Car Movement and Traffic Management System (CMTM)

Traffic Management
Now we look at the Traffic Management portion of this system. This involves the through freight traffic. Through traffic arrives on the route via a Portal and leaves via another Portal with no delivery to a local industry. To start this process, a traffic plan needs to be formulated.

Here is an example for a route that has an East-west mainline with a branch line headed south. This route also interchanges traffic with the CNW and the CGW. The following percentages are for through traffic and does not include traffic to local industries.

Trains from the west - 70% of cars go to PortalEast, 20% to the PortalSouth, 5% to CGW and 5% to CNW.
Trains from the east - 75% of cars go to PortalWest, 5% to the PortalSouth, 10% to CGW and 10% to CNW
Trains from the south - 80% of cars go to PortalWest, 15% to CGW and 5% to CNW
Trains from CGW - 40% of cars go to PortalWest, 30% to PortalSouth, 20% to PortalEast and 10% to CNW
Trains from CNW - 50% of cars go to PortalSouth, 40% to PortalWest, 10% to CGW

These traffic patterns are created by entering the appropriate number of records into the Movement Records Spreadsheet that reflect these ratios. To maintain these ratios for 7 days of the week, create the following records with all days selected. For the west portal, make twenty records with the PortalWest as the beginning Location. Of these twenty records, make the Destination 1 field of 14 of these records PortalEast, 4 to PortalSouth, one to PortalCGW and one to PortalCNW. As the day progresses, these records will be used again and again, maintaining the desired traffic ratios. Use this method for creating the records for the other portals. Daily patterns can be changed by making more records specific to days you want to change.
