CTP 2.0 Harnessing the power of Standardization! Phase 1 Phase 2
Developing the data model, cartographic standards and map templates Phase 2 Refining the data model and building tools to automate routine tasks Phase 3 Continuous process improvement
3
Moving from shapefiles to a file geodatabase utilizes far more powerful and efficient ways of organizing, managing, and maintaining data for TPD’s planning applications. Map Attributes in GIS Shapefiles Inventory Data in Excel Old Way All data in GIS Geodatabase Excel table and other documents generated as “Reports” New Way Geodatabase features also facilitate ease of use: Field Aliases Domain Lists Feature Datasets
4
Geodatabase Features Descriptive Field Names
Field Aliases Domain Lists Feature Datasets Descriptive Field Names These descriptive names also show in the ArcMap Table of Contents!
5
Geodatabase Features Field Aliases Domain Lists Feature Datasets
6
Geodatabase Features Editing in Table Editing in Attribute Pane
Field Aliases Domain Lists Feature Datasets Editing in Attribute Pane Road Characteristics Domains and CTP Specific Domains are included!

Geodatabase Features Field Aliases Domain Lists Feature Datasets
8
Compile Supporting Data
More than 100 Atlas verified supporting datasets are included in the geodatabase All data are provided in North Carolina State Plane Feet All data are clipped to the relevant study area by issuing a single command to the clip tool The statewide geodatabase is compiled quarterly.
9
Processing Road Characteristics Creating a better starting point for CTPs
Simplify Intersections Remove breaks at intersections for non-system roads Populate Names Populate from and to intersection names Add Municipality Names using an overlay Clean up Segments Clean up segmentation that is based on a small variance, such as Right of Way All information to support capacity calculations is retained Statewide Road Characteristics – 1,061,440 to 614,830 records!
10
Integrating Long Range Planning Principles
System Facility Type Calculation Facility Type Speed Limit Access Control Median Type Through Lanes Notes Freeways >=55 Full Not null >= 4 Expressways >=45 and <=60 Limited or Partial >=4 Function Class = 2. Otherwise, classify as Boulevard. Boulevard >=30 and <=55 Limited, Partial or None Multilane Major Thoroughfare >=25 and <= 55 None null Other Major (2 Lanes) With or without a median >=2 and < 4 lanes Route Class 2 (US) or 3(NC) that do not qualifier for a higher classification based on criteria Minor Thoroughfares Not NC/US Route Class
11
Integrating Long Range Planning Principles
Urban Classification Classification Description Urban Road segment falls within a smoothed urban boundary Suburban Road segment within an MPO polygon or town limit Rural Everything else Incorporating AADT This is a spatial operation All these items are to automate the capacity look up process.
12
Other calculations Labeling fields and other standards for mxd templates. Instead of using definition queries for specific counties and other values, generalized these to simply be “on” or “off” so they could work for any study area.
13
Map Templates Cartographic Standards Map and Database connectivity
What they are and why we have them How to utilize them Cartographic Standards Document Map and Database connectivity Linking the data Map and database standardization Working with Database Output Study Roads for most Modes Working with the maps Working, Core, Analysis, Informational, and Environmental Definition Queries Working with Insets Adding new templates Working with Tables in the Database Metadata Table Recommendations and Proposals Table
14
Cartographic Standards Precisely capture all spatial and non-spatial elements of a CTP map
Mapping Subcommittee Highway Proposals - Relevant to Prioritization (SPOT) Update Highway Facility Type Classifications and definitions Update Multi-modal Classifications and definitions if needed Simplify Map Symbology (too complex) Move Map format to a primarily web based Satisfy both MTPs and CTPs (Size & scale, fewer Insets) Legal disclaimers Consider use of QR codes accessible by smart phone Consider ADA requirements
15
Cartographic Standards
Mapping Complexities 19 Recommend Classifications 4 Recommendation Maps 2 Highway Maps 1 Bike & Ped Map 1 Public Transit & Rail Map 7 Analysis Maps 8+ Informational Maps
16
Cartographic Standards Precisely capture all spatial and non-spatial elements of a CTP map
What are they? 137-page document to assist with capturing all components of a map Four Primary Topics Symbology Map Accessibility Theming and Consistency Streamline Map Creation
17
Cartographic Standards Precisely capture all spatial and non-spatial elements of a CTP map
Why have them? Standardize all CTPs, visually and allow for automation How to utilize them Templates, styles and layer files
18
Map and Database Connectivity Linking Standardized Data to Uniform Map Templates
Map templates designed specifically for CTP database Link data Standardization Quickly have a complete map
19
Public Transit Recommendations
Working With the Database Output Utilizing long-range planning principles in one feature class Study Roads for Most Modes One feature class captures most modes Highway Transit Bicycle and Pedestrian Reduces amount of linework Decreases possibility of human error Keeps data in one feature class Highway Recommendations Bike & Ped Recommendations Public Transit Recommendations
20
Working with the Maps Detailed templates to provide coverage of data features for modes and insets
Types of maps Working Environment for editing data, standards do not apply Core Recommendation maps Analysis Bike, Ped, Rail, Public Transit, & Public Transit TDI Informational Freight, Crash Locations, Bridge Deficiencies Environmental Split into five maps, approximately total of 96+ layers Core Maps Analysis Maps Informational Maps
21
Working with the Maps Detailed templates to provide coverage of data features for modes and insets
Definition Queries Database developed to remove requirement Insets Highway, Bike & Ped, BY and FY, and pedestrian analysis Additional Templates Truck Percentages & Fatal/Severe Truck Percentages Fatal/Severe Crashes
22
Working with Tables Integrate long-range planning principles for auto-generated output
Metadata Table Contains various required fields for updating templates Proposals and Recommendations Tables Works collectively with Study Roads, facilitates auto-generation
