【正文】 icate that the revenue from road pricing plays a crucial role. If the revenue is recycle to permit investment in public transport, or maintenance of higher service levels, it helps to provide a clear alternative, which both reinforces the impact on mode choice and reduces the concern of those on whom the charge is imposed. If it is used to improve the road infrastructure, it can be seen that traffic diverted from the controlled area is being catered for. If it is used to pay for environmental improvements, it will help to reinforce the wider benefits of charging. How to use the revenue and improve the efficiency of urban transport system is play a key role in sustainable development. 5. Conclusions With the continuing growth in traffic demand and decreasing scope for expansion of road infrastructure, traffic congestion is not a problem that will go away soon. Congestion pricing is proposed as an important demand management strategy for tackling traffic, but still receives strong social and political opposition because of the uncertain impacts on economic development, environmental protection and social justice. This paper reviews the relationship between congestion pricing and three goals of sustainable transportation system, and the results show that congestion pricing is a promising traffic management strategy, which can promote urban economic development, improve environmental quality and reduce inequity. Recent advances in electronic toll collection (ETC) technologies have made congestion pricing technologically feasible. It is safe to predict that ing decades will witness an increasing number of implement or attempts to implement congestion pricing. The design and evaluation of congestion pricing will require a deeper understanding of the direct and indirect impacts on sustainable development.

Appreciation is also extended to reviewers for their helpful ments and suggestions on improving this paper. 。 up till now, it is the most wellknown example of a large metropolitan area that has implemented congestion pricing. However, congestion pricing has not seen widespread use in practice due to theoretical and political reasons. Some potential impacts of road pricing remain unknown, and the sustainability of congestion pricing for urban development requires further study. Sustainability is normally taken as basic objectives in the assessment of transportation policy. The idea of sustainable transportation emerges from the concept of sustainable development in the transport sector and can be defined as follows ，“sustainable transportation infrastructure and travel policies that serve multiple goals of economic development, environment stewardship and social equity, have the objective to optimize the use of transportation systems to achieve economic and related social and environment goals, without sacrificing the ability of future generations to achieve the same goals”. Sustainable transportation systems require a dynamic balance between the main pillars of sustainable development, economic development, environmental protection and social justice for current and future generations. In the context of sustainable transport systems, how congestion pricing can contribute to economic growth, environmental protection and social justice is examined in this paper. The rest of the paper is structured as follows. In section 2, the impacts of congestion pricing on economic development are described. Section 3 presents the contribution to environment protection, and the relationship between social justice andcongestion pricing is analyzed. Some conclusions are given in section 5. 2. Economic development Traffic congestion, resulting in the increase of travel time, traffic accident, energy consumption and environment deterioration, has produced numerous economic losses. It was reported that economic loss caused by traffic congestion amounted to 40 million Yuan per year in Beijing and 1/3 of GDP in Shanghai in 2021 In many cites, traffic congesti
