We acknowledge that this has now been withdrawn but it is still a useful measure to demonstrate model stability, and has never been queried at audit.įigure 2 shows an example of the summary convergence table we produce and Figure 3 shows an example of how the path/edge volume and travel time percentages are created (using Seed Run 20 from Figure 2).įigure 4 - Example Calculation of Convergence Levels - Seed Run 20 The 1% difference check for Total Travel Time is based on previous DMRB guidance which required the “change in user costs or time spent within the network should be less than 1% for four consecutive iterations”. The volume and travel time differences from the *CVA file are compared against the criteria in Figure 1.

The ‘Total Travel Time’ value from the Network Performance evaluation to check the overall network difference.

The *CVA file generated by VISSIM to check the volume and travel time differences.

These can cause slight variances in signal timings from seed run to see run, which in turn affects the level of convergence.Īs a result of the above, our current approach to assess convergence is to use two outputs: Our microsimulation models also contain elements such as vehicle actuated signals and pedestrian demand inputs. VISSIM Model ConvergenceĪs a recap, convergence criteria for VISSIM models is best summarised in TfL’s MAP Engineer Guide v3.5 ( ), P140 as shown in Figure 1.įigure 2 - Covergence Set-Up in Dynamic Assignment As a result, we have produced this post to go into detail on what the current convergence guidance is, what methodology we adopt, the limitations with it and a proposed revised approach to demonstrate model convergence. PeMS), and a manual survey of onramps.įollowing PJA’s attendance at the PTV User Group in London on 4 th November 2019, one of the key messages that we took away from the conference was the importance of model convergence and understanding the levels of convergence achieved before running for results.Īt PJA, we use PTV VISSIM on a daily basis and are all too familiar with model convergence, the difficulties faced as models get bigger and more complex. Implement the C code in a simulation DLL for VisSim. VisSim is a signal-flow simulation tool with strength in embedded systems programming. The use of real time data in combination with optimization algorithms reveals solid traffic prediction up to 60 mins in advance and calculates trips most efficiently. PTV software equips users with the right tools to monitor, optimize and control traffic & logistics. Doc folder of your Vissim installation directory.
