Hi Jakob, thank you for your answer. Indeed flowrouter doenst need speed data because it solves a maximum flow problem and takes the count data as capacity.
Thanks for the link. Now I know my options but 1. Do you have any experience or are you aware of references about the quality of the demand modeling with induction loop count data with flowrouter or the another one? I want to get an Idea how many data/detectors I need to get a satisfying result. Tobias Von: [email protected] <[email protected]> Im Auftrag von Jakob Erdmann Gesendet: Donnerstag, 27.

I am now wondering what is the best way to get the data into the model to make the demand in SUMO as realistic as possible. Based on the sumo documentation about demand modeling from count data flowrouter sounds like a good idea. But I’m missing the information about average speed of the vehicles detected in the time span in my data. I saw the SUMO scenario of Bologna from the SUMO Conference 2014 “Traffic simulation for all: a real world traffic scenario from the city of Bologna” (https://elib.dlr.de/89354/1/SUMO2014_scenarios.pdf) where the basic situation in case of demand data is the same. Only count data from induction loops and no speed information. Apparently the paper does not described which tools are used and how the missing speed information is handled. Now my questions: 1. Since I’m missing the speed information from the traffic data. How important is that speed value and how does this speed information affect the routes coming from flowrouter? 2. Do you have any references or experience for demand modeling with induction loop data which could help me to decide which tool is the best choice?
