Abstract:

One of the most contributing factors to fatal motor vehicles crashes is the inadequate and poorly maintained pavement marking. The cost of these crashes is estimated to range between 10-25 billion Canadian dollars annually. Consequently, the different companies/authorities that manage pavement marking should set a target for themselves to be more cost efficient through building a strategic plan to renew and restripe pavement marking. The objective of this paper is to develop a methodology and model(s) that predict the performance of the pavement marking at different average annual daily traffic, percentage of trucks, age, and type of road. Due to the typical scarcity of data, particularly for performance of pavement marking, there is an essential need to predict this performance. In order to achieve this objective, a sound technique, such as unsupervised neural network, is used. Therefore, the developed models are designed using unsupervised neural network in conjunction with regression analysis. Data for this research were collected from the city of Ottawa, Ontario, Canada for the Alkyd paint material. The developed model is validated and the results show that the percentage average validity is 73%. Similarly, the fitness function value is found to be 789; which means the developed model is a sound fit. Marking performance is assessed using a performance scale, which numerically ranges from “1” to “5” and linguistically from “Excellent” to “Critical”, respectively.
