Aims: As motor vehicle volumes increase around the globe, further pressure is placed on limited financial budgets to fund projects that address traffic congestion on the road networks. This research aims at studying the traffic impact and financial resulted from the traffic congestion on the urban road networks. Study Design: Through the study of the intersection geometry and control type impact on fuel consumption cost at different levels of service for roads. Place and Duration of Study: Benha Faculty of engineering, Benha university, Egypt. Between November 2013 and Feb 2016. Methodology: The Sidra Intersection program was used to calculate the fuel consumption rate, cost of fuel and total cost of the different intersection geometry. Results: Conclusion some relationships which illustrate the effect of the intersection geometry and control type impact on fuel consumption cost at different levels of service for roads. Conclusion: We can decrease the fuel consumption rate, cost of fuel and total cost at different number of lanes due to various of intersection control type by improving levels of service for roads from F to A.
