Abstract: In this paper, an urban road design concept is proposed that introduces gentle slopes along straight roads to optimize fuel efficiency between signalized intersections. These calculated inclines leverage gravitational forces, reducing vehicle fuel consumption. At signal crossings, a deliberate reversal of slope mitigates depth accumulation concerns, promoting safe intersection navigation. Smooth transition zones enhance road stability and drain depth adjustments accommodate stormwater management. Collaborative efforts with experts and public awareness initiatives are vital for successful implementation. This innovative concept combines technical precision, safety considerations, and environmental sustainability, offering a holistic approach to urban road design for enhanced efficiency and user experience.
