Performance Management: Data Collection
- Short-Term Traffic Count Request For Proposal (RFP)- The purpose of this RFP is to select a qualified vendor to collect over 2,450 short-duration counts (48 hour) in support of our Traffic Analysis & Monitoring Program and the Federal Requirements. This contract will result possibly in a five (5) year agency contract between UDOT and the selected vendor(s), with no renewable options.
- Continuous Count Stations (CCS) Field Comparison Analysis- A statistical analysis is required to evaluate the accuracy and quality of the data collected by a different traffic counter radar technology in comparison with UDOT’s existing continuous count stations traffic counters in order to determine if different counter technology could be used, either in place of or to supplement existing technologies.
- Continuous Count Stations(CCS) Field Application Development- The CCS Field Collector App is being developed to be utilized as a primary tool to help deploy work orders for repairs from the office, and give field technicians access to full details of each site for hardware inventories, and the capability to update and log repairs and maintenance. Helping work towards a paperless environment, as well as utilizing GIS tools, will allow us to not only more quickly and easily track the CCS system, but bring transparency and enhance our performance measures with data readily available to the department.
- Continuous Count Stations (CCS) Expansion in Utah County- Additional installations of CCS in several locations on I-15 and other major routes in Utah County. These additional installations will help to fill the existing gaps in our CCS coverage and will also server MAG for their planning purposes in Utah County. This project is funded by the Mountainland Association of Government (MAG) and this project will go for advertisement this summer.
- Solar Energy Development on UDOT's Right-Of-Way Project (ROW)- As part of a TRB implementation project, UDOT began to explore ROW renewable energy solar installations. In December of 2017, UDOT issued a Request for Information (RFI) asking about the feasibility of pursuing solar projects. UDOT received six responses, all of which supported putting renewable energy on UDOT ROW and reported that UDOT could break even or even save money through a power purchase agreements (PPA). UDOT is now moving forward with developing the planning document and then a Request for Proposals (RFP).
- Evaluation of Skid Resistance Data and Pavement Texture Data- Skid resistance and pavement texture data are important measures of pavement surface characteristics which ultimately affects the safety of every commuter during wet pavement condition. However, there is little understanding of the correlation between the two and greater role that texture could play in ensuring safer highways. If the relationship holds true for conditions in Utah, than pavement texture data can be used as a screening tool to develop a more strategic data collection plan for Skid Number assessments.

Traffic Data & Monitoring Programs
A traffic monitoring program is important from a statewide perspective to meet Federal and State requirements and is used to monitor travel primarily on State system and Federal-Aided roads. UDOT’s Traffic Monitoring Program is designed to collect primarily three types of data: volume, classification, and speed. Each type of data can be used for many purposes, including tracking traffic volume trends on important roadway segments; providing input to traffic management and traveler information systems; determining truck travel patterns; providing input for safety and design studies along with roadway performance monitoring; and for providing data for programs such as the Highway Performance Monitoring System (HPMS). Traffic data reported to FHWA are used to apportion funding to States from the U.S. Highway Trust Fund. Proper support and funding of traffic counting programs is critical to ensure the State data collection remains up to date and is providing the best possible data.
Skid resistance data is collected statewide for both network and project levels. This data is collected as part of the UDOT Pavement Friction Management and Highway Safety Improvement Program and per FHWA Technical Advisory. Skid data is typically collected at 2 locations/mile including bridge decks, and as needed on mainline highways and according to ASTM E274. Project Level skid data collection is completed as requested on bridge decks and per UDOT Standard Specification 03375. Skid data and wet pavement crash analysis are performed and the data is uploaded to Uplan.
