  1. SunGuide® Software Development ProjectRelease 4.3 Express Lanes Enhancements Design ReviewDecember 15, 2009 R4.3 Design Review

  2. Meeting Objectives • Requirements: • Provide a high level review • Provide SwRI’s interpretation (via a design) of the requirements • Design • High level architectural overview • Operator actions and reactions • Prototype screens / reports • Not an objective: • Revise requirements R4.3 Design Review

  3. Release 4.3 Express Lanes Activities R4.3 Design Review

  4. operator confirmation Express Lanes Operator ELM Detectors GUI TSS Toll Rate Messages, Middleware Status Databus DMSSubsystem PS Toll PATRON SunGuide CSRs Toll Rates Viewer Database Florida’s Turnpike SunGuide E.L. Signs Express Lanes Enhancements Overview Goal is to implement a direct interaction from ELM (Express Lanes Manager) to other SunGuide® components to eliminate manual data entry and automate some operator tasks. R4.3 Design Review

  5. Functionality Provided for Clients • Existing functionality will allow an authenticated/subscribed client to: • Set Mode/Rate • Receive status of Segments • Receive configuration of Segments and Pricing • Receive status of Toll Rate, Gantry, and Lane Status Signs • Receive Pricing Alerts • Receive Pricing Acknowledgements • Added functionality will allow an authenticated client to • Add Pricing alerts R4.3 Design Review

  6. XML Interface • Pricing supports XML communication to clients on a request/response basis. • Responses may be sent to multiple clients if they have the proper subscriptions. • Status updates come in messages originated in the subsystem, and are delivered to subscribed clients. • The Pricing ICD document describes communication between the Pricing subsystem and the client. R4.3 Design Review

  7. Pricing Changes Overview Some of Pricing’s previous modes have been renamed and “Dynamic” mode has been added. Middleware Rate Adjustment is no longer a mode, but can adjust the rate sent to Turnpike, while leaving the current mode unchanged. R4.3 Design Review

  8. Pricing Changes Overview • Clients can send mode / rate changes requests • Dynamic mode allows clients to change rates based on traffic data without operator approval • Mode / rate change requests may also contain a transit time for each toll rate sign to allow changing the signs based on traffic data • Offline synchronization file may be generated to sync SunGuide and Patron in the event of extended communication outage • On a restart of Pricing, operators are prompted to approve a SunGuidestartup mode, and optionally create rate history while Pricing down. R4.3 Design Review

  9. Mode Choices • Middleware Rate Adjustment has been removed from the choice of Modes. • Also, note the Operators cannot set the mode to “Dynamic” from the Operator Map. R4.3 Design Review

  10. Middleware Rate Adjustment GUI • New Middleware Adjustment button R4.3 Design Review

  11. Rate Adjustment Alerts When a new rate is sent to Middleware while a Rate Adjustment is in effect, an alert is generated. The alert will allow the user to continue or end the current Rate Adjustment. If the Rate Adjustment is continued, a new Rate Adjustment is sent to the Middleware which overrides the rate that generated the alert. 11 R4.3 Design Review

  12. Offline Synchronization Offline synchronization file can be used during times of extended communication loss so data consistency can be maintained. Daily, SunGuide will generate a file of pending rates that need to be sent to Patron. This is the format of the offline rates that SunGuide will provide. R4.3 Design Review

  13. Offline Synchronization A file can then be delivered to SunGuide that show the rates that were acknowledged by Patron. This is the format of the acknowledged rates that should be provided to SunGuide. Acknowledged rates will then be updated in SunGuide and the database. R4.3 Design Review

  14. Pricing Restarts When pricing starts, no segments will be tolling. Pricing will send a message to operators that contain a suggestion for the startup state for each segment. Operators may chose the starting mode, rate, and if there is a Middleware adjustment. Operator will still be able to view DMSs to help make their decision on the startup state. They will also be able to add rates that were effective while Pricing was not running. Upon receiving the startup state from operators, Pricing will then send rates to Patron and start tolling on each segment in the approved mode. R4.3 Design Review

  15. Restart Pop-Up GUI 15 R4.3 Design Review

  16. New Configuration Options • Admin Editor will allow the following configuration options • Pricing Configuration • Suppress Rate Change Alert – Operators will no longer be able to view or acknowledge Rate Change Alerts via the Operator Map (alerts still published to Pricing clients, just not displayed on the Operator Map) • Default Lane Status Text for Open, Closed, and Tolling • Default Minimum, Maximum Transit Time values for each Toll Rate Sign and Distance to the Gantry • Maximum Toll Rate for each segment R4.3 Design Review

  17. Admin Editor Screens R4.3 Design Review

  18. Admin Editor Screens R4.3 Design Review

  19. Toll Viewer Date/Time Selection • Addition of textbox to allow pasting of date/time in a configurable format. • Dropdown selections and textbox will stay in sync • Modifying the textbox will change the dropdowns • Modifying the dropdowns will change the textbox R4.3 Design Review

  20. Toll Viewer Date/Time Selection • Time range selection fields added to the top of each results page • Are the full selection fields (report type, etc) desired on this page as well? • Requirement called out date/time fields • Other fields hidden to save space on page R4.3 Design Review

  21. Toll Viewer Detail Report Updates • Categories of data changed • Toll Rate History replacing Summary • DMS Communication attempts moved to just prior to events at the end • Override History changed to Mode Changes R4.3 Design Review

  22. Toll Viewer Detail Report Updates • Mode History • The historical data from prior to the upgrade will still have gaps (TOD rates not tracked as overrides in the current release) • From the upgrade date going forward, all modes (including TOD) will appear in this table R4.3 Design Review

  23. Toll Viewer Detail Report Updates • DMS Communication • Retry attempts combined – will only show initial attempt and the eventual successful posting (if any) for each message • End Times added (for successful messages) • Initial message for each DMS shown even if an attempt for that message was not made during the selected time frame • Rows highlighted in orange which do not match the message scheduled by Pricing • Similar to TOD mode issue listed above, messages archived from the current software will show as suspect as “scheduled” messages were not tracked • Messages from after the update will appear in the same green background like the other rows when they match R4.3 Design Review
