Background and Objective: In order to investigate the effect of electric L-category vehicles (EL-Vs) on traffic characteristics of urban roads, fuel consumption and exhaust emissions, existing technologies including traffic characteristics, vehicle performance were used. Methods: The relations among traffic density, traffic flow, and traffic speeds were reviewed based on the real test data in different areas. Results: One of the test data was chosen to get the mathematical equations between traffic density and traffic speed for congested urban roads. Conclusion: Then, the equations were used to estimate the reductions of vehicle fuel consumption and exhaust emissions brought by the improved traffic situation due to the applications of ELVs.
