Research trends related to road innovation in civil construction of public spaces

Road innovation is transforming civil construction by introducing technologies and approaches that improve the efficiency, safety and sustainability of transportation infrastructure. These traffic management systems and real-time monitoring sensors optimize vehicular flow and minimize congestion. The objective of the research is to analyze research trends related to road innovation in civil construction of public spaces. The research approach is mixed, combining qualitative and quantitative methods. A descriptive and retrospective bibliometric analysis was carried out, which was complemented with a documentary review, developed in the Google academic database, Scielo and SCOPUS. The behavior of the researches was decreasing, characterized by a polynomial function with a maximum peak in 2020 of 27 researches. Research in environmental sciences in China predominated. Three lines of scientific research and their main thematic nuclei were identified and explored as key categories and systematized in order to recognize the trends of road innovation in the civil construction of public spaces. The main results were introduced in China with analysis of impacts on the population, use of geographic information systems, environmental pollution studies, among others. Despite international efforts to develop sustainable strategies for the construction and management of public spaces, there are still significant challenges to be addressed to ensure innovation and sustainability in this area.
