Results of the simulation calculations

Large intersection with trianguiar isiands (case 6) 

In the case of simple two-phase control, there is no separate protected time for traffic turning left. This means that traffic turning left will tend to flow away during phase changes. 

Comparison of the control variants reveals the following basic findings

For this purpose a number of commercial simulation programs are available, such as ASPEN PLUS, PROSIM or CHEMCAD. The calculation of the unit operations is based on the usual foundations for the design of thermal /2.11,2.12, 2.13/, chemical /2.14, 2.15, 2.16, 2.17/, biological /2.18, 2.19, 2.20/ and mechanical processes 12.22, 2.21/. Furthermore, the calculation of the unit operations usually requires comprehensive data on chemical media. Since sufficiently precise data on chemical media are often not available or simplified assumptions have to be made, one will usually not rely only on the results of the simulation calculation. Principally, the reversed way of proceeding is also possible The simulation calculation is preceded and then completed by experimental analyses.
