“…The transportation system is a form of interrelatedness between actors within its scope, such as users, goods, infrastructure and facilities, both natural and planned. This system means coordinating movement with components that use media in measurable transportation processes (Li et al, 2017;Mampearcachchi, and Masakorala, 2018;Rymarz et al, 2015;Stogios, 2018).…”

Traffic in the city of Bogor is relatively high. With this level of density, the city of Bogor is classified as the second most congested city after DKI Jakarta. Achieving the process of transporting passengers and goods as optimally as possible in a certain space and time taking into account several factors such as safety, comfort, smoothness, time efficiency and costs according to these needs. The balance and needs of transportation facilities and infrastructure in achieving its goals is the real movement of each user. The main objective of this study is to formulate a model for the sustainability of transportation facilities and infrastructure in the management of public transport with the concept of inter-regional cooperation. The originality/novelty in the research is a) the handling of the model of sustainability of transportation facilities and public transport transportation infrastructure in the two regions of Bogor regency and Bogor city, b) the sustainability of the public transport management model with the concept of inter-regional cooperation, namely Bogor regency and Bogor city in reducing congestion between the two buffer city. The methods used are survey methods, interviews and studies of expert opinions. This concept is called MODEL SUSTAIN-SARPRASKOKABO_2023. By referring to this initial concept, it is hoped that a balanced and sustainable traffic pattern in Indonesia will soon be realized.

“…At any time of travelling, relative distance and speed must be measured and analysed. Mampearachchi et al, (2018) proposed a safe overtaking manoeuvre on two-lane highways, with a number of models. None of the preceding researches in the literature covered the movement of an autonomous vehicle in a longer period of time, which included various types of maneuvers, including cruise control; lane change and overtaking.…”

This paper describes trajectory planning for an Autonomous Vehicle (AV) in the freeway path. Three types of driving modes are analyzed. First was free flow, this constitutes that moving at the desired speed is determined at the beginning of the movement. Second case was car following, when overtaking or lane-change was impossible, distance or speed adaptation is executed using the variable acceleration/deceleration strategy. Third case was lane change or overtaking. For lane change or overtaking paths, the 5th degree polynomial is used to create a curvilinear path to changes its path to the left lane and then returns to its default lane. The velocity and relative distances of cars are main factors for decision making. All proper driving decisions algorithm is introduced. According to autonomous car desired velocity, in the two driving cases (fast and slow desired velocity for AV) are studied by simulation and their results analyzed and compared with together.

Three-Dimensional Stopping Sight Distance Calculation Method under High Slope Restraint

et al. 2020

Sight distance is an important indicator to ensure the safety of drivers, and is also an indispensable evaluation basis in highway safety engineering. In mountainous highways, high slopes and small radius often lead to poor visibility and traffic accidents. Through the combined calculation of horizontal and vertical sections, this paper comprehensively considers the specific sizes of roadside clearance, high slope, as well as the position and height of the driver’s view point and other factors, and it analyzes the limited visibility of the driver in the process of driving right turn. An effective and simplified calculation method based on design data for three dimensional (3D) stopping sight distance (S.S.D.) in high fill sections is proposed. Finally, the S.S.D. inspection of the actual highway, based on design speed and operating speed, is carried out, and the sight distance of the calculated point is judged by comparing the value with the normal value and the calculation result of the horizontal sightline offset. The results show that the method proposed in this paper is consistent with the sight distance results obtained by the horizontal sightline offset method, which indicates the calculation method is accurate and provides a technical reference for S.S.D. evaluation in highway safety engineering.
