This article investigates the use of artificial neural networks for developing an alternative integration scheme of low cost Microelectromechanical System (MEMS) Inertial Navigation System (INS) and Global Positioning System (GPS) for vehicular navigation applications. The primary objective is to overcome the limitations of current INS/GPS integration scheme and improve the positioning accuracy during GPS signal blockages. The results presented in this article indicated that the proposed technique was able to provide 47% and 78% improvement in terms of positioning accuracy during GPS signal blockages.
Bangkok to introduce GPS to its fleet of taxis
Bangkok has opened the first of 150 new electronic taxi stands that will allow pedestrians to summon a taxi by pressing a green button, signaling a dispatcher to send a taxi. The devices will display the estimated arrival time and license plate number of the approaching taxi. Taxis will be equipped with GPS as part of the service. The first arch-roofed electronic taxi stand was unveiled last week outside a superstore on the city’s Phahonyotin Road, while the remaining stands are expected to be installed across the city by November. Besides helping Bangkok pedestrians easily hail taxis, the stands are meant to keep cab drivers from wasting fuel by driving around the city in search of fares. www.chinapost.com.tw
Road Construction Project uses positioning technology
Trimble announced that it has been selected as the preferred supplier of machine control and survey equipment for Thiess John Holland, the lead contractor building Australia’s largest road project¯EastLink in Melbourne. With total construction costs of AU$2.5 billion (US$1.9 billion), the scale of work required for timely completion of Melbourne’s EastLink is beyond that ever tackled before on any single infrastructure project in Australia. EastLink’s three-lane, freeway-standard road is expected to be built over three and a half years. Construction includes two million square meters of paved road, more than eighty bridges, seventeen interchanges and 1.6 kilometers three-lane twin tunnels. The project will deliver Melbourne’s second fully-electronic tollway, comprising about 45 kilometers of freeway-standard road connecting the city’s eastern and south-eastern suburbs.

Maharashtra was the first state in the country to have a disaster management plan. It all started with the Latur Earthquake of 1993. As a part of response programme, the Maharashtra Emergency Earthquake Rehabilitation Project (MEERP) was launched the same year. This later led to the exercise of preparing a State Disaster Management Plan. The World Bank, United Nations Development Program (UNDP) as well as several bilateral donor agencies supported the initiative.
The 26th July 2005 floods in Mumbai, which caused widespread destruction, deaths and damage to property and infrastructure, have once again highlighted the importance of disaster mitigation and management using modern technology. Monitoring natural disasters like floods, earthquakes, volcanic eruptions, landslides, avalanches, cyclones, etc., with the ultimate aim of predicting them, and managing the rescue and rehabilitation operations during and after such calamities, have been discussed in various forums in the past. The devastating Latur earthquake of 1993, the Bhuj earthquake of 2001, the Orissa cyclone, and the recent tsunami after the Sumatra earthquake, which caused extensive damage in terms of human lives and property, have drawn the attention of the Indian scientific community to the immediate need of monitoring and managing such disasters in our country in the most effective, efficient and economic manner. Traditionally, maps are being used for this purpose, as an effective tool, since ancient times. However, with the introduction of computeraided techniques in map-making, and the space technology in surveying and mapping, the utility of geodetic and map data for this important activity has increased many-fold. However, a well-coordinated programme for optimum utilization of these important technological tools, resulting in efficient management of the disasters, still remains an elusive dream of administrators, scientists and technologists.
