Transportation infrastructure programs need significant investment, as well as financial, technical, as well as economic rationales. Reliance and rational techniques (for example, cost-benefit assessments and multi-factor appraisals) are increasingly employed to compare and contrast the merits and demerits of transportation programs and identify funding priorities. Transport economics predominantly entails issues associated with transport systems economics, including environmental impacts of the transport infrastructures, the role of economic theory in augmenting transport logistics, and the funding of transport systems projects. Contemporary transport is anchored on a significant supply of rails, roads, ports, bridges, and air control infrastructures. The modernity and intensity of the current transport systems have culminated in the growth of the field of transport economics, which incorporates issues related to building new systems or repairing existing ones. The associated costs impact the discipline of transport economics, and such themes significantly influence new discourses about the price and financing of such projects. Social costs play a central role in transport economics. It is crucial to recognize that social costs enhance different transport projects. Consequently, this culminates in positive ramifications on the country’s economic progress goals, including alleviating unemployment and promoting productivity, commercial activities, property value appreciation, investment, and taxation revenues.
Social costs in transport help ensure that there is feasible care to mitigate the impact of double-counting that could have been accounted for in travel time and vehicle cost savings, in addition to the emission and safety benefits. Nevertheless, it is important to consider the impact of the wide-ranging benefits of social costs on transport system economic ramifications, both positive and negative. For example, the scaling up of the urban highway might have the potential to augment the ability of motorists to access the infrastructure and mitigate the potential for vehicle-mile costs. Consequently, this substantially contributes to reducing the hurdles to pedestrian movement and augmenting increased utilization of dispersed land masses for development trends by reducing access via other models. This also increases the funds spent traveling to different destinations (Sandow, 2019). Simultaneously, social costs improve access to specific areas, thus exposing enterprises to valuable and competitive customer segments. This includes allowing local customers to access global retailers easily by easing their movement.
Social costs also impact the value of transport systems. They account for a substantial share of the total costs of transport systems. The aggregate price of any commercial enterprise incorporates the cost of externalities. The computation of complete expenses for the specific transport system remains relevant in transport economic theory for utilization of program analysis as well as execution, particular because transport constitutes a public service. The social costs are increasingly significant and real in the community and are therefore, incorporated in computing compete expenses employed to appraise and develop policies, thus authenticating their value in transport economic theory. In addition, social costs are important in establishing the approach to mitigate them and their ramifications in the economy. Social costs negatively impact the country and the magnitude of complexities that contribute to burgeoning costs in the long-term (Stern & Stiglitz, 2021). For example, traffic congestion contributes to high fuel consumption which escalates the consumption costs.
