A general architecture in support of interactive, multimedia, location-based mobile applications

Sean J. Barbeau; Miguel A. Labrador; Philip L Winters; Rafael Perez; Nevine Labib Georggi

The widespread use of cellular telephones and the availability of user-location information are facilitating the development of new personalized, location-based applications. However, as of today, most of these applications are unidirectional and text-based where the user subscribes and the system sends a text message when appropriate. This article describes a modular and general architecture that supports the development of interactive, multimedia, location-based applications, providing an extra level of service to the users. The flexibility of the architecture is demonstrated by presenting the wireless safety security system (Wi-Via) and other potential applications

Dynamic Management of Real-Time Location Data on GPS-Enabled Mobile Phones

Advanced location based services have the ability to track users with Global Positioning System (GPS)-enabled cell phones in real-time. These applications share a common problem; the continuous calculation and transmission of GPS fixes from the mobile phone to a server consumes a considerable amount of energy and increases data transmission costs. Therefore, an application-level algorithm is necessary to reduce the number of GPS fixes calculated and transmitted, while continuing to track the user in real-time and record an accurate representation of his or her travel path. In this paper, two complementary algorithms are presented: the critical point (CP) algorithm, which filters data points to be transmitted to the server, and the location-aware state machine, which dynamically manages the frequency of the location re-calculation update rate. Both algorithms were implemented in TRAC-IT, a Java Micro Edition (Java ME) application designed to automatically collect user travel behavior; the proposed algorithms allow TRAC-IT to build an accurate representation of the users path with a considerably reduced number of fixes while significantly extending mobile device battery life.

The Location-Aware Information Systems Client (LAISYC) supports intelligent, real-time, mobile applications for GPS-enabled mobile phones by dynamically adjusting platform parameters for application performance while conserving device resources such as battery life.

Analysis of Alcohol-Related Motorcycle Crashes in Florida and Recommended Countermeasures

Patricia A. Turner; Nevine Labib Georggi

Although much progress has been made in reducing alcohol-related crash fatalities involving motor vehicles, the same success has not been demonstrated with motorcycles. Because the problem associated with drinking and riding is significant in Florida, the Center for Urban Transportation Research (CUTR) conducted a comprehensive analysis of motorcycle-alcohol crashes from 1993 to 1997 to understand how and why these crashes occur. CUTR also surveyed states about alcohol programs that target motorcyclists to gather information on potential countermeasures to reduce motorcycle-alcohol injuries and deaths in Florida. The study examined human-related and physical aspects of alcohol-related motorcycle crashes over the 5-year period to help establish an identity for this crash type. Examined human-related crash aspects included age and gender, alcohol use, licensing status, and helmet usage. Physical crash aspects examined included temporal patterns—time of day, day of week, and monthly trends—and contributing factors—first harmful event, road, environmental, and human factors—that cause bodily injuries or property damage. Major study recommendations include increasing efforts to get more motorcyclists properly licensed, greater exposure of messages to motorcyclists about the dangers of drinking and riding, and focused statewide public education and information campaigns. The study concludes with five major categories of countermeasures and recommendations to address the motorcycle-alcohol problem, including public information and education campaigns, promotional activities, enforcement efforts, community-based interventions, and data-collection needs.

Global Positioning System Integrated with Personalized Real-Time Transit Information from Automatic Vehicle Location

Sean J. Barbeau; Nevine Labib Georggi; Philip L Winters

Navigation of a transit system can be a major obstacle to new riders, especially special-needs populations and tourists. For those with cognitive disabilities (approximately 14.3 million Americans, or 6% of the population), it is challenging to plan and execute a trip without assistance. A travel assistance device (TAD) software prototype for Global Positioning System–enabled phones was developed to aid new transit riders, especially those who are cognitively disabled. When riders approach their stops, the TAD vibrates and delivers audio and visual messages to the riders to request a stop and exit the vehicle. This paper reports the results of a study that integrated communication with an automatic vehicle location (AVL) system on transit vehicles into TAD, with new features, including personalized notices of estimated vehicle arrival time and of vehicle arrival. Implementation issues addressed include the limitations of accessing AVL data for real-time consumer use, integration of different transit agency data sources, and consideration of the effects of software applications (e.g., wireless data communication) on mobile phone functionality (e.g., battery life).
