Abstract

Transportation problem is one of the problems that is faced in Tasikmalaya City especially at the intersection. Congestion problems and traffic conflicts often occur at a signal especially in intersection on Siliwangi road Tasikmalaya. One of the efforts made to reduce traffic conflicts and optimize the performance of the junction is by setting up the junction and optimizing the Simpang. The purpose of this research is to know the performance of intersection on Siliwangi road Tasikmalaya and provide recommendations for precise handling, as well as analyzing the traffic conflicts that occurred in the junction. The method used in the performance analysis of the junction signal is to use the calculations in the PKJI 2014, while for analysis of traffic conflicts used to determine the severity of the conflict at the intersection on Siliwangi road Tasikmalaya is using the method Traffic Conflict Technique (TCT). After analysis, the performance in the intersection on Siliwangi road Tasikmalaya Tasikmalaya has approached the critical number of the degree of saturation (DS) of 0.7 with level D. In addition to these problems, there is a traffic conflict crossing as many as 230 events (55%), merging as many as 145 events (35%) and diverging as many as 41 occurrences (10%). With the handling and recommendation of phase setting and cycle time setting, it is proven to suppress and minimize the decline of junction performance level to C level with the value of saturation of 0.58. This will also impact the reduction in the amount of traffic conflicts that occur.Keyword : intersection, traffic conflict, PKJI 2014, phase, cycle time

Abstract

In the planning, design and determination of various transportation system policies, the theory of traffic flow characteristics plays a very important role. To facilitate the application of the theory of traffic characteristics, a mathematical approach is used to analyze the phenomena that occur in the traffic flow. One approach to understanding traffic behavior is to describe it in mathematical and graphical relationships by paying attention to the relationship between speed (S), density (D) and volume (V) of traffic. The purpose of this study was to analyze the characteristics of traffic flow on Jalan KHZ Musthofa which is the primary arterial road connecting vital locations in the City of Tasikmalaya using several mathematical models, namely the greenshield, greenberg and underwood models. This study has an urgency to determine the characteristics of the appropriate traffic flow and closest to the existing conditions in the field so that it can be used as a basis for determining the level of service on a road segment. This is an answer and proof that there is no road segment that has the same traffic flow characteristics even though the environmental conditions are very similar. From the results of data analysis, it can be seen that the traffic characteristics that are most appropriate to the existing conditions in the field based on the analysis of the selected model on the KHZ Musthofa Road Section, namely the Greenshield Model with free flow speed (Sf) = 52,043 km/hour, congestion density that occurs (Dj ) = 70,207 pcu/km and the maximum volume or road capacity (Vmax) = 3,654,088 pcu/hour. The structure of the model of the relationship between velocity (S) and density (D) is S = 50.96 - (0.66)D, for the model of the relationship between volume (V) and density (D) is V = 50.96 D - (0.66) D2, for the model of the relationship between volume (V) and velocity (S), namely V = 77.13 S – (0.66) S2.

Abstract

The high pedestrian activity on the Taman Siswa Road Section raises the potential for traffic accidents given the high volume of traffic and vehicle speeds, especially during peak hour when going to and from school. The purpose of this study was to analyze the need for pedestrian facilities, the Safe School Zone (ZoSS) on the Taman Siswa Road Section, especially in the school area, SD N Sekaran 1, SD N Sekaran 2 and MI Roudlotul Huda. The research method used to determine the need for pedestrian facilities is by surveying traffic volume, vehicle speed, volume and movement of pedestrians which were analyzed based on MKJI 1997 and PV2. From the results of the analysis, the traffic volume is 1,006 smp/hour during peak hours at 06.30-07.30 WIB. With the value of the road capacity analysis of 1,304.331 smp. So that the road service level of 0.771 is obtained, level C with an average speed on the Taman Siswa Road Section of 37.065 km/hour. For the analysis of the need for pedestrian crossing facilities at SD N Sekaran 1, SD N Sekaran 2, and MI Roudlotul Huda it shows a PV2 value = > 2 x 108, which means that in these locations it is recommended to provide pedestrian crossing facilities in the form of zebra crossing with protection. For the facilities needed by pedestrians, it is recommended to provide sidewalks with a width of 3 meters. At all school locations that have carried out the Z test on speed analysis, analysis of pedestrian behavior when crossing, analysis of introductory behavior, it is concluded that the road is not safe. For this reason, it is necessary to need road equipment facilities in the form of a Safe School Zone (ZoSS). The results of this study are expected to be useful for road users, especially pedestrians in the school area, so that when walking along and crossing the road it provides security and safety for pedestrians.
