Abstract:

Pejanggik intersection and Caturwarga intersection are unsignalized intersections in Mataram City. Both intersections have the same characteristics, namely they both have four arms. The location of the two intersections close together causes frequent traffic delays. For this reason, research is needed to optimize the performance of these two unsignalized intersections.The method used to analyze the two intersections is the Indonesian Road Capacity Manual (1997). The data used is primary and secondary data, such as traffic volume, capacity, degree of saturation, delays and queuing opportunities

The necessity of using a mathematical approach when assessing delays is proved. The factors influencing transport delays when driving through unsignalized intersections are presented. An integrated mathematical model is derived, which makes it possible to estimate the load factor at unsignalized intersections.

Passenger Car Equivalent (PCE) is expected to be very accurate because it is very important in determining the capacity, degree of saturation, and handling of unsignalized intersections. Several methods have been used to estimate the PCE value, but based on the literature review, it is stated that the occupancy time method and the speed method are the most applicable for the unsignalized intersection conditions. This study aims to determine the most appropriate PCE value by comparing the occupancy time method and the speed method. To determine the most appropriate method in calculating the PCE

Abstract:

A high percentage of highway crashes in the United States occur at intersections. These crashes result in property damage, lost productivity, injury, and even death. Identifying intersections associated with high crash rates is very important to minimize future crashes. Identifying the high-risk intersections before crashes occur is a challenge that every traffic/safety analyst faces. Traffic conflict technique is a solution to this problem. Extensive research efforts have been made to estimate mean and abnormal traffic conflict counts at four-legged intersections with varying lane and approac

The study encompassed three particular locations of unsignalized crosswalks: on the street section between intersections, in the zone of intersection impact, and in the zone of intersection itself. The study revealed that the major impact on traffic jams is observed at a distance of 50-100 m from the unsignalized crosswalk. The study analyses pedestrian behavior and waiting time at such crosswalks. It was confirmed that the pedestrians did not immediately use their priority before passing.

The research highlights that the current capacity of these intersections is insufficient to handle the growing traffic demand. For instance, un

Abstract:

An effective traffic control strategy will improve travel reliability in urban transportation networks. Lack of coordination between vehicles, however, exacerbates congestion due mainly to frequent stops at unsignalized intersections. It is beneficial to develop a conflict-free cooperation method that collects basic safety message from multiple approaching Connected and Autonomous Vehicles (for short, CAVs) and guarantees efficient unsignalized intersection operations with safe and incident free vehicle maneuvers.

Buses constitute a crucial component of public transportation systems in numerous urban centers. Integrating autonomous driving technology into the bus transportation ecosystem has the potential to enhance overall urban mobility. The management of mixed traffic at intersections, involving both private vehicles and buses, particularly in the presence of bus lanes, presents several formidable challenges. This study proposes a preemptive-level-based cooperative autonomous vehicle (AV) trajectory optimization for intersections with mixed traffic. It takes into account dynamic changes in the inters

The performance of the intersection often decreases which has an impact on road users due to vehicle queues, decreased speed, decreased environmental quality and increased delays. The benchmarks for evaluating the performance of intersections are capacity, queuing opportunities, intersection delays and degrees of

The videotape was used at eight unsignalized intersections for one complete peak hour on weekdays. Any at-grade intersection that is not controlled by a traffic signal is defined as an "unsignalized intersection." The results showed that 48% out of 1,208 drivers took the decision to stop completely compared to 52% who chose to keep driving. Female drivers (75%) were observed to stop at intersections more frequently than male drivers. In terms of vehicle

Abstract Autonomous driving is a promising technology to, among many aspects, improve road safety. There are however several scenarios that are challenging for autonomous vehicles. One of these are unsignalized junctions. There exist scenarios in which there is no clear regulation as to is allowed to drive first. Instead, communication and cooperation are necessary to solve such scenarios. This is especially challenging when interacting with human drivers. In this work we focus on unsignalized T-intersections. For that scenario we propose a discrete event system (DES) that is able to solve the

Abstract:

As part of transportation infrastructure, road infrastructure is essential in increasing community mobility and accessibility. When traffic volume increases or changes its characteristics, the intersection is the first thing that shows the inability to serve the increased traffic. Because intersections are critical points of the traffic system where vehicles from different directions meet, obstacles and traffic jams at intersections will affect the capacity of the road concerned, so the level of service at the intersection will decrease, including the speed, safety, and comfort of road users.T

Road traffic flow models allow the development and testing of intelligent transportation solutions. Macroscopic intersection models are especially relevant for the simulation of large traffic networks. In this article, we study four first-order signalized and unsignalized intersection models. The two unsignalized approaches are the first-in-first-out (FIFO) model (roundabout-type intersection) and an optimal non-FIFO model (highway-type intersection). The optimal control operates upstream for the first signalized intersection model. It occurs downstream for the second signalized model. All fou
