Bookmarks and Composite Filters
TransiCast bookmarks are inspired by web browser bookmarks. In TransiCast, bookmarks are used
to save and recall stop selections and destination filters. Bookmarks are also
used to for composite filters. Use composite filters when multiple routes
service a transit stop along a shared corridor.
The Bookmarks menu opens the following sub-menu:
A bookmark consists of the following elements:
- • Transit Data Server and agency
- • Stop name
- • Alarm threshold
Creating a Bookmark
Bookmarks are created for a selected stop. When a bookmark is created, TransiCast first finds the bookmarks that have previously been created for the selected stop. This list is displayed below the "New bookmark" item. There are two choices:
- • "New bookmark" creates a new bookmark consisting of the three elements listed above.
- • If an existing bookmark is selected, and a destination filter is set for the selected stop, TransiCast adds the destination filter to the selected bookmark. The current alarm threshold is also carried over to the existing bookmark. In this way, it is possible to compile multiple destination filters in a single bookmark. This is called a composite filter.
Selecting a Bookmark
Bookmarks are selected from previously created bookmarks. The
following screenshot shows an example of a list of previously created
bookmarks.
The "E Burnside & NE M L King" stop has a composite filter consisting of
two filter destinations, and an alarm horizon of four minutes. The "Skidmore
Fountain MAX Station" has no destination filters, and the refresh cycle is six
minutes. Both bookmarks call the Transit Data Server
"http://developer.trimet.org".
When a bookmark is selected, the values of the Transit Data Server and refresh cycle
are updated, and the destination filters are applied to the bookmarked
stop. The following screenshot shows the map view after selecting the "E
Burnside & NE M L King" stop.
Clearing a Bookmark
When Clear bookmark is selected from the bookmarks dialog, the list of current bookmarks is displayed. Tapping on a bookmark deletes the bookmark.
