Abstract
Sustainable urban road route planning should provide functional, economical, engineering-reasonable, people-friendly, and eco-friendly road schemes to meet traffic-related demands and promote social development. However, how to realise sustainable urban road route planning has not been fully discussed. This research systematically explores sustainable urban road route planning based on the design science research (DSR) paradigm from the perspective of the overall framework, factors that should be considered, digitalisation and parsing methods for the considered factors, multi-criteria decision making (MCDM) method for factor evaluation, and road route generation methods. A systematic literature review, two rounds of questionnaire surveys based on the Delphi method for selecting factors, three exploratory focus group interviews, and questionnaire surveys for factor evaluation using MCDM were conducted to explore all the perspectives qualitatively and quantitatively to develop five versions of artefacts iteratively. Traffic and development factors are considered as demands, and cost, social, environmental, and engineering factors are considered as constraints. Various digitalisation and parsing methods for all the factors are proposed, which can be categorised into direct assignment methods, spatial analysis methods, complex professional analysis methods, and other methods. The MCDM-GIS method using least-cost wide path analysis is suggested for road route generation. The brush head and restricted areas are defined. The proposed method can consider both new road construction and existing road widening. In the artefact, choice and accessibility of road network based on space syntax, traffic congestion, road network connectivity, local development, building demolition and costs, cultural heritage protection, population, land use impacts on the environment, carbon emission and air pollution, noise, engineering risk areas, etc., are considered comprehensively. After the development, the artefact was evaluated by an urban road route planning case in the London Borough of Bromley. After that, two confirmatory focus groups are conducted with experts to evaluate the artefact.
