You may want to slow the animation by adding some frame delay or adding some interpolation Alternatively you may start TRAFVU with the c command line option the recommended setting for concurrent operation 3 3 Link Drawing Considerations Two distinct sources of information affect the look of your network as depicted by TRAFVU roadway specifications that form the input to CORSIM and rules assumptions and connection logic used by TRAFVU CORSIM was initially developed without graphics or animation support Therefore CORSIM uses a minimal amount of geometric and roadway connection information just enough to support the simulation As CORSIM evolved and graphics support was added the input to CORSIM was minimally upgraded to Version 6 0 TRAFVU User s Guide Tips and Troubleshooting e 3 5 Tips and Troubleshooting support graphics Needless to say the current set of CORSIM input is insufficient to fully describe the look of a network To compensate for missing geometric input TRAFVU applies a set of rules to connect roadways and draw a network However ambiguities still exist under certain situations To compound drawing problems past versions of TRAFVU did not fully or consistently use even the small amount of geometric information provided by CORSIM input Thus a user could move a node to a new location or could change the length of a link without seeing an appropriate change in the network drawing In some situations a user had to e
