[Vehicle Pool]
// A list of 20 vehicle models that comprise the 'vehicle pool' which Traffic Flow will
// randomly select 3 vehicles from every 15 seconds to load into the game's memory.

// NOTE: You can find a list of valid vehicle model names by using SparkIV to look
// inside the vehicles.img file in pc/models.  It probably is possible to use ped
// models here too, but it could lead to whole areas becoming full of one type of ped.

// SECOND NOTE: Traffic Flow doesn't actually spawn these vehicles, it only loads them
// into the game's memory which affects the way that the game spawns vehicles in general
// therefore vehicles which don't normally spawn on the streets such as the NOOSE cruiser
// still will not spawn, even if all 20 slots are occupied by it.  Instead, when you get
// 4 wanted stars, you will be pursued by more NOOSE cars than you could ever imagine.

Model1 = ORACLE
Model2 = PREMIER
Model3 = SULTAN
Model4 = BUS
Model5 = FACTION
Model6 = SENTINEL
Model7 = PERENNIAL
Model8 = WASHINGTON

[Other]

// This variable controls how frequently emergency services will be dispatched throughout the city.
// The variable is represented in the code as a 1 in [variable] chance of a dispatch occuring,
// which happens every 15 seconds.  To increase the chance that a dispatch will happen, decrease
// the variable (do not go lower than 1), and to decrease the chance that a dispatch will happen,
// increase the variable (you shouldn't need to go any higher than 100).

// NOTE: The default value, 8, should provide for a balanced experience.  If you experience crashes
// which may be related to these dispatches, increase the variable.

ChanceOfRandomDispatch =8

// This variable controls how often TrafficFlow will update the game's memory as well as how often
// the script will perform the calculation to determine whether or not to create a random dispatch.
// If you are experiencing issues with TrafficFlow slowing down your game, or causing other performance
// related issues, set this variable higher.

// NOTE: This variable is in miliseconds (e.g. 1 second = 1000 ms), to have TrafficFlow tick every
// minute, set this variable to 60000.

TimerInterval = 15000


其中ChanceOfRandomDispatch 和TimerInterval = =。求翻译具体含义
