“…Dalam penelitian ini, konsep CarPooling diimplementasikan dengan menggunakan moda transportasi motor dengan pertimbangan bahwa presentase kendaraan terbanyak di Universitas Muhammadiyah Surabaya adalah pengguna motor. Selain itu, biaya motor per mil dengan kapasitas rerata 1,27 pax lebih rendah sekitar 50% jika dibandingkan dengan biaya mobil per mil dengan kapasitas rerata 1,57 pax [23].…”

Kemacetan lalu lintas mengakibatkan dampak sosial ekonomi, dampak psikis, serta dampak lingkungan. Salah satu solusi untuk menangani kemacetan adalah peningkatan okupansi kendaraan pribadi. Dalam penelitian ini dilakukan studi kasus pada lingkup Universitas Muhammadiyah Surabaya yang memiliki jumlah mahasiswa banyak namun jalan sekitar kampus yang relatif sempit sehingga berpotensi terjadi kemacetan. Berdasarkan hasil observasi, jumlah mahasiswa pengguna motor di kampus tersebut sangat banyak namun sangat jarang yang membawa 2 penumpang. Sehingga penelitian ini berfokus untuk mengembangkan sebuah aplikasi berbasis android yang mengajak mahasiswa agar memaksimalkan okupansi motor mereka. Kata kunci:kemacetan, okupansi motor, perangkat lunak, android.

The car is a main means of transportation all over the world. However, many people drive a car when they travel a short distance alone, that is inefficient in cost and space. Then, personal mobility vehicle (PMV), which is one or two-seater and has high environmental performance, is recently gathering attention. We focus on the three-wheeled vehicle with leaning mechanism called Narrow Tilting Vehicle (NTV) or narrow tilting three-wheeled (NTTW). Leaning mechanism, which gives tires degree of freedom, has an effect of stable cornering in the case of short tread width vehicle. To compere the motion of each leaning mechanism, we model the two types of NTV. One has two front frame which are linked to vehicle body by the arm and rotating respectively around the joint. The other one has a front frame that has two tires connected by the link. We derived equation of motion by referring to Sharp's 4 DOF two-wheeled vehicle model, and carried out the three kinds of numerical analysis, eigenvalue analysis, modal analysis and running simulation. Through eigenvalue and modal analysis, we find out that NTVs have the same modes as Sharp's 4 DOF model does, and they have the characteristic mode which vibrates steering and leaning mechanism. By running simulation, NTVs required larger steering torque than two-wheeled vehicle when the vehicle turn at the same angle.

“…As global populations continue to surge alongside rapid economic development, demand for automobiles is increasing, and transportation problems such as lack of parking spaces and air pollution are also increasing. In response to this, there has been a heightened focus on compact vehicles as a potential solution to mitigate the challenges associated with increased vehicular density [1,2]. However, because compact vehicles are generally narrow, the potential risk of vehicle rollover is greater than that of regular vehicles.…”

The automotive industries currently face challenges such as emission limits, traffic congestion, and limited parking, which have prompted shifts in consumer preferences and modern passenger vehicle requirements towards compact vehicles. However, given the inherent limited width of compact vehicles, the potential risk of vehicle rollover is greater than that of regular vehicles. This paper addresses the safety concerns associated with vehicle rollover, focusing on narrow tilting vehicles (NTVs). Quantifying stability involves numerical indicators such as the lateral load transfer ratio (LTR). Additionally, a unique approach is taken by applying ZMP (zero moment point), commonly used in the robotics field, as an indicator of vehicle stability. Effective roll control requires a detailed analysis of the vehicle’s characteristic model and the derivation of lateral and roll dynamics. The paper presents the detailed roll dynamics of an NTV with a MacPherson strut-type suspension. A stability-enhancing method is proposed using a cascade structure based on the internal robust position controller and outer roll stability controller, addressing challenges posed by disturbances. Experimental verification using Simscape Multibody and CarSim validates the dynamic model and controller’s effectiveness, ensuring the reliability of the proposed tilting control for NTVs in practical scenarios.
