Abstract Background We present a cellular phone-enhanced GPS tracking system (GPS mobile with CTG-001G receiver triangulation) suitable for urban carnivores, in tandem with appropriate home range analysis, as an additional tracking technology option in metropolitan settings. We conduct this proof-of-concept study working with the management of introduced invasive raccoons in Japan (and conditions implicit to this control program). Results Each tracking period averaged 17 days, and a tracking accuracy of

Conventional data collection methods lack real time information and involve excessive cost of installation and maintenance. A real-time, low cost travel time data collection system can be developed using mobile phones. This project examines the use of mobile phones for travel time prediction of public transit vehicles and develops a dynamic travel time prediction model. Personnel were employed in public transit vehicles with mobile phones and these mobile phones were tracked continuously. Space information of the mobile phones represents the position of the buses and movement pattern of these mobile phones in turn represents the movement pattern of the public buses. The starting and arrival time at sections obtained from the cellular database were used to get the travel time and speed. Results obtained were statistically significant and it shows that use of mobile phone for travel time data collection is a low cost data collection technique for Indian cities.

This paper discusses the suitability of mobile phone positioningdata for travel time information. The Finnish NationalRoad Administration Finnra has carried out a study on thesubject (1) and managed pilot installations on two road sections(6) in order to determine the feasibility of mobile phonetracking for traffic monitoring and management purposes. Accordingto the study and the pilots, the mobile phone positioningcan provide useful link monitoring data, i. e. the travel timeand speed. Mobile phone tracking was found to be a very promisingtool for implementing travel time information service todrivers.
