Method Detail

shouldUseJms

public static boolean shouldUseJms()

Specifies whether should use JMS to queue AVL data or if should process directly using single thread.

Returns:

getSecondsBetweenAvlFeedPolling

public static int getSecondsBetweenAvlFeedPolling()

How frequently an AVL feed should be polled for new data.

Returns:

getAvlFeedTimeoutInMSecs

public static int getAvlFeedTimeoutInMSecs()

For when polling AVL XML feed.

Returns:

getMaxAvlSpeed

public static double getMaxAvlSpeed()

Max speed that an AVL report is allowed to have.

Returns:

max speed in m/s

minSpeedForValidHeading

public static double minSpeedForValidHeading()

If AVL report speed is below this threshold then the heading is not considered valid.

Returns:

getMinAvlLatitude

public static float getMinAvlLatitude()

For filtering out bad AVL reports. The default values of latitude 15.0 to 55.0 and longitude of -135.0 to -60.0 are for North America, including Mexico and Canada. Can see maps of lat/lon at http://www.mapsofworld.com/lat_long/north-america.html

Returns:

getMinAvlLatitudeParamName

public static java.lang.String getMinAvlLatitudeParamName()

getMaxAvlLatitude

public static float getMaxAvlLatitude()

getMaxAvlLatitudeParamName

public static java.lang.String getMaxAvlLatitudeParamName()

getMinAvlLongitude

public static float getMinAvlLongitude()

getMinAvlLongitudeParamName

public static java.lang.String getMinAvlLongitudeParamName()

getMaxAvlLongitude

public static float getMaxAvlLongitude()

getMaxAvlLongitudeParamName

public static java.lang.String getMaxAvlLongitudeParamName()

getUnpredictableAssignmentsRegEx

public static java.lang.String getUnpredictableAssignmentsRegEx()

So can filter out unpredictable assignments such as for training coaches, service vehicles, or simply vehicles that are not in service and should not be attempted to be made predictable. Returns empty string, the default value if transitime.avl.unpredictableAssignmentsRegEx is not set.

getMinTimeBetweenAvlReportsSecs

public static int getMinTimeBetweenAvlReportsSecs()

Minimum allowable time in seconds between AVL reports for a vehicle. If get a report closer than this number of seconds to the previous one then the new report is filtered out and not processed. Important for when reporting rate is really high, such as every few seconds.

shouldLogToStdOut

public static boolean shouldLogToStdOut()

For debugging. Logs each AVL report to stdout if set to true. Default is false.

Returns:
