Side frictions along the market area of Tanjungsari often cause traffic congestion during peak hours. The traffic congestions are caused by the high frequency of side frictions decreasing the effectivity of road capacity value. This paper analyse the degree of saturation due to side frictions influencing on traffic congestion as well as providing some effective alternative solutions. The traffic congestion analysis method refers to the PKJI 2014 by considering the level of service standard. The three alternative solutions are simulated by the detouring and widening road as well as combining those alternatives. The solutions are concerned with the level of service standard for 10 years period. The analysis results shows that the most effective alternative solution is a combining solution between road widening and detouring. The other result shows that detour could solve congestion if the width of alternative road equals to the width of previous main road.The result of combining alternative shows that the level of service may achieve the category of "C" complying to the rural road standards. The degree of saturation Bandung-Sumedang segment is 0.51, whereas Sumedang-Bandung segment is 0.74. These solution achieve upto 57% reduction of traffic congestion Bandung-Sumedang section and 52% Sumedang-Bandung section.
