Routing Optimization of City Distribution Considering Access Restriction

Nowadays, urban freight transport has become one of the most significant contributors to congestion and pollution. To combat these negative impacts, local authorities implement some restrictive regulations imposed on logistic enterprises about the time and area to which their vehicles can access. Under this circumstance, this paper constructed a city distribution routing optimization model considering access restriction. A Genetic Algorithm was proposed to solve the model. Numerical experiments based on the Solomons benchmark problems proved the effectiveness of the proposed model and algorithms.
