Urban freight transport is essential for supporting our society regarding providing the daily needs of consumers and local businesses. In addition, it allows for the movement of goods, is distributed within urban environments, provides thousands of jobs, and supports economic growth. However, a number of issues are associated with urban freight transport, including environmental impacts, road congestion, and land use of freight facilities that conflicts with residential land use. Electric freight vehicles create zero emissions and provide a sustainable delivery system in comparison with conventional freight vehicles. In this study, a novel dynamic inventory routing and pricing problem under a mixed fleet of electric and conventional vehicles was formulated to minimize the total travel and charging costs. The proposed model is capable of deciding on replenishment times and amounts and vehicle routes. We aimed to determine the maximum social welfare (SW) capable of providing an optimal trade-off between the supplier cost and customer delay that uses a mixed fleet of vehicles. Our computational study was conducted on real data generated from a delivery dataset in Tehran. Under the proposed policy with a fleet of only electric vehicles, the SW increased by 3% while the average customer delay reduced by 15% compared with a fleet of conventional vehicles. The results show that the number of served customers and customer delay would be affected by transitioning conventional urban freight vehicles to electric vehicles. Therefore, the proposed delivery system has a significant impact on energy savings and emissions.

Urban Freight Transport

The high costs of using electric vehicles (EVs) is hindering wide-spread adoption of an EV-centric decarbonisation strategy for urban freight transport. Four opportunity charging (OC) strategies—during breaks and shift changes, during loading activity, during unloading activity, or while driving on highways—are evaluated towards reducing EV costs. The study investigates the effect of OC on the lifecycle costs and carbon dioxide emissions of four cases of different urban freight transport operations. Using a parametric vehicle model, the weight and battery capacity of operationally suitable fleets were calculated for ten scenarios (i.e., one diesel vehicle scenario, two EV scenarios without OC, and seven EV scenarios with four OC strategies and two charging technology types). A linearized energy consumption model sensitive to vehicle load was used to calculate the fuel and energy used by fleets for the transport operations. OC was found to significantly reduce lifecycle costs, and without any strong negative influence on carbon dioxide emissions. Other strong influences on lifecycle costs are the use of inductive technology, extension of service lifetime, and reduction of battery price. Other strong influences on carbon dioxide emissions are the use of inductive technology and the emissions factors of electricity production.

In an effort to monitor and control the urban freight transport, the Municipal Government of Surakarta City issue a dispensation license for freight vehicles through the inner-city road. Nevertheless, the facts indicate that traffic violations by freight vehicles against the provisions of existing regulations are relatively high and thus have the potential to decrease the level of safety, road service and environmental sustainability. This is due to the weakness of the system of monitoring and the control of urban freight transport is low both in terms of technicality and legality. The research’s aims are to evaluate and improve the current system of monitoring and control of urban freight transport related to the provision of the dispensation license for freight vehicles through the inner-city road in Surakarta City. The analysis results indicate that the percentage of unlicensed urban freight transport is significant in number, and no clarity is associated with licensing dispensation for urban freight transport weighing > 9,000 kg, a significant number of traffic violations, road bearing capacity of freight transport routes do not correspond to the vehicle weight. Various recommendations are proposed for improving the current system of monitoring and of the control of urban freight transport.

Various research efforts are undertaken to reduce the ill-effects of urban freight transport on the city’s environment. Replacing conventional freight vehicles with electric commercial vehicles (ECVs) is considered as the most effective solution; however, this transition is facing several technological and infrastructural challenges. In developing countries, where cities are already struggling to manage with their present infrastructure, they would find it even more difficult. This paper highlights the opportunity for sharing of in-use freight vehicles as an immediate solution to reduce vehicular emissions. Case study of Surat city, India is taken to assess the use of small-sized commercial vehicles for urban freight transport. A detailed study has been carried out to determine the extent of under-utilized or unutilized capacities of these vehicles. Reductions in emissions due to the sharing of trips are estimated. Propositions are made to strategize and develop policies that promote sharing of urban freight trips.

The aim of this paper is to analyze the perceptions of the transport service providers on the barriers in urban freight transport and the restrictions imposed on freight vehicles, identifying which urban freight transport policies can improve this activity in Brazil. Principal component analysis allowed us to identify which are barriers in urban cargo transport and the restrictions imposed on freight vehicles. In addition, we evaluated freight policies that can improve the activity using probabilistic preference. We obtained the database from a web-based survey of transport service providers in Brazil. The results indicate that the urban freight vehicle restriction is related to congestion and availability of loading and unloading areas. The freight vehicle restriction is a result of the lack of information and data. The theft of cargo significantly impacts urban freight transport. Transport service provider company perceptions indicate an urban mobility plan as the most-required freight policy to improve freight mobility. To reduce the barriers to urban freight planning, an understanding of the problem involving the stakeholders is needed. To do so, the challenge is to change the culture in the transportation planning process by integrating various actors to create an urban logistics plan that generates opportunities for the city.
