What does Connected Vehicle technology do and how do we know if it’s working?: Local, state and federal transportation agencies are working collectively with Connected Vehicle (CV) device manufacturers, the automotive industry and telecommunications providers to test and evaluate technology that will enable cars, buses, freight vehicles, and roadside infrastructure to communicate with each other. The influx of DSRC radio deployment within Colorado has ushered in this new realm of roadway communication to increase roadway safety and mobility. This presentation will provide an overview of how this CV technology works and shares how we have been testing the coverage and performance of the roadside and on‐board units. This presentation will appeal to those that are curious about the fundamentals of why and how Colorado public agencies are deploying this equipment along hundreds of miles of interstates and hundreds of intersections. The future of roadway safety depends on the ability for roadway users to receive the information in a timely manner. We will share visuals of the data along with the methodology being used to determine where to place this infrastructure.

Learning Objectives: 1) Understand the current level of Dedicated Short Range Communication (DSRC) radio deployment within Colorado; 2) Gain a general understanding of DSRC radio communication; 3) Understand the process for testing DSRC radio coverage

Small Cell Light Poles & Traffic Structures: Small Cell is taking the industry by storm and many cities and specifiers are unsure what to do.

Learning Objectives: 1) What is small cell; 2) Things to consider when trying to implement small cell sites in your city; 3) Why existing equipment is not suited to house this equipment; 4) Steps that can be taken to start a specification

Utilizing Big Data for Non‐Motorized Activity Evaluation: The practice of utilizing big data for non‐motorized activity evaluation is new and somewhat experimental. The assessment of Colorado Strava data advances bicycle activity analysis and stands as a case example of how a state agency might evaluate similar types of information about bicycling to improve understanding of bicyclist behavior and the non‐motorized functions of a transportation system.

Learning Objectives: 1) Developing best practices for quality control of crowd‐sourced bicycling data as it relates specifically to mobile application data sources; 2) Using statistical methods to correlate bicycle counter data with Strava user data to develop parameters for extrapolating actual activity from Strava trip counts; 3) Understanding the identified shortcomings of the assessment (e.g., issues with data quality, sample size, and data integration) and the considerations for others interested in conducting similar assessments and furthering this type of work.

Addressing the Controversy - A Defendable Method for Determining Potential Red-Light Camera Locations: This session will provide an overview of the controversy surrounding red-light cameras, discuss research related to the topic and outline a defendable methodology for determining potential locations where the benefits outweigh the disadvantages.

Learning Objectives: 1) Learn about the controversy regarding red-light cameras; 2) Learn about red light camera research; 3) Learn a methodology to determine potential locations where red-light cameras might make sense

Linking Lookout in Golden, CO: A Multi-Purpose Structure: For a great many years, the Denver metropolitan area has sought a completion for a highway that circles the region. But a multi-lane highway through Golden would completely cut off the neighborhoods west of the highway from the Golden community. To protect against the potential impacts of such a road while recognizing the need for effective transportation, Golden developed a plan that includes limited lanes, noise barriers, reduced speeds and interchanges designed to unite rather than divide the community. The Golden Plan was adopted in November 2003 and became the document that Golden used to negotiate highway design through town. The first project towards achieving this overall plan would be to create a grade separated crossing of the 19th Street and US6 intersection. The neighbors west of the highway (US6) are at the base of the popular Lookout Mountain, which overlooks the entire metro region and houses the Buffalo Bill Museum. The goal of this project was to facilitate the transportation needs as well as connecting, or “linking” the Lookout Mountain communities with the rest of Golden. Hence, the name Linking Lookout.

The Linking Lookout Bridge was designed as an urban park as well as a major multi-modal transportation conduit to provide a safe, quiet and aesthetically pleasing passage over a loud and fast-moving highway. To facilitate the grade separation, the highway was lowered by 20-feet. This necessitated nearly 70,000 square feet of retaining walls that are predominately soil nail walls with precast concrete facing. MSE and gravity boulder walls were also utilized. The bridge consists of a 125-foot-long by 280-feet-wide prestressed concrete butted-box beam superstructure. The substructures include integral abutments on a single row of driven H-piles, and a cap & column pier supported on drilled caissons. To create a quiet urban park setting atop a noisy highway, up to 10 feet berms with and trees were added on top of the bridge deck, along with picnic tables, park space, community trails and a small amphitheater. To minimize the load on the structure, light-weight engineered fill and styrofoam blocks were utilized. Waterproofing of the bridge deck below the earthen fill was a critical consideration because the structure would be covered by earth, grass, and pavement, and could not be inspected from above. A proprietary system was therefore developed that supplements membrane with root barriers and strip drains. Presentation will discuss design development and the lessons learned from the design of this unique structure.

Learning Objectives: 1) Understanding of the advantages and disadvantages of earth-covered structures; 2) - Identify the unique design criteria needed for earth-covered structures;  3) - Recognize the lessons learned from the Lookout lid project for future projects
