Pavement Marking Mobile Retroreflectivity Data Collection: Applications and Return on Investment

DECEMBER 8, 2021 | 12-1 PM EST

Pavement markings provide essential roadway lane location information to both human drivers and the machine vision technology in advanced driver assistance systems. Their safety function is particularly important at night when they are often the only lane guidance to roadway users. To ensure that markings are meeting the needs of roadway users their visibility level should be monitored. The standard metric for assessing marking nighttime visibility is retroreflectivity, and the mobile measurement of retroreflectivity at posted speed limits is an effective method for monitoring marking performance. The two primary applications of mobile retroreflectivity data are timely identification of maintenance striping needs and quality assurance after marking installation. This webinar explains what a mobile retroreflectometer unit (MRU) is, provides specific examples of transportation agencies using MRU data, and defines the agencies’ return on investment.

Mitigating Explosive Threats at U.S. Airports

AUGUST 25, 2021 | 12-1PM EST

Airports serve a critical role in modern society on many fronts. Unfortunately, due to their prominent visibility and openness, airports are also a rich target for mass casualty explosive attack. Beyond the immediate human and economic consequence of such an attack, the potential also exists for triggering a cascading impact across the National Airspace System (NAS). Since the attacks of September 11th nearly 20 years ago, much has been done at the federal, state, and local levels to help provide a safer environment at airports for passengers, visitors, and staff. This presentation will go back through a brief history of requirements enacted at U.S. airports for mitigating explosive attack over the last 20 years and will also explore engineering-level approaches to implementing these requirements. The differences between implementing such countermeasures at existing facilities versus new facilities will also be discussed.

Florida Statewide Pavement Marking Data Collection and Management System

JULY 28, 2021 | 12-1PM EST

The visibility of pavement markings is an important aspect of a safe transportation system as they convey vital roadway warnings and guidance information to the traveling public. Therefore, it is beneficial to maintain acceptable visibility levels of markings on pavements under all weather and lighting conditions. To ensure the intended in-service visibility level is adequately maintained, the reflectivity must be monitored and quantified accordingly. This presentation will provide a description of the Florida Pavement Markings Management system and its subsequent implementation including FDOT’s effort to ensure the quality, consistency, repeatability, and accessibility of statewide pavement marking retroreflectivity data.

Electrically Conductive Concrete Heated Pavement Systems

APRIL 28, 2021 | 12-1PM EST

Transportation agencies spend millions of dollars to remove accumulated ice and snow from paved surfaces by using deicing chemical agents, which can cause detrimental damage to bridges and pavements. The chloride in road salt flows into our lakes, streams, and groundwater, potentially harming roadside vegetation and our environment. Electrically conductive concrete (ECON) heated pavement system (HPS) has gained attention as a promising alternative technology for preventing snow and ice accumulation and mitigating the adverse effects of using traditional snow removal methods. This presentation demonstrates the world’s first full-scale ECON-based HPS construction and operation at Des Moines International Airport and how this system can be adapted for bridge and roadway applications.
