Connecticut Route Segments is a 1:100,000-scale, feature-based layer developed for the purpose of creating the Connecticut Routes layer. The Connecticut Route Segments layer includes Interstate Highways, US Routes, State Routes and route connectors in Connecticut based on information from the U.S Bureau of Census that was published for Connecticut by the University of Connecticut, Center for Geographic Information and Analysis. The Connecticut Route Segments layer details a network of automobile route segments and represents individual Interstate Highways, US Routes, State Routes and connectors as sets of connecting and intersecting line features. Individual line features begin and end at intersections with other routes. Attributes include route class and route number for each line feature (route segment). Types of route class include Interstate Highway, US Route, State Route, and connectors. In order to reflect the complexity of the route network where routes occasionally merge together and share the same line features at bridge crossings or through metropolitan areas, a single line feature may depict the location of up to five different routes. The Connecticut Route Segments layer is based on information compiled for the year 2000 and may not necessarily depict current conditions. The layer does not include local roads, highway entrance and exit ramps, highway rest areas, exit numbers, house address, traffic direction, or traffic volume information. Features are linear and represent divided and undivided route centerlines mapped at 1:100,000 scale (1 inch = 1.578 mile).
Connecticut Route Segments is an intermediate spatial data product developed for the purpose of creating, maintaining, and updating the 1:100,000-scale Connecticut Routes layer. The line feature topology and attribute information are designed to support an automated process with ArcView 3.3 that creates the Connecticut Routes layer. The Connecticut Route Segments layer has no other known purpose. Nevertheless, it may have potential value in other applications due to the quality and accuracy of the route class and number attribute information that was carefully attributed, checked and compared with Connecticut State Tourism Map 2002-2003 published by the Connecticut Department of Transportation. Use the derivative product, the Connecticut Routes layer, to cartographically depict routes with highway and route number shields on a map. Each route in the Connecticut Routes layer is depicted as a continuous, non-intersecting line feature that is the result of merging (appending) line features from the Connecticut Route Segments layer.
The ArcView 3.3 Avenue Script that creates the Connecticut Routes shapefile from the Connecticut Route Segments shapefile is named zViewMakeRoutes.txt and is included with the Connecticut Route Segments shapefiile download from the State of Connecticut, Department of Environmental Protection Website. This script merges all linear segments that comprise each route in the Connecticut Route Segments shapefile into a single, continuous linear feature for the Connecticut Routes shapefile.

The Connecticut Routes Segments layer is derived from the Connecticut Street Network State Plane, TIGER/Line 2000 layer, which was compiled and published by Ellen Cromley and Richard Mrozinski from the University of Connecticut, Center for Geographic Information and Analysis.
The Connecticut Route Segments layer does not retain the full breadth of feature types in the source layers originally compiled and published by the U.S. Bureau of Census or the University of Connecticut, Center for Geographic Information and Analysis. Rather, the Connecticut Route Segments layer is simpler and comprised of a subset of four basic feature types: Interstate Highways, U.S. Routes, State Routes, and connectors. Each line feature is capable of describing one or more route due to the presence of five pairs of CLASS and ROUTE fields that can record combinations of (merged) routes for the same route segment. This multi-field approach guarantees similar geomtery (shape) along multi-route segments without resorting to duplicating features. The names of these paired fields are CLASS1 and ROUTE1, CLASS2 and ROUTE2, CLASS3 and ROUTE3, CLASS4 and ROUTE4, CLASS5 and ROUTE5. Note, each route is always recorded in the same set of paired fields. For example, US Route 44 is always attributed in the (fifth) CLASS5 and ROUTE5 field pair, where CLASS5="US Route" and ROUTE5="44" Additionally, line features where US Route 44 and US Route 6 merge are attributed with CLASS4="US Route", ROUTE4="6", CLASS5="US Route" and ROUTE5="44". Line features where these two routes merge with Interstate 84 are additionally attributed with CLASS1="Interstate" and ROUTE1="84", and so on. There is no real logic for determining which set of paired fields is used to record a particular route other than an attempt to minimize the number of paired fields necessary to accomodate all possible combinations of multi-route segments. Values are within defined domains. The accuracy test for the CLASS(1-5) and ROUTE(1-5) attribute values was conducted by comparing the routes as they are published on the Connecticut State Tourism Map 2002-2003 with interactive displays of the routes segments on a computer graphic system. Each route was individually tested by visually inspecting and comparing its geometry in relation to road features in the Connecticut Street Network State Plane, TIGER/Line 2000 layer, which was compiled and published by the University of Connecticut, Center for Geographic Information and Analysis. Each route was individually highlighted in color and tested one at a time. Several tests were made to compare, edit and verify CLASS and ROUTE attribute values. Attribute values for the LEGEND field reflect the highest of the CLASS(1-5) values where Interstate is highest and connector is lowest. CONNECTOR records the name of the connector. All values are manually entered, but later programmatically validated for spelling consistency, etc.
Line features conform to the following topological rules. Lines are single part. There are no duplicate lines. Lines do not self overlap. Lines do not overlap other lines. Lines intersect only at nodes, and all nodes anchor the ends of lines. Lines do not overshoot or undershoot other lines they are supposed to meet and intersect. The tests of logical consistency were performed by the State of Connecticut using ESRI ArcInfo software to maintain feature topology in ArcInfo coverage format. The data is topologically clean. The ArcInfo Clean function was repeatedly used following edits to verify topology and enforce a minimum distance between vertices of 4 feet (fuzzy tolerance) and a minimum allowed overshoot length of 10 feet (dangle length). Due to the topology verification process, there may be minor differences in feature geometry between certain features in this layer and the original data source from the University of Connecticut, Center for Center for Geographic Information and Analysis.
The completeness of the data reflects the content of Connecticut State Tourism Map 2002-2003 published by the Connecticut Department of Transportation. This layer includes all highways and routes depicted on the Connecticut State Tourism map, with feature geometry based on information from the U.S Bureau of Census that was published for Connecticut by the University of Connecticut, Center for Geographic Information and Analysis. This data does not include local roads, interstate highway entrance ramps, exit ramps, exit numbers, rest areas. This data is not updated.
The horizonal positional accuracy of this data is no better than United States National Map Accuracy Standards for 1:100,000-scale maps . According to this standard, not more than 10 percent of the points tested are to be in error by more than 1/50 inch (167 feet) measured on the publication scale of a USGS 1:100,000-scale topographic map. The following description of horizontal accuracy is taken from the metadata for the data source upon which the Connecticut Route Segments layer is based, which is the Connecticut Street Network State Plane, TIGER/Line 2000 layer. It cautions against using these data for measurement and detailed, large scale mapping purposes.The information presented in these files is provided for the purposes of statistical analysis and census operations only. Coordinates in the TIGER/Line files have six implied decimal places, but the positional accuracy of these coordinates is not as great as the six decimal places suggest. The positional accuracy varies with the source materials used, but generally the information is no better than the established national map Accuracy standards for 1:100,000-scale maps from the U.S. Geological Survey (USGS); thus it is NOT suitable for high-precision measurement applications such as engineering problems, property transfers, or other uses that might require highly accurate measurements of the earth's surface. The USGS 1:100,000-scale maps met national map accuracy standards and use coordinates defined by the North American Datum, 1983. For the contiguous 48 States, the cartographic fidelity of most of the Census 2000 TIGER/Line files, in areas outside the 1980 census Geographic Base File/Dual Independent map Encoding (GBF/DIME) file coverage and selected other large metropolitan areas, compare favorably with the USGS 1:100,000-scale maps. The Census Bureau cannot specify the accuracy of features inside of what was the 1980 GBF/DIME-File coverage or selected metropolitan areas. The Census Bureau added updates to the TIGER/Line files that enumerators annotated on maps sheets prepared from the Census TIGER data base as they attempted to traverse every street feature shown on the Census 2000 map sheets; the Census Bureau also made other corrections from updated map sheets supplied by local participants for Census Bureau programs. The locational accuracy of these updates is of unknown quality. In addition to the Federal, State, and local sources, portions of the files may contain information obtained in part from maps and other materials prepared by private companies. Despite the fact the TIGER/Line data positional accuracy is not as high as the coordinate values imply, the six-decimal place precision is useful when producing maps. The precision allows features that are next to each other on the ground to be placed in the correct position, on the map, relative to each other, without overlap.
Line features from the Connecticut Street Network State Plane, TIGER/Line 2000 layer with LEGEND attribute values equal to "Major Highway" or "Highway". The Connecticut Street Network State Plane, TIGER/Line 2000 database is a statewide database of address-ranged street segments compiled from the Census 2000 TIGER/Line files. In order for others to use the information in the Census TIGER data base in a geographic information system (GIS) or for other geographic applications, the Census Bureau releases to the public extracts of the data base in the form of TIGER/Line files. The University of Connecticut Center for Geographic Information and Analysis prepares databases such as The Connecticut Street Network State Plane, TIGER/Line 2000 database from the public extracts released by the Census Bureau as a service to the University community and the state. TIGER, TIGER/Line, and Census TIGER are registered trademarks of the U.S. Census Bureau.

Route Segment Geometry Creation - The process of creating the Connecticut Route Segments layer first involved developing a statewide layer with line features for all routes that conformed to the following topological rules. Lines are single part. There are no duplicate lines. Lines do not self overlap. Lines do not overlap other lines. Lines intersect only at nodes, and all nodes anchor the ends of lines. Lines do not overshoot or undershoot other lines they are supposed to meet and intersect. Lines may end without intersecting another line (deliberate dangle acceptable). Intersections must be with three or more lines (no pseudo nodes). These topological rules were applied to 1:100,000-scale based line features and ensure routes would properly connect (no gaps) and intersect each other. To begin creating the desired feature geometry, line features that defined routes in the Connecticut Street Network State Plane, TIGER/Line 2000 layer were extracted and separately saved to a new layer in Shapefile format. Features that were extracted from the Connecticut Street Network State Plane, TIGER/Line 2000 layer were based on LEGEND attribute values equal to "Major Highway" or "Highway". The resulting Shapefile included 199,636 features and depicted the geometry of most Interstates, US Routes, State Routes, and connectors. There were nearly 200,000 features in the resulting Shapefile because, for the most part, each feature represented a small section of a route that intersects with other local roads so many routes were comprised of hundreds of short features connecting to each other. After comparing the resulting Shapefile to the Connecticut State Tourism Map published by the Connecticut Department of Transportation, additional edits to the resulting Shapefile were necessary because there were small gaps along some routes (missing features) and the Shapefile included some roads that were not designated as routes on the Connecticut State Tourism Map. Since the overall process of creating the Routes Segments layer was to first establish the correct geometry and later attribute line features with route class and number information, all attributes (fields) were deleted from the Shapefile. The physical remove of attributes did not represent a loss of detailed information that could not be created later because the route number information was not consistently assigned to individual features in the Connecticut Street Network State Plane, TIGER/Line 2000 layer. Next, each route was carefully followed on the Connecticut State Tourism Map and visually compared to its geometry in the Shapefile. Any gaps along each route in the Shapefile were replaced with line segments manually copied and pasted from the Connecticut Street Network State Plane, TIGER/Line 2000 layer. One by one, each route was inspected to ensure that a continuous route could be created from a series of short line features that properly connected to and intersect with all other routes in the Shapefile. Where routes merged, only one set of line features was established (no duplicate features allowed). All line features from the initial extraction that did not appear as routes on the Connecticut State Tourism Map were deleted from the Shapefile. Once the geometry for 8 Interstates, 7 US Routes, 209 State Routes, and 10 connectors was systematically inspected, the Shapefile was converted to ArcInfo coverage format in order to more strictly enforce line topology rules. For example in ArcInfo format, line features were unsplit (merged) so that they only begin and end at intersections with other routes. This rule reduced the number of line features from approximately 200,000 to 2,000 and preserved the orginal geometry that define individual routes. Smaller road sections from the original Connecticut Street Network State Plane, TIGER/Line 2000 layer were merged by this rule to form longer features with the combined geometry. The ends of approximately 20 line features were manually moved no more than about 50 feet in order to close gaps along individual routes or at intersections. The ArcInfo Clean function was repeatedly used following edits to verify topology and enforce a minimum distance between vertices of 4 feet (fuzzy tolerance) and a minimum allowed overshoot length of 10 feet (dangle length). Due to the topology verification process, there may be minor differences in feature geometry between certain features in this layer and the original data source from the University of Connecticut, Center for Center for Geographic Information and Analysis. Finally, the layer was converted from ArcInfo coverage to Shapefile format once it was determined that it captured all necessary geometry and conformed to the topology rules.

Assign CLASS and ROUTE attribute values - Five pairs of CLASS and ROUTE fields were added to the Shapefile in order to take into consideration situations where routes merge onto a single line feature. This multi-field approach guarantees similar geometry (shape) along multi-route segments without resorting to duplicating features. The names of these paired fields are CLASS1 and ROUTE1, CLASS2 and ROUTE2, CLASS3 and ROUTE3, CLASS4 and ROUTE4, CLASS5 and ROUTE5. The domain for the CLASS field consists of "Interstate", "US Route", "State Route", and "Connector". The associated ROUTE field stores the corresponding route number as a string. Note, each route is always recorded in the same set of paired fields. For example, US Route 44 is always attributed in the (fifth) CLASS5 and ROUTE5 field pair, where CLASS5="US Route" and ROUTE5="44" Additionally, line features where US Route 44 and US Route 6 merge are attributed with CLASS4="US Route", ROUTE4="6", CLASS5="US Route" and ROUTE5="44". Line features where these two routes merge with Interstate 84 are additionally attributed with CLASS1="Interstate" and ROUTE1="84", and so on. Beginning with Interstates, each route was carefully followed on the Connecticut State Tourism Map so that the corresponding line features in the Shapefile could be manually selected and assigned CLASS and ROUTE attribute values using ArcView 3.3 software. All values were manually entered, but later programmatically validated for logical and spelling consistency, etc. Once the CLASS and ROUTE attribute values were correctly attributed, the LEGEND field was added to easily classify (multiple route type) features and cartographically represent them on a map. Values were attributed programatically and assigned a value of "Interstate", "US Route", "State Route" or "Connector" by comparing and taking the most dominant (route type) of the CLASS1, CLASS2, CLASS3, CLASS4 and CLASS5 attribute values. For example, if a route segment was both part of an Interstate and US Route, then the value of the LEGEND attribute was set to be "Interstate" so as to cartographically represent the line feature as an Interstate.
