![]() ![]() Ratio of cars going straight, turn left and turn rightĪlso, a practical word of warning when working with the road traffic library: you might run into model errors when cars try to turn left but still sit on the wrong lane.Number of cars arriving from each corner.However, the input data is pure guesswork at this point so I will need to do some field investigations on: We never hit a traffic jam but short queues regularly form. To be honest, this resembles my experience of the crossroads quite closely already. Buses arrive according to the actual schedule. The final model: cars move and turn based on guess-work data. I will do some more research here, but let’s get the beauty to work first: What it looks likeīefore running the model, I went into my trusted system of gut-feeling and adjusted the probabilities of car directions (much more likely to go straight on than turn) based on my personal experience. Road traffic library blocks: everything is deleted once leaving the model. Now, entities are coded to behave like cars, including physical properties like acceleration and human-factors like lane-changing. However, those entities did not have “behaviour” of their own. Remember that the process library is really good at moving entities through a system of queues and delays while potentially using some resources. ![]() Their idea is as genius as it is elegant: essentially, they took the existing process library (that you use to model discrete-event processes) and amended the behaviour of the entities to match that of cars. It is important to understand what the AnyLogic team has done at the core of the library. ![]() And this little problem gave me the chance to play around with it some more. With AnyLogic 7.3, we can now play with the road traffic library. We have seen pedestrians for a while now, then came the train library and recently the fluid library. I know, AnyLogic keeps releasing new libraries and it is sometimes hard to keep up. There are three suggestions: additional traffic light phases for left-turning vehicles speed limits and longer traffic light phases for pedestrians.
