DATABASE DESIGN AND Sample Clauses

DATABASE DESIGN AND. IMPLEMENTATION The large amount of complex data collected for analysis required a well-designed and organized database. The database design in this study followed the Entity/Relationship (E/R) diagram approach. A detailed introduction of the E/R diagram approach is available in the report by Xxxxxx-Xxxxxx et al. (2002). Figure 4-1 shows the E/R diagram of the database. GPS Position N GPS Position W Day Time Trip Block Trip No. TSP trip TSP route TSP block Schedule at bus stop Speed Heading Schedule at intersection Bus Location Related HDOP Bus Assignment Intersection ID Satellites Related Incident delay Related Actual run time Bus Operation Intersection ID TSP Calling Scheduled Run time Late time Trip No. Detected time Priority request Results to request Trip No. Day No. of Stops No. of lifts Operator experience Figure 4-1 E/R Diagram of Database According to Figure 4-1, the following database objects are needed: Entities: • Bus location • Bus assignment information • Bus operation information • TSP calling Relationships: • Belong to: binary, many-one • Related to: binary, many-one Relational schemas: • Bus location (Trip block, Time [hhmmss], Day [mmddyy], GPS coordination N, GPS coordination W, Speed, Heading, HDOP, Satellites) • Bus Assignment Information (Trip No., TSP trip, Route No., Trip block, schedule at each time-point on weekday/ Saturday/ Sunday and holiday, schedule at each intersection with TSP sensor on weekday/ Saturday/ Sunday and holiday, Intersection ID) • Bus Operation Information (Trip No., Day, No. of stops at bus stops, No. of wheel chair/bicycle lifts, operator experience [year], late time at the first bus stop [second], scheduled running time [second], actual running time [second], incident delay [second]) • TSP Calls (Intersection ID, coordination N, coordination W, Trip No., Bus detected time, Day, Priority request made, Results to request) Foreign Keys: • (Buslocation.Tripblock, Buslocation.Time, Xxxxxxxxxxx.Xxx) references BusAssignmentInformation.TripNo. • (BusOperationInformation.TripNo, XxxXxxxxxxxxXxxxxxxxxxx.Xxx) references BusAssignmentInformation.TripNo. • (TSPCalls.IntersectionID) references BusAssignmentInformation.TripNo.. In this study, we used the Structured Query Language (SQL) for data management. This database was implemented in the Microsoft SQL Server 2000.
