AbstractRoad network patterns influence traffic operational performance and road safety. A precise description of road network patterns can provide useful guidance for both design and improvement of road systems. Most previous studies have classified road network patterns using a visual inspection method. Although visual inspection is valuable in practical applications, it can be subjective and time consuming. Hence, a more reliable, automated, and quantitative approach for the classification of road network patterns is required. The objective of this study is to develop and apply a quantitative method for network pattern classification. Data analyzed are from 718 traffic analysis zones (TAZs) in Florida's Hillsborough County. Six quantitative metrics, geometric and topologic, were analyzed, and their ability to classify different road network patterns were compared. Then, a multinomial logit model was developed to classify various network patterns using the six metrics. The results show that meshedness coefficient, proportion of cul-de-sacs, and proportion of 4-legged intersections were the three most significant variables in determining network patterns. Finally, this quantitative method was validated using TAZ data from Florida's Orange County, with an accuracy of 74.7%. This accuracy demonstrates the potential of the method in automatically and reliably classifying road network patterns.

    HighlightsA better description of road network patterns can provide useful guidance for design and improvement of road systems.Most previous studies have classified road network patterns using a visual inspection method.Both geometric and topologic metrics were used to classified road network patterns.A multinomial logit model was developed to classify the network patterns objectively with an accuracy of 74.7%.
