| Author | Jen-Jia Lin, Yu-Sheng Shen |
| Summary | The Local Street System denotes the network of collectors and alleys in a block bounded by arterials. This research aims at the analysis model for the spacing design of Local Street System. The model was designed as a multi- objective grey integer programming model, in which three objectives, i.e., accessibility, mobility, and traffic safety, are considered. The constraints included travel demand, emergency services, public refuge, noise, air quality, and minimum width, and depth of architectural base. Since the planning tasks are filled with uncertainties, the parameters and decision variables of model were both designed as grey numbers, which represented the possible ranges other than crisp values. Additionally, this research developed the approach of Grey Integer TOPSIS for solving the developed model, and this approach can also be applied to solve the other multi-objective grey integer programming models. A mixed-use block in Dan-Hai New Town was investigated as a case study to justify the applicability of model. We also analyzed the influences of traffic calming measures and parameters’ grey degree on spacing design to identify the model’s characteristics. The results of this case study provided further information for the model application. |
