 Timetable production is an interactive process involving many constraints and conflicting goals. Operational constraints often cause impacts that are not initially obvious. Furthermore, the system-wide impacts of local timetable changes are not directly evident in large railway networks.
Viriato’s Trip Time Analysis module enables timetable planners to compare alternative timetables and analyze timetable and service quality. It starts by identifying all meaningful connections based on the timetable data, trip times and user-defined transfer times. Once the connections have been identified, Viriato calculates the alternative’s most important customer and operational qualities. The Trip Time Analysis module enables timetable planners to thoroughly evaluate alternative timetables by providing many different analysis tools.
Functionality
- Determine all possible connections with: shortest trip time, fewest transfers and shortest weighted trip time, for any selection of origin/destination pairs;
- Compare summary and specific origin/destination pair data for alternative timetables;
- Set user-defined transfer weighting values.
Display/Output
- Display connection data in table format based on 24 criteria (e.g. trip time, wait time, distance, speed, etc.);
- Use filters to display selected data;
- Aggregate data based on various criteria;
- Export data for use in Geographic Information Systems.
