The Local Street System denotes the network of collectors and alleys in ablock bounded by arterials. This research aims at the analysis model for thespacing design of Local Street System. The model was designed as a multiobjectivegrey integer programming model, in which three objectives, i.e.,accessibility, mobility, and traffic safety, are considered. The constraintsincluded travel demand, emergency services, public refuge, noise, air quality,and minimum width, and depth of architectural base. Since the planning tasksare filled with uncertainties, the parameters and decision variables of modelwere both designed as grey numbers, which represented the possible rangesother than crisp values. Additionally, this research developed the approach ofGrey Integer TOPSIS for solving the developed model, and this approach canalso be applied to solve the other multi-objective grey integer programmingmodels. A mixed-use block in Dan-Hai New Town was investigated as a casestudy to justify the applicability of model. We also analyzed the influences oftraffic calming measures and parameters’ grey degree on spacing design toidentify the model’s characteristics. The results of this case study providedfurther information for the model application. |
