This paper describes the work that has been done in the design and development of a wireless on-board diagnostic system (OBD II) fleet management system. The system aims to measure speed, distance, and fuel consumption of vehicles for tracking and analysis purposes. An OBD II reader is designed to measure speed and mass air flow, from which the distance and fuel consumption are also computed. This...
Many accidents happen while driving due to false estimation of the tailgating vehicle's distance and even while backing up or parking the vehicles in a parking lot. It is very important for the driver to know how close the tailgating vehicle. It is equally important to know the vicinity of the other vehicles and objects while parking or taking vehicle from the parking lots. The main objective of this...
Capacitated Vehicle Routing Problem (CVRP) is an issue of distribution of goods from a depot to a group of customers using vehicles with capacity limit by utilizing the limited number of vehicles and the capacity limit of each vehicle, to be able to distribute the goods to customers with an optimal route. Optimal route is a route that has the shortest distance and the fastest delivery time. In the...
Various studies have been conducted regarding vehicles and obstacle avoidance, but very few studies deal with the avoidance of obstacles that suddenly and unexpectedly appear during vehicle operation. We conduct automatic stopping control of the vehicle using a fuzzy control system when the vehicle stop suddenly. The propose system conducts stopping control of the vehicle depending on the distance...
This paper describes a fuzzy control strategy for the power management in electric vehicle. The goal is to determine the optimal distance while basing on the battery SOC and desired speed. The objective of this work is to predict the optimal distance traveled by the vehicle for such a battery SOC and a desired speed and to avoid the lack of energy. The Matlab simulation results demonstrate the effectiveness...
This paper documents the speed reduction impacts of intersection control beacon on rural highway on Xu song road of Beijing City, China. To determine the effect of intersection control beacon on stopping behaviors of drivers, a camera was used to collect valid samples at four times. After data preparation, there were 200 valid samples. In order to research the changing of vehicle speed and relationship...
As a means to improve the efficiency and flexibility of transportation systems, platooning technology suggests as a way of reducing carbon dioxide emissions and safe driving at a high speed velocity. This paper describes a control Algorithm for platooning and remaining the safety distance between vehicles. We also propose a control algorithm that enables when the vehicles to travel on the road in...
This paper focus on the database design for smart fuel consumption cost estimator (SFCCE). SFCCE is automated software that calculates the total amount of fuel cost for a car to travel based on the distance given, driving speed, weight capacity and current market fuel price cost. It has been developed by using Visual Basic .Net language and SQL Server database system. By deploying SFCCE, users obtain...
This paper describes the development of an image-based traveling information monitoring system. It provides a practical solution that can detect the driving feature and the running environment of the mobile in real time, especially the distances between the forward cars and our car. Moreover, this system can strengthen the management ability to prevent the traffic accidents for the drivers.
