Abstract

The Covid-19 virus causes a decrease in the activity of transportation movements on the R.A. Kartini. As a result of the decrease in transportation movement, it can have a positive effect, namely the reduction of traffic jams on Jalan RA Kartini. In connection with the above problems, it is necessary to study the road performance of R.A. Kartini during the new normal period which can then be compared with the road performance of R.A. Kartini during normal times, in order to find out how much changes in traffic performance on R.A. Kartini due to Covid-19. Thus, this study aims to determine the road performance of R.A. Kartini in new normal condition and normal condition. The results of this study indicate that there has been a change in the level of road services on Jalan R.A. Kartini with road service level during normal condition class D becomes class B road service level when new normal condition.Key words: Road Performance, Degree of Saturation, Traffic Volume, Capacity.

Abstract

Pangeran Antasari St. is a road with a high level of congestion, especially during peak hours. This of course causes cumulation of vehicles which will making queues of vehicles. The congestion and density have caused a lot of shockwaves phenomena in the traffic around Pangeran Antasari St. This study examines the shockwaves in the trip delay which are influenced by the U-turn. The data was collected at Pangeran Antasari St. on October 5, 2020 during 06.00-09.00 am and 15.00-18.00 pm. The types of vehicles observed were Motorcycle (MC), Light Vehicle (LV), and Heavy Vehicle (HV).The shockwaves value obtained using the Greenshield Method of Pangeran Antasari St. at the morning section obtained the shockwaves value with the value of the reverse shockwaves (ωab) = -2284.98 km/h, the reverse shockwaves recovery (ωcb) = -16.2602 km/h, shockwaves forward recovery (ωac) = 55.707 km/h. At the afternoon, the shockwaves value is obtained with the value (ωab) = 3,3706 km/h; reverse shock wave recovery (ωcb) = -10.0224 km/h; forward shock wave recovery (ωac) 5.6654 km/h. The queue length (Qm) that occurs is 0.05 km or 53 m with a normalizing time (T) of 20.4279 seconds.

Abstract

AbstractSide Obstacles that occur on Jalan Untung Suropati to be precise in the market area of Labuhan Ratu Station such as the use of the shoulder of the road as a parking lot, the road used by pedestrians, vehicles entering and leaving the market, loading and unloading of goods carried out on the road, as well as vehicles used by pedestrians. stop to go up and down. The railroad crossing adjacent to the market will affect traffic flow, and the entry and exit of vehicles on the train will cause side barriers. This study aims to determine how much influence the side barriers that occur and how these obstacles affect vehicle speed on Jalan Untung Suropati Labuhan Ratu. Side drag, speed and volume of direct traffic data by conducting a survey for 1 day and analyzed using the 2014 Indonesian Road Capacity Guidelines, while the effect of side barriers on speed was analyzed using linear regression with the help of Microsoft Excel. From this study, it was found that the highest volume on Monday afternoon at 17.15-17.20 WIB was 793, the highest speed on Monday afternoon was 16,422 km/hour, the highest side drag on Monday morning was 138.4. Based on the results of linear regression analysis, it can be seen that the side resistance is negative, this indicates that if the resistance variable increases by 1, it will affect the speed of 0.0464.  Keywords : Side barrier; speed, traffic flow.AbstrakHambatan Samping yang terjadi di ruas Jalan Untung Suropati Tepatnya di kawasan pasar Stasiun Labuhan Ratu seperti penggunaan bahu jalan sebagai tempat parkir, badan jalan yang digunakan oleh pejalan kaki, kendaraan yang masuk keluar pasar, bongkar muat barang yang dilakukan di badan jalan, serta kendaraan yang berhenti untuk menaik dan menurunkan. Palang kereta api yang berdekatan dengan pasar akan mempengaruhi arus lalu lintas, serta keluar masuknya kendaraan di kereta api kereta api akan menimbulkan hambatan samping. Penelitian ini bertujuan untuk mengetahui seberapa besar pengaruh hambatan samping yang terjadi serta bagaimana pengaruh hambatan tersebut terhadap kecepatan kendaraan di Jalan Untung Suropati Labuhan Ratu. Data Hambatan Samping, kecepatan dan volume lalu lintas langsung dengan melakukan survei selama 1 hari dan dianalisis dengan menggunakan Pedoman Kapasitas Jalan Indonesia 2014, sedangkan untuk pengaruh hambatan samping dan arus lintas terhadap kecepatan dianalisis menggunakan regresi linier dengan bantuan Microsoft Excel. Dari penelitian ini didapat volume tertinggi pada senin sore pukul 17.15-17.20 WIB sebesar 793, kecepatan tertinggi pada senin sore sebesar 16.422 km/jam, hambatan samping tertinggi pada senin pagi sebesar 138,4. Berdasarkan hasil analisis regresi linier dapat diketahui bahwa hambatan samping bernilai negatif, hal ini menunjukkan bahwa jika variabel hambatan mengalami peningkatan 1 , maka akan mempengaruhi kecepatan sebesar 0,0464.Kata kunci : Arus lalu lintas; hambatan samping, kecepatan.
