This study analyzes the design of the width and rigid pavement of the road on Sp. Brongkos – Ngembul, Kesamben District, Blitar Regency, along 4.5 km with an existing road width of 5 meters, rumija 16.8 meters. The surrounding area includes forestry, residential, plantation, industrial, and Jolosutro Beach tourist access, with increased traffic density during the holiday season and industrial operations. The method used is descriptive quantitative based on LHR and CBR data. The calculation of lane width using MKJI 1997 (Indonesian Road Capacity Manual) shows the need for widening of 3 meters per lane and 2 meters of shoulder. The rigid pavement design using the MDPJ 2024 method (Road Pavement Design Manual) consists of a layer of coarse-grained soil embankment, class A aggregate, lean concrete, and structural concrete with a thickness of 200 mm, 200 mm, 150 mm, and 200 mm, respectively. With the JPCP design, for the tie bar connection reinforcement with a diameter of 16 mm, a length of 700 mm, a distance of 70 cm, and a dowel with a diameter of 28 mm, a length of 45 cm, and a distance of 30 cm.

The growth in the number of vehicles in Surabaya has led to increased traffic congestion, particularly on the Perak Timur–Perak Barat road section, which serves as a major distribution route to the port and industrial areas. Problems arise at U-Turn points, where vehicle accumulation hampers traffic flow. This study analyzes traffic volume, travel time, queue length, and queue ratio at two U-Turn points on this section. The method used was a field survey with direct observation of vehicle volume every 15 minutes, vehicle classification, and queue length. Traffic volume was calculated using the Passenger Car Equivalent (PCE) factor based on the 1997 MKJI standards. The study results show that at Point 1, east–west direction, the highest queue ratio occurred on Tuesday from 11:00 to 12:00 (p = 4.84), while the lowest was on Sunday from 06:00 to 07:00 (p = 0.21). At Point 2, west–east direction, the highest queue ratio occurred on Tuesday from 08:00 to 09:00 (p = 6.18), and the lowest from 06:00 to 07:00 (p = 0.41). These findings indicate that during peak hours, traffic congestion increases (p > 1), causing long queues, particularly in the west–east direction in the morning. The performance of the U-Turn on the Perak Timur–Perak Barat road section needs improvement, with recommendations such as temporarily closing U-Turns during high volumes, providing alternative U-Turn lanes, and adding signs to minimize the potential for vehicle conflicts.

Unsignalized intersections are a major point of concern due to the increasing number of vehicles. Bima City is a city located on the eastern part of Sumbawa Island, West Nusa Tenggara Province. As a developing city, congestion and busy traffic often occur on roads or intersections of Mongosidi and Anggrek roads. Therefore, this study was conducted to determine the performance and level of service of unsignalized intersections at Mongosidi Street and Anggrek Street. The method used refers to the Indonesian Road Capacity Manual (MKJI) 1997. This study aims to determine the indicators of traffic behavior at unsignalized intersections.

Penelitian ini bertujuan untuk mengetahui pengaruh penyempitan jalan terhadap karakteristik lalu lintas jalan pada halte bus BRT depan Pasar Jatingaleh Semarang. Pergerakan masyarakat yang terjadi di Kota Semarang semakin meningkat seiring dengan perkembangan yang ada hingga menyebabkan meningkatnya arus lalu lintas. Salah satunya permasalahan yang mempengaruhi kondisi lalu lintas yaitu adanya penyempitan jalan, seperti pada jalan Teuku Umar tepatnya di halte bus BRT depan Pasar Jatingaleh Semarang. Pada lokasi tersebut sering terjadi kemacetan lalu lintas sehingga menyebabkan antrian panjang terutama pada jam-jam tertentu. Data diambil langsung dari lapangan meliputi volume, kecepatan, dan kepadatan lalu lintas. Analisis data didasarkan pada Manual Kapasitas Jalan Indonesia (MKJI) 1997 dengan menggunakan perangkat lunak Microsoft Excel. Adapun analisa hubungan karakteristik lalu lintas pada penyempitan jalan di ruas jalan Teuku Umar menggunakan model Greenshield. Dari hasil analisis diketahui bahwa kecepatan maksimum, volume puncak, kepadatan maksimum, kapasitas jalan, dan derajat jenuh atau degree of saturation diketahui dengan melakukan survey lapangan.

Jalan merupakan fakor penting bagi perkembangan kehidupan manusia karena perkembangan jalan dan perkembangan kehidupan manusia saling mempengaruhi meningkatnya kemacetan pada jalan. Diakibatkan bertambahnya kepemilikan kendaraan pribadi, terbatasnya sumber daya untuk pembangunan dan belum optimalnya pengoperasian fasilitas arus lalu lintas yang ada. Pada ruas Jl. Raya Pekajangan tepatnya di simpang 4 Pasar Ngebrak Bligo – Pekalongan, perjalanan terbanyak umumnya terjadi pada sore hari dimana banyak orang melakukan pergerakan serentak di waktu yang sama dan menyebabkan kemacetan. Tujuan dari analisa ini adalah untuk mengetahui penyebab dan dampak kemacetan lalu-lintas di simpang 4 Pasar Ngebrak Bligo sehingga bisa diberi solusi untuk mengatasi permasalahan tersebut. Setelah diperoleh data volume lalu lintas, dilakukan analisa lalu-lintas berdasar aspek teknis yang didasarkan pada pedoman Manual Kapasitas Jalan Indonesia (MKJI, 1997) untuk menentukan kapasitas, volume lalu-lintas, kecepatan arus bebas, derajat kejenuhan dan tundaan. Oleh karena itu peraturan lalu-lintas oleh dinas terkait sangat penting demi menciptakan keteraturan lalu-lintas.

Economic activity becomes a benchmark in the assessment of the community to achieve prosperity, and becomes a supporter and driver of growth in the surrounding area. Vim Village, Abepura District is one of the service activity centers that has a land use that is so complex and strategically located that it triggers various forms of economic activity, becoming an attraction for people to travel for transportation, especially along Jalan Perkutut. This study examines the relationship of micro-economic activities with traffic performance obtained from side barriers, vehicle volume and road capacity. The research methods used to achieve the objectives are quantitative methods and qualitative methods. The quantitative method uses the analysis of the Indonesian Road Capacity Manual (MKJI, 1997) to obtain vehicle volume, road capacity and traffic performance. The qualitative method uses descriptive analysis that discusses the comparison of the distribution of micro-economic activities that affect side barriers, the comparison of two traffic performance results and spatial planning plans along the Perkutut road. The results showed that the increase in the number of micro-economic activities at night along Jalan Perkutut had an effect on increasing the number of side barriers and the volume of vehicles. In addition, the imbalance in the volume of vehicles and road capacity shows that Perkutut Road traffic performance is experiencing congestion as indicated by the Service Level Index (ITP) with a value of F. Under these conditions, spatial planning for the road network, pedestrian pedestrian arrangement and land use arrangement is needed, especially on microeconomic activities.
