prameshk / traffic-assignment Goto Github PK

hello i've been trying to use your code for a project to find user-equilibrium answers from a network i downloaded from osmnx using pyrosm but your code gives the following error:

Traceback (most recent call last):
File "C:\Users\Mohammad\PycharmProjects\importing network\ta.py", line 409, in
assignment("deterministic", "FW", accuracy = 0.001, maxIter=1000)
File "C:\Users\Mohammad\PycharmProjects\importing network\ta.py", line 366, in assignment
SPTT, x_bar = loadAON()
File "C:\Users\Mohammad\PycharmProjects\importing network\ta.py", line 232, in loadAON
SPTT = SPTT + nodeSet[s].label * dem
KeyError: '5414342274.0'

can you help me find out what is the problem and how should i fix it ?
thanks

i wonder how do i create a tntp file, use what software, transcad? or just using txt file and name the suffix with .tntp?
and also, when running datapreparation with tntps download from [bstabler TransportationNetworks], it reports an error:

`element_no, element_value = element.split(":") # get our pair
28 # beware, these two are now most likely padded strings!
29 # that's why we'll strip them from whitespace and convert to integer/float

ValueError: not enough values to unpack (expected 2, got 1)
`

Sorry to bother you!
I find a problem about traffic assignment by fw algorithm:
The program will not throw any errors when there is no feasible path between the start and end nodes. May you please check out this problem?
Thanks!
