as individual links in the TDM coverage. Residential areas are represented by a single TAZ, with one or more links that access the larger network. i.e individual residential streets are not represented. This coverage is used to associate TRAKER data to the major streets in the traffic demand network. Data Fields Used Field Description A, B The A and B fields correspond to node ID numbers within the network. Specifying A and B uniquely specifies a link in the TDM. Note that individual links only support traffic flow in one direction. Thus, it is possible to have two links between any two nodes, one per direction of travel. Speed (mph) Specifies the vehicle speed in miles per hour on a particular link. FTYPE A number between 1 and 20 that assigns a roadway type to the link: 1-2 ? Interstate; 3-6 ? Principal Arterial; 7-10 ? Minor Arterial; 11-14 ? Collector; 15- 18 ? Local; 19 ? Interstate Ramp; 20 ? Centroid Connector. A centroid connector does not necessarily correspond to an actual road, but rather is used as a surrogate for all traffic flow coming out of a TAZ. THRULANE COUNTY ADJCNT V1_1 Coverage: 2010 TDM Filename: 2010.shp Source: COMPASS The number of travel lanes on the link. Specifies the County that the link is located in : 1 for Ada, 2 for Canyon. Adjusted Traffic Volume on a vehicles per average weekday basis. This field isonly active if actual traffic counts have been obtained for the link. Note that the total number of vehicles traversing a link is reported. Thus, to obtain the traffic volume on a per lane basis, you must divide ADJCNT by the THRULANE field. Traffic Volume in average vehicles per weekday obtained from TDM analysis results. The total number of vehicles traversing a link is reported. Thus, to obtain the traffic volume per lane, you must divide V1_1 by the THRULANE field. Coverage Description: Year 2010 Traffic Demand Model projected analysis results. The format for this data file is the same as for the 2000 TDM coverage except that the ADJCNT field is not used. 4-4

(cont) GIS coverages used in TRAKER data analysis Coverage/Fields used Coverage: 2015 TDM Filename: 2015.shp Source: COMPASS Coverage: 2020 TDM Filename: 2020.shp Source: COMPASS Coverage: Ada streets Filename: adastr.shp Source: COMPASS Coverage/Field Description Coverage Description: Year 2015 Traffic Demand Model projected analysis results. The format for this data file is the same as for the 2000 TDM coverage except that the ADJCNT field is not used. Coverage Description: Year 2020 Traffic Demand Model projected analysis results. The format for this data file is the same as for the 2000 TDM coverage except that the ADJCNT field is not used. Coverage Description: Coverage of Ada County streets. Associated data tables include information on whether or not a particular road segment is a residential street. Data Fields Used STR_CLA Coverage: Canyon streets Filename: canstr.shp Source: ESRI Field Description Street Class. This field identifies residential road segments and is used to tie TRAKER data with residential roads that are not covered by the TDM 2000 coverage. Coverage Description: Coverage of Canyon County streets. This coverage was used to identify residential Canyon County streets. TRAKER data associated with these streets were tagged manually and this coverage was used for visual verification only. 4-5
