The urban transportation system needed is a transportation system that can facilitate people’s mobility and/or goods to go in and out of urban areas as well as serve community activities in their own cities. The analysis of the road congestion causes in the city center of Bandar Lampung, especially Jalan Raden Intan Tanjung Karang Bandar Lampung will carry out good traffic flow planning in accordance with the wishes of the community by looking at the impact of vehicle performance on peak hours when density covers roads and identify traffic on Jalan Raden Intan Bandar Lampung. Based on the results of the analysis that has been carried out, it can be concluded that the percentage comparison between continuous flows and sampling barriers that affect the surrounding, among other vehicles exiting and/or entering on weekdays is 12% and weekend ratio is 13.8%.

Introduction Traffic congestion is caused by an imbalance between the increase of vehicle ownership and the growth of available road infrastructure and effective capacity of existing road segments which are smaller than the planned road capacity due to roadside obstacles. Roadside barriers are often associated with social and economic activities, namely on-street parking, because there are shops on the road, public transportation facilities that drop passengers in any place and people crossing the street which cause road capacity to decrease. In line with this, transportation activities on Jl. Raden Intan Bandar Lampung are also increasing. This street is one of the roads that is quite heavy in traffic. When many sellers and buyers, as well as vehicles pass or stop to park on these roads, it will really disturb the flow of the traffic. Roads that are supposed to be used for traffic are now seized for parking. In addition, there are many street vendors who sell on the pedestrian sidewalk, and a lot of access in and out of the store along the road. Especially on Jalan Raden Intan Bandar Lampung. The highest number of trips generally occurs in the morning and in the evening when many people carry out activities at like going to school or to their work place and vice versa. In general, everyone wants to arrive at his/her destination on time in the morning. However, the result of the trips that are simultaneously carried out, there is a heavy flow of traffic. Therefore, the writer wants to analyze what causes the congestion. Munawar (2011) argues that to determine the optimal points that cause congestion is by dividing them into several segments to find out the distance (s) and time (t). Congestion can be due to the irregularity of the vehicle traffic; therefore, a traffic lane arrangement such as roads, traffic regulations from related parties regarding vehicles, optimization of good crossing bridges by the community is needed, so that everything can go well. A good traffic management will provide security, comfort and ease of pedestrians’ mobility, bicycles, motorists, cars and other modes of public transportation. The influence of these side barriers also occurs on national roads. National road itself is a system of primary road networks that connect between provincial capitals. Thus, the required road segment should be in accordance with the existing road section without being disturbed by side obstacles. For instance, Jalan Raden Intan segment to Tugu Adipura which has been designated as a national non-toll road network. On the contrary, in fact, the side resistance level actually makes the road segment not maximally used with the road conditions that do not change. 2. Research Methods According to Tamin (2008) research related to road performance is divided into 4 stages, namely planning, preparation, implementation, and data processing. a. Planning To get data that support the survey, the criteria can be divided into the types of surveys, technically the data obtained must be appropriate (can measure the desired variable) and with high validity. Economically the survey
