The bike GPS navigation system is designed for bicyclists that want a better sense of how to get around the College Park area, mainly the University of Maryland campus. This system is targeted generally towards those who ride their bicycles in those areas, based on their experience level and how often they ride their bikes. This system would be very beneficial towards those who do not know their way around the areas well, especially college freshman who are coming from different areas of the country and foreign countries. Even those who know their way around very well may find this system useful by using other various features. We are targeting those who want a convenient and easy way to find their way around the College Park area. This system will be catered towards those of various experience levels and knowledge of the overall area. The goal is to design a system that helps as many bicyclists as possible. The bike GPS will provide the user with instructions on how to get to their destination, where the local bike shops are, where to go for emergencies, what the weather will be like, etc. With preloaded destinations, the user can choose a bike route, rather than typing in a destination themselves. This system will serve a wide range of users, those who ride their bikes often, those who are very familiar with the area and those who are not, students and faculty at the University of Maryland, residents, and visitors. Bicyclists who are new to the area or who do not ride their bikes frequently are most likely to use the navigation features to find bike routes throughout the area. They can choose from a list of preloaded destinations. The bike GPS will be designed for anyone who rides their bike in the College Park area. The system will be designed in such a way that people can find their way around College Park with ease, whether it be parking lots, residence halls, nearby shops, etc. There are very similar products out there on the market that are similar to our system. Our goal was to differentiate our system from those that already exist. This is in terms of functionality, various capabilities, practicality, and usefulness. They are listed below, as well as, our resources used for research.
Academic Papers Title: “The global positioning system: theory and applications” Authors: Parkinson, Bradford W.; Spilker, James J., Jr. Publication: The global positioning system: theory and applications/ edited by Bradford W. Parkinson, James J. Spilker, Jr.; associate editors, Penina Axelrad, Per Enge. Washington, DC: American Institute of Aeronautics and Astronautics, 1996. Progress in astronautics and aeronautics; v. 163-164. Title: “Moving Beyond Observed Outcomes: Integrating Global Positioning Systems and Interactive Computer-Based Travel Behaviour Surveys” Authors: Doherty, Sean T.; Noël, Nathalie; Gosselin, Martin-Lee; Sirois, Claude; Ueno, Mami; and Theberge, François. Publication: Transportation Research Circular: Personal Travel: The Long and Short of It. Transportation Research Board, National Research Council, Washington, D.C. (in preparation). (6,397 words, 6 figures, 15 pages) This paper focuses on the use of Global Positioning Systems (GPS) to enhance and extend travel behavior survey methods. The paper first describes the testing of a passive vehicle-based GPS tracking system in Quebec City, and then describes the development of algorithms with a Geographic Information System (GIS) that can be used to automatically match the GPS data to road segments along a network, and identify stops along the way. Title: “Using Global Positioning Systems and Personal Digital Assistants for Personal Travel Surveys in the United States” Authors: Murakami, Elaine; Wagner, David P.; and Neumeister, David M. Information about daily travel patterns is generally captured using self-reported information from a written diary and telephone retrieval (or mail-back of diary forms). Problems with these self-reported methods include lack of reporting for short trips, poor data quality on travel start and end times, total trip times, and destination locations.
Other Relevant Websites Title: GPS World Publisher and Date: Questex Media Group, Inc, 2006 Site: http://www.gpsworld.com/gpsworld/ This is the official web site of GPS World magazine, which covers the global positioning industry. They provide information on the latest GPS news and products, which is used by many corporate managers, product designers, researchers, and system developers in the GPS industry. Their magazine not only covers GPS systems from the United States, but all over the world. Title: Trimble Publisher and Date: Trimble Navigation Ltd, 2006 Site: http://www.trimble.com/gps/index.shtml This site contains a tutorial on how GPS works. Trimble integrates a wide range of positioning technologies including GPS, laser, optical and inertial technologies with application software, wireless communications, and services to provide complete commercial solutions. Its integrated solutions allow customers to collect, manage and analyze complex information faster and easier, making them more productive, efficient and profitable.
Figure 1.2 - Transition Diagram This diagram represents the screens in the CycleMate prototype. From the menu screen, the user can access the Map, Directions, Weather, Emergency, and Tutorial. Each screen has a link on the top left that goes to the main screen. Also, Map, Directions, Emergency, and Weather are accessible by each of the other screens. For example, in the Directions screen, the user can access Map, Weather, and Emergency. In the Map screen, the user can access the Directions, Weather, and Emergency. From the Weather screen, the user can access Directions, Map, and Emergency. While on the Emergency screen, the user can access Directions, Map and Weather.
Prototype Screenshots For our final design, we decided that our program will have four major functions: Map, Direction, Weather, and Emergency. The program also has a Tutorial function which will guide first-time users on how to use the program. Figure 2.1 – Main Screen This is the main screen where user can access the system’s functions: Map, Weather, Directions, Emergency, and Tutorial. The user can access each via touch screen.
Figure 2.3 - Map Screen # The message “Destination Reached” immediately appears when the user reaches their destination.
Figure 2.4 – Directions Screen The Directions screen is where the user chooses from a list of preloaded destinations in the College Park area. For easy accessibility, there are links to Map, Weather, and Emergency. When the user presses “Calculate Route”, they are directed to the “Map” screen, which shows detailed directions from the user’s current location, which is determined by the GPS Satellite Technology, to a destination. The user will be asked to select a destination from a pre-loaded destination, which is on a drop-down menu. After that, the user presses the “Calculate Route” button, which will compute the shortest route from the user’s current location to the destination, and show it on the map. The ability for the user to enter in a destination would be available if the system is upgraded.
Figure 2.6 – Emergency Screen On the Emergency screen, there are two buttons, one to notify the police for personal safety or criminal activity emergency, and another one for medical emergency. All the user needs to do is hit the button, and policy/EMS will be notified. It also contains links to other options of the system: Map, Direction, and Weather.
Figure 2.7 – Tutorial # When the user clicks the Tutorial button on the main screen, there are instructions on how to use the Directions screen. There are navigation buttons at the bottom to help the user browse the Tutorial screens.
Figure 2.9 – Tutorial # When the user clicks the Next button from the previous screen (Figure 2.8), there are instructions on how to use the Weather screen.
Figure 2.10 – Tutorial # When the user clicks the Next button from the previous screen (Figure 2.9), there are instructions on how to use the Emergency screen.
