Abstract
Cities are locations with high level of accumulation and concentration of economic activities. They are complex spatial structures supported by transportation systems. Nowadays, urban transportation is considered as an important subject in urban planning. It consists of passenger and freight transportation. Congestion is one of the most prevalent transport problems in large urban agglomerations. Pollution, including emissions, generated by different types of vehicles has become a serious impediment to the quality of life and even the health of urban populations. In this work, we develop a bi-objective sustainable optimization model with congestion constraint. Two objective functions in this model includes: minimizing freight and passenger transportation cost and CO emission. In this model, we consider freight and passenger transportation together as a new challenging framework in urban transportation area which has not considered before. We solve our model with constraint method in order to obtain Pareto points. We consider cost function as our objective function and put CO emission function in constraints. At last, we compare the results of proposed integrated model with the results of separate passenger and freight transportation models. We check if there is any improvement in value of objective functions.
