Chapter 4
DATA COLLECTION PROCESS

This Chapter describes the general methods used to conduct a roadway inventory. The road inventory types are summarized graphically and by narrative. Process steps are then provided in detail. A basic data collection process is shown using the Active On the SHS inventory process to explain in detail how inventories are conducted. A Data Collection Matrix is provided in the Appendix to assist in tracking the required Features and Characteristics. It displays the data elements to be collected according to functional classification and road ownership.

Roadway Inventory Types

Data collection of required Features and Characteristics for any given roadway is dependent on the Section Status (Feature 140), the Functional Classification (Feature 121), and the Urban Classification (Feature 124) of the roadway. Other roadway data collection requirements may be necessitated by data needs for the Strategic Intermodal System (SIS), Work Program, Small County Road Assistance Program (SCRAP), and the Transportation Regional Incentive Program (TRIP). These important criteria determine the amount of data needed for reporting purposes and funding. This Chapter discusses the inventory requirements based on the basic types of roadway Section Status: • Active On the SHS • Active Off the SHS • Active Exclusive Also included in this Chapter are the inventory requirements for Local Roads and New Construction. HPMS inventory requirements are discussed in Chapter 5.

Chapter 4 – Data Collection Process

BASIC DATA COLLECTION PROCESS
The data collection includes these basic activities or processes. 1. Pre-Inventory Process – Preparations before going into the field include developing an inventory schedule and collecting administrative data. 2. Inventory Process – Physically gathering, inputting, editing, and correcting field data. 3. Post-Inventory Process – Updating the Roadway Inventory Tracking Application (RITA) and District Straight-line Diagrams (SLDs) server. The final step is notifying TranStat. More steps may have to be performed to ensure accuracy

Chapter 4 – Data Collection Process

ACTIVE ON THE SHS INVENTORY
Generate schedule reports in RITA, the RCI 5-year Inventory Schedule Report, which details the 5-year inventory cycle. Select Roadway ID to inventory from the Inventory Schedule Spreadsheet. Collect and review construction plans, videologs, bridge reports, SLDs and basemap. Collaborate with other District offices if necessary. Collect data for elements not visible in the field. Gather equipment and verify that it is in working condition. Do vehicle safety inspection. Check tire pressure and calibrate DMI.

Drive through and establish roadway length. Mark structures, facility crossings and other items with orange paint. Record Point and Length Features beginning and ending points. Refer to the “Five Steps in RCI Field Inventory” found later in this chapter. Reconcile measured milepoints to database; update if necessary. RCI Edit program will indicate errors (e.g., overlaps, missing data). Revise the date of the actual field inventory and database input. If basemap and final RCI mileage length are out of tolerance, or incorrect alignment in basemap, submit an RCI/GIS Basemap package to TranStat.

Create graphical representation of Characteristics of a roadway. Download ASCII file into SLD Diagrammer as a DXF file. Edit output in MicroStation. Include five-year re-inventory date and revisions. Update the District SLD Server. Revise the date of the actual SLD production in the Roadway Inventory Tracking Application (RITA). Notify Transtat and District users of SLD update Chapter 4 Page 3
