Inaccuracy in active travel isochrones

Did any one found any inaccuracy in the active travel (walking and cycling) isochrones? If yes could you please let me know what kind of inaccuracy.It would be a great help for my research thank you

Hi @Nisha,

please be aware that before doing accuracy checks for travel times with isochrones, you might want to make sure you use the smoothing parameter and set it to 0 to get the highest possible geometric accuracy. By default isochrones are simplified a bit to reduce complexity.
Se smoothing parameter info:

Can you guide me in detail from where I have to start to check accuracy I am new to this
