“…According to [21]- [23], the improved roads most especially the rural roads provide easier access to markets for farmers and these markets are located alongside the main roads where vehicles pass frequently. Thus, motorists and other road users often stop to buy agricultural produce before they continue their journey which sustains the roadside markets.…”

In many developing countries, especially Nigeria, informal sector activities such as roadside trading, hawking as well as roadside squatting has become increasingly prevalent. Although these activities are often seen as survival strategies for the low-income population with no other means of earning a living, nonetheless, they have negative impacts on the environment and traffic flow and can also compromise the safety and security of the traders. This study aims to explore the factors that contribute to the growth of this phenomenon on encroached highways, urban roads, and open spaces, and to examine its effects on both the environment and the traders. Using a narrative review approach, the research analysed relevant books, journals, conference papers, reports, and policy documents extracted from Scopus, Web of Science and Google Scholars databases. The study findings revealed that economic crises and high levels of unemployment in developing countries have led to an increase in street trading and roadside vending. In addition, the lack of effective urban planning and enforcement of development control laws has also played a significant role in the proliferation of these activities on encroached urban roads and green spaces. Consequently, on highways, the absence of organized and standardized Rest and Service Areas (RSA) at regular intervals in developing countries, especially Nigeria, has facilitated the emergence of roadside markets. Furthermore, this situation is compounded by the location of agrarian settlements along the highways. Thus, to address these issues, the research recommends that the government reorganize, integrate, and upscale the activities of street traders, while also improving urban planning and enforcing road right-of-way barriers to protect urban green spaces and conclusively, the introduction of standard RSA at regular intervals along highways would provide motorists with necessary rest and services, discouraging them from stopping indiscriminately on transits, which often leads to the emergence of roadside markets.

“…Expanding the network of roads and highways increases the availability of resources and facilitates the movement of goods and services, leading to increased economic efficiency [1]. Road improvements have been shown to increase individual economic activity and boost regional economic growth by facilitating market access and trade [2]. [3] found that infrastructure development, especially road infrastructure, significantly encourages economic growth.…”

Pavement overload has become a significant concern in Indonesia due to its damaging effects on the pavement system, where most roads use flexible pavements. Meanwhile, overloading is also typical in other developing countries, causing everything from damage to accidents to the detriment of road users and operators. The current problem is that there is no definite knowledge of handling these overloaded vehicles, which has adverse effects. Therefore, this study aims to reveal the impact of losses caused by overloaded vehicles on flexible pavement. This research uses vehicle traffic load data to examine actual conditions in the field, which are converted to axle load values for each vehicle and used to determine pavement condition using the truck factor approach, mechanistic-empirical design, pavement smoothness level, and the impact of overloading due to fuel consumption by vehicles on flexible pavement. The results show that overloaded vehicles harm the flexible pavement. The increase in truck factor values for all vehicles in overloaded vehicles beyond the maximum allowable load results in more damage to the flexible pavement with an increase in truck factor values up to 83 %. The effect of overloading can be mitigated by increasing the thickness of the asphalt layer and the modulus of asphalt, so it is essential to pay attention to the quality of asphalt in anticipation of this overloading. To anticipate the overload phenomenon, it was found that the thickness of the asphalt overlay in the range of 170–205 mm could mitigate this detrimental effect. In addition, overloading affects the flexible pavement roughness and vehicle fuel consumption. Increased roughness and fuel consumption will increase road maintenance costs and affect driving comfort and safety. In addition, excessive fuel consumption can pollute the surrounding environment
