TAZ generation problem #49

Open nudtdyk opened 1 year ago

nudtdyk commented 1 year ago

Hi, recently I am using SAGA to generate a traffic simulation for a certain area in Changsha city, China. But I found some problems with the TAZ extracted from inside OSM, so I deleted the abnormal TAZ and related buildings and weights, and then re-executed the later steps. Here are the problems I found throughout the simulation: 1、Taxi scale size can not be modified, the default is 10 2、Regenerating the OD matrix after modifying TAZ and generating activities will generate an error.

Without a way to reproduce it, I don't know how to help. I need more details and files.

As you can see, I set the parameters based on the population size and density of a certain area in Changsha and turned on the simulation. 步骤一 However, when the simulation proceeds to the seventh or eighth step an error starts to occur, as shown below: 步骤三 There is no reasonable route generation. In addition, there are some issues with TAZ generation and parking for taxi, as shown below: taz错误

taxi I'm guessing that these two issues could be the reason for the subsequent error generation, since TAZ for Changsha City is clearly larger than the size of the area I chose, and there are TAZs generated for other cities. Secondly, the parking area for taxi is too small and has too little capacity

Also, there seems to be some problems with the generateTaxiStandsFromOSM.py file, I've found that it always generates only one taxi parking space, which doesn't really match the reality of the situation either
