Stop models
Trip_destinations completed
Ran into the problem where a work tour with walk mode has a university stop, but there are no universities located within walking distance and so the model crashes
Solution borrowed from DaySim - re-run earlier models with new random numbers for failing choosers since the number of occurrences is small and therefore the statistical results are insignificant
Reworked code to handle missing trip types (atwork, subtour, school, work, etc.) for small samples, such as just one household
Fixed the destination fail - mark failed trips and skip them, setting subsequent trip’s origin to previous trips dest (version 0)
Fixed the destination fail - retry failed trips (and their leg-mate cohorts) rerunning both trip_purpose and trip_dest on failed trips with new random numbers (version 1). If any trips still failing after MAX_ITERATIONS, then fall back to version 0
Tracking failure by iteration so we can see the impact; @Jeff will share the numbers from the full run
Can now run just a select list of households through the models as a result
Will start implementing trip timing and mode choice next week
Documentation / release
Still working on updated documentation
Added a flow chart of the example TM1 sub-models and an image map with links to sub-model configuration files
