[sumo-user] Wiedemann 74 CFM in SUMO
|
Hi,
as you already noticed, you cannot transfer the parameters directly. Some relations can be extracted from the source code at https://github.com/eclipse-sumo/sumo/blob/main/src/microsim/cfmodels/MSCFModel_Wiedemann.cpp :
- standstill distance AX = 1 + vehicle length + 2*security
- multiplicative part CX = 25*(1 + security + estimation)
The additive part is computed using the other input and some constants.
Best regards
Mirko

Hello
how can I use wiedemann 74 car following model parameters calibrated in vissim by parameters such as average standstill distance,Additive part of safety distance, and Multiplicative part of safety distance but in sumo it has other parameters(i.e., security, estimation)
