Circular Economy in Winter Road Maintenance: A Simulation Study
نویسندگان
چکیده
This study analyzes the sustainability of circular economy model on winter road maintenance. Winter maintenance involves plowing snow, spreading abrasives, and then sweeping collecting remaining abrasives at end season. Traditionally, in linear approach, collected sweepings are landfilled, which incurs landfilling costs for resources that could be reused. To address this issue, we consider option recycling use following seasons. We develop a discrete-event simulation estimates economic environmental benefits option. Using data from case highway Quebec, Canada, shows introducing practices results less material going to landfills, lower costs, aggregates virgin materials, CO2 emissions compared approach. A subsequent sensitivity analysis reveals quantity greatly influences outcomes.

Probabilistic Weather Forecasting for Winter Road Maintenance
Road maintenance is one of the main problems Departments of Transportation face during winter time. Anti-icing, i.e. applying chemicals to the road to prevent ice formation, is often used to keep the roads free of ice. Given the preventive nature of anti-icing, accurate predictions of road ice are needed. Currently, anti-icing decisions are usually based on deterministic weather forecasts. Howe...
متن کاملAutomated Winter Road Maintenance Using Road Surface Condition Measurements
Real-time measurement of tire-road friction coefficient is extremely valuable for winter road maintenance operations and can be used to optimize the kind and quantity of the deicing and anti-icing chemicals applied to the roadway. In this project, a wheel based tire-road friction coefficient measurement system is first developed for snowplows. Unlike a traditional Norse meter, this system is ba...

This thesis presents an application of Work Domain Analysis (WDA) to the domain of Winter Road Maintenance Operation (WRM). WDA is the first phase of Cognitive Work Analysis (CWA), a methodology for analyzing complex socio-technical systems. WDA can help to structure system information in a manner that is meaningful for decision making and computer-based information system design. The Abstracti...
