| Summary: | The purpose of this paper is to explain the most appropriate approaches for traffic modeling in vehicle routing problem based on green transportation paradigm. There are four approaches in literature for modeling of traffic including: simple, discrete, continuous, and random. Based on the qualitative meta-analysis method, 67 sources of green transportation were examined descriptively (in terms of using the above-mentioned approaches based on descriptive statistics) and evaluating (assessing the strengths and weaknesses of the approaches), which resulted in It was better to use a continuous approach. Regarding the existence of different patterns of modeling in the continuous approach, in order to achieve the appropriate model, Zamzam's distribution network was used based on Tehran Pars sales data on 21 August 2016. The results showed that existing patterns were inappropriate and that a proper pattern for the Zamzam distribution network should be developed. The developed pattern consists of two indicators: 1) the definition of the virtual node; and 2) the calculation of the average speed, taking into account multiple traffic conditions. This pattern corrects the weaknesses of previous patterns based on continuous approach. |
