The paper exposes the experimental validation of a synergic INS/GPS navigator with direct application in the assistive positioning of the old people. The data fusion algorithm used in the integration procedure of the two navigators is based on a Kalman filter. For the experimental testing, the detection platform was boarded on a land vehicle and the data were radio transmitted to a base station which...
GPS-based applications make travelling easier, supplying information about routes, such as real-time traffic, Estimated Time of Arrival, faster or cheaper path. These applications exploit digital maps supplied by specific companies, often updated also thanks to user-submitted data. The aim of this work is to show an event driven system for territory mapping and monitoring, using multi-hop wireless...
In today's days, due to increase in number of vehicles the probability of accidents are also increasing. The user should be aware of the road circumstances for safety purpose. Several methods requires installing dedicated hardware in vehicle which are expensive. so we have designed a Smart-phone based method which uses a Accelerometer and GPS sensors to analyze the road conditions. The designed system...
This research is basically on an electronic device which can be used at the time of emergency while driving a vehicle. It has embedded the concept of wireless communication i.e. Zigbee and GSM and many other sensors by the help of which immediate help can be delivered to the person who has met with an accident. The overall structure is based on the AT89S52 microcontroller. Also the key role of DTMF...
A new data fusion method has been developed which theoretically provides relevant information about traffic states at all crucial locations of urban road networks. This mainly based on Floating Car Data(FCD). FCD based on the collection of localisation data, speed, direction of travel and time information from GPS in vehicles that are being driven. The scope of the project is to development and creation...
Our research has been targeted towards building an integrated system for emergency rescue services in the event of a road accident. The project focuses on building an infrastructure which vehicle safety authorities can implement to enhance the reporting of vehicle crashes, provide post-crash analysis using motion sensors, record of the event in images and reduce the time it takes for emergency rescue...
Suppression of mosquito breeding is a mandatory first step to reduce the source of major mosquito-borne diseases like Malaria and Dengue fever. This paper deals with an innovative method for the identification of mosquito breeding sites (stagnant pools), using wireless networking technologies and removal of stagnant water through electromechanical pumping systems. The stagnant water areas are first...
In the present scenario, mobile phone is considered to be one of the prime causes of road accidents. In this paper we have used mobile phone itself as a means of safe and impervious driving. We have successfully detected and analysed the driving behaviour - Acceleration/Deceleration, Lane Change. Also the road anomalies like bumps and potholes are detected and data is processed to generate alerts...
Map matching is the process of finding a match for each GPS point in a vehicle's trajectory to roads on a digital map. Extensive research has been conducted during the last years yielding many algorithms based on different approaches. One of the challenges that face those algorithms is the interruption of GPS signals that occurs specially in dense urban environments. In these cases on-board sensors...
This paper proposes a three-dimensional (3D) map generation algorithm for energy management systems on electric vehicles (EV) or hybrid electric vehicles (HEV). The 3D road geometry of the predefined driving path can be crucial information for energy management systems to design an optimal driving strategy. A single GPS receiver can provide the 3D position of a road profile; however, it is not accurate...
Smartphones have been widely integrated with GPS receiver, which may provide accurate location information of vehicles without cost increase. Traditionally, LBS applications obtain vehicle locations then using the Hypertext Transfer Protocol (HTTP) protocol uploaded to central servers with a fixed frequency. In this paper, we exploit an intelligent strategy of GPS sensing and transmitting. Explicitly,...
Real-time parking availability information is important in urban areas, and if available could reduce congestion, pollution, and gas consumption. In this paper, we present a software solution called PhonePark for detecting the availability of on-street parking spaces. The solution uses the GPS and/or accelerometer sensors in a traveler's mobile phone to automatically detect when and where the traveler...
GPS receivers have a major drawback: they don't work properly under multi-storey concrete structures, for e.g. in underground car parks, University buildings, shopping malls, factory complexes etc. A navigation system for such huge enclosed spaces, which does not rely on a GPS is very desirable for visitors to such places who do not know the layout of the place. This paper presents the design and...
This paper proposes a novel dangerous driving report system using a smart phone platform. By collecting a stream of data through built-in GPS receiver, a time series of speed profile can be obtained for a given journey. An algorithm is proposed to detect anomaly in speed profile in order to detect whether a vehicle is speeding. As well as the ability to alert passengers in real-time in the case of...
We evaluate the integration of on-board diagnostics (OBD) speed measurements with sparse and/or missing GPS data for vehicle trajectory estimation using an extended Kalman filter. The suggested framework is relevant to the deployment of low-power, low-cost GPS receivers in the context of mobile and pervasive sensing. Our algorithm is capable of handling sensors at different sampling rates and comprises...
The threat of terrorism is a constant reminder of the significance of developing effective strategies to safeguard the population. This is particularly important in large, densely populated areas, which can often be the primary targets of a terrorist attack. In such a situation, the implementation of a depopulation plan becomes very challenging to manage. This paper explores one possible method of...
GPS receiver performance can suffer in difficult environments such as urban canyons and heavy foliage. Inertial sensors provide information between GPS updates and can enhance the position solution in a GPS/INS architecture. Additional information from safety sensors already on the vehicle, such as lane departure warning (LDW) sensors, can enhance the navigation solution further by constraining inertial...
