Evaluation of the Impact of Presence Lighting and Digital Speed Limit Trailers on Interstate Speeds in Indiana Work Zones

Work zone safety continues to be one of the important focus areas for transportation agencies. Previous studies have identified that vehicle speed and lighting conditions are significant risk factors impacting work zone safety. This study evaluated the impact of the use of presence lighting and digital speed limit trailers on nighttime motorist speeds using commercially available connected vehicle speed data. Geospatial analysis was conducted on over 500,000 connected vehicle records to linear reference nearly 18,000 records from 195 unique trajectories to study section during the study period of 2 days. Results showed that median speeds reduced by 4 to 13 mph from 11PM to 7AM during the deployment of presence lighting and speed limit trailers compared to base conditions. A Kolmogorov-Smirnov (KS) statistical test comparing 105 vehicles traveling through the construction zone with presence lighting and speed limit trailers with a group of 90 vehicles during base condition indicated the speeds during the deployment of presence lighting and speed limit trailers were lower than the base condition. Also, increased compliance with the 55 mph speed limit was observed when the presence lighting and digital speed limit trailers were deployed. However, there were two hours (3AM to 5AM) where speeds increased by 0 - 4 mph, perhaps due to the low volume at that hour. The encouraging results support the further deployment of presence lighting and speed limit trailers in nighttime construction zones for reducing vehicle speeds. Those future deployments should be monitored with connected vehicle speeds to collect additional data to broaden the evaluation of these speed mitigation techniques over a diverse set of construction zone activities.

Construction Workers’ Perceptions of Safety Practices: A Case Study in Mexico

Organizational characteristics and worker perceptions are among the main factors affecting the safety climate in construction sites. Although some perceptions of the workers may seem absurd to others, these components are part of their reality. Worker behavior is an extremely important factor in workplace safety as many accidents are often caused by insecure actions, in which combinations of human behavior are the consequence of such perceptions. The aim of this study was to explore workers’ perceptions of safety practices in their habitual work environment, a building site in Mexico. Worker perceptions of safety practices were captured using an instrument in which the following dimensions were taken into consideration: Education and training, Work motivation, Family and social integration, Work place integration, Safety awareness integration, and Accidents. The conclusion was that the workers have received very little education and possess a limited culture of safety awareness, which has led them to perceive that their lack of precaution is the main cause of accidents.

Overview of Safety Risk Perception in Construction

Construction industry is a generally risky business; it remains one of the most dirty, difficult and dangerous with poor working conditions. Despite recent efforts to improve site safety, it still accounts for a disproportionate number of occupational-related fatalities what is supported by statistics. According to the International Labour Organization, it accounts for 30-40% of the world＇s fatal injuries. In The European Union around thirteen employees out of every one hundred thousands are killed each year. Hence, construction site safety is a matter of global concern. However it is not easy to describe and define how to deport safely at some actual site because the workers are exposed to many safety risks varying in con^nection with conditions of the construction realization and with technologies using. The paper provides a brief knowledge from the study comparing the construction safety in Europe and North America referencing to presented statistics. There are also analyzed, described and systemized the principal groups of construction safety risks; described the interdependencies among safety risks, affecting by spatial, technological and time parameters of the building process, as well as by the site conditions.

Using Anonymous Connected Vehicle Data to Evaluate Impact of Speed Feedback Displays, Speed Limit Signs and Roadway Features on Interstate Work Zones Speeds

Annually, there are over 120,000 crashes in work zones in the United States. High speeds in construction zones are a well-documented risk factor that increases the frequency and severity of crashes. This study used connected vehicle data to evaluate the spatial and temporal impact that regulatory signs, speed feedback displays, and construction site geometry had on vehicle speed. Over 27,000 unique trips over 2 weeks on a 15-mile interstate construction work zone near Lebanon, IN were analyzed. Spatial analysis over a 0.2-mi segment before and after the posted speed limit signs showed that the regulatory signs had no statistical impact on reducing speeds. A before/after analysis was also conducted to study the impact of radar-based speed feedback that displays the motorists’ speed on a sign below a regulatory speed limit sign. Results showed a maximum drop in median speeds of approximately 5 mph. Speeds greater than 15 mph above the speed limit dropped by 10% - 15%. The reduction in speeds began approximately 1000 feet ahead of the sign and results were found to be statistically significant. The analysis also revealed that larger speed drops inside the work zone were due to geometric constraints that required additional driver workloads, especially during shoulder width changes and lane shifts. The results from this study will be helpful for agencies to understand driver behavior in the work zones and to identify proper speed limit compliance techniques that significantly reduce driver speeds in and around work zones.
