Global Configuration

Verified: February 2020 - TM:PE 11.0

Overview

The TMPE_GlobalConfig.xml contains numerous parameters, many of which are not shown in the mod settings UI. You can change these parameters to fine-tune TM:PE to your requirements.

You can find the file in the following path (may be different depending on where you installed the game):

C:\Program Files (x86)\Steam\steamapps\common\Cities_Skylines

The log file is split in to several sections as listed below:

• General Settings
• Debug (only in developer DEBUG builds)
• AdvancedVehicleAI
• DynamicLaneSelection
• Main
• Gameplay
• ParkingAI
• PathFinding
• PriorityRules
• TimedTrafficLights

Each section contains parameters relating to a specific ConfigData class within TM:PE.

Changing values

Default values shown are correct as of TM:PE v11.0-alpha6 (August 2019)

If editing the file, make sure you use a plain text editor, not a word processor. For more information, see: Text Editors

Note that TM:PE only performs basic type checking on values. If you specify invalid value types, or values outside the specified range, you will get errors.

General Settings

There are a few top-level keys containing general settings...

Parameter	Range Type Default	Notes
Version	1 → +∞ integer current	The config file format version number; increments whenever we make alterations to the format.
LanguageCode	AvailableLanguageCodes string game language	A two-letter ISO 639-1 code depicting the selected locale. If the key is not present, or the value empty, TM:PE will use whatever the base game language is set to.

Note: We also provide some support for non-standard language codes used by popular game translation mods; we transpose them in to ISO 639-1 equivalents. For more details see PR #534.

Debug

TODO: Update links

This section is only applicable to DEBUG builds of TM:PE and controls the output of debug logging to the TMPE.log file.

For more information, see:

• Build instructions
• Logging documentation

AdvancedVehicleAI

This section describes configuration parameters that are used by the Advanced Vehicle AI.

Parameter	Range Type Default	Notes
LaneRandomizationJunctionSel	1 → +∞ integer 3	At every nth junction (where n is the parameter value), the AI randomly selects a favorite lane for the vehicle that a path-calculation is being performed for.
LaneRandomizationCostFactor	0 → +∞ float 1	During lane selection randomization, the AI assigns this cost value to a lane with a probability of 50%. In the remaining 50%, a lane is not assigned any additional costs.
LaneChangingBaseMinCost	1 → +∞ float 1.1	Minimum cost factor, applied to path costs for every considered lane change.
LaneChangingBaseMaxCost	1 → +∞ float 1.5	Maximum cost factor, applied to path costs for every considered lane change.

MoreThanOneLaneChangingCostFactor	1 → +∞ float 2	Cost factor, applied to path costs for every considered multi-lane change.
TrafficCostFactor	0 → +∞ float 4	At every junction considered during path-finding, this cost factor is multiplied with the inverted (slightly randomized) mean speed of the current segment.
LaneDensityRandInterval	0 → 100 integer 20	Segment mean speeds that are queried during path-finding are randomized before multiplying with the set TrafficCostFactor. This value defines the zero-centered randomization interval (e.g. if the value is set to 20, it is equally likely that 10% are added to or subtracted from the current segment's relative mean speed).
MaxTrafficBuffer	1 → +∞ integer 10	Real-time traffic measurements collects mean speeds of up to n vehicles (where n is the parameter value). If the threshold is reached, collected mean speeds are forgotten and a fresh measurement cycle begins.

ParkingAI

This section describes configuration parameters that are used by the Parking AI.

Parameter	Range Type Default	Notes
ParkingSpacePositionRand	1 → +∞ integer 32	Randomization radius for manipulating the point where the search for available parking spaces starts. Randomization is performed to allow road-side parking spaces on the opposite site of the road to be considered during parking space search.
VicinityParkingSpaceSelectionRand	1 → +∞ integer 4	For every found candidate parking space, a random number between 0 and VicinityParkingSpaceSelectionRand - 1 is generated. If the drawn number is 0, the parking space is skipped. This procedure is applied in order to prevent vehicles from only selecting the closest parking space available.
MaxParkingAttempts	1 → +∞ float 10	Maximum number of parking attempts to perform. Vehicles despawn if the number of attempts exceeds this value.
MaxParkedCarInstanceSwitchSqrDistance	0 → +∞ float 6	Squared distance between a parked car and the pedestrian that enters the car, at which the car entering procedure is executed.
MaxBuildingToPedestrianLaneDistance	0 → +∞ float 96	Maximum allowed distance between building parking spaces and the nearest pedestrian lanes. Building parking spaces that are located too far away from pedestrian paths are not considered in order to prevent pedestrians from floating over long distances.
MaxParkedCarDistanceToHome	0 → +∞ float 256	Maximum acceptable distance between parked vehicles and their owner's home. If the parked vehicle is located further away from home than this value, car owners will be forced to use the car when returning home in order to relocate it to a position that lies closer.
MaxParkedCarDistanceToBuilding	0 → +∞ float 512	Maximum acceptable distance between parked vehicles and the current target building. If the distance between target building and source location is smaller than this value the owner citizen prefers to walk or to use public transportation to reach the target.
PublicTransportDemandIncrement	1 → +∞ integer 10	If a citizen is unable to reach a specific target building by means of walking, driving or public transport, the public transport demand of both the source and target buildings are increased by this value.
PublicTransportDemandWaitingIncrement	1 → +∞ integer 3	If the maximum acceptable time a citizen waits for a public transport vehicle to arrive at a stop (e.g. a bus stop) is exceeded, the citizen starts searching for alternative routes to the current target building and public transport demand of the target building is increased by this value.
PublicTransportDemandDecrement	1 → +∞ integer 1	Public transport demand associated with buildings is continuously diminished by this value.
PublicTransportDemandUsageDecrement	1 → +∞ integer 7	If a citizen succeeds in finding a path to a target building that includes using public tranportation, the public transport demand of both the source and target buildings are diminished by this value.
ParkingSpaceDemandDecrement	1 → +∞ integer 1	Parking space demand associated with buildings is continuously diminished by this value.
MinSpawnedCarParkingSpaceDemandDelta	-∞ → +∞ integer -5	When a parked car is spawned near the source building, parking space demand is either decreased or increased, depending on the distance between the parked car and the source building. This value reflects the maximum penalty or minimum reward used for modifying the demand value.
MaxSpawnedCarParkingSpaceDemandDelta	-∞ → +∞ integer 3	As above. This value reflects the minimum penalty or maximum reward used for modifying the demand value.
MinFoundParkPosParkingSpaceDemandDelta	-∞ → +∞ integer -5	When a parking space is found near the target building, the parking space demand is either decreased or increased, depending on the distance between the parked car and the target building. This value reflects the maximum penalty or minimum reward used for modifying the demand value.
MaxFoundParkPosParkingSpaceDemandDelta	-∞ → +∞ integer 3	As above. This value reflects the minimum penalty or maximum reward used for modifying the demand value.
FailedParkingSpaceDemandIncrement	1 → +∞ integer 5	If no parking space can be found near the target building, the parking space demand is increased by this value.
FailedSpawnParkingSpaceDemandIncrement	1 → +∞ integer 10	If no parking space can be found near the source building, the parking space demand is increased by this value.

PathFinding

This section describes configuration parameters that are used by the modified path-finding algorithm.

Parameter	Range Type Default	Notes
PublicTransportLanePenalty	1 → +∞ float 10	Represents the cost multiplier that is used to keep regular traffic away from transport lanes (see Bus lane reservation).
PublicTransportLaneReward	0 → 1 float 0.1	Represents the (inverted) cost multiplier that is used to keep public transport on the respective transport lanes (see Bus lane reservation).
HeavyVehicleMaxInnerLanePenalty	0 → +∞ float 0.5	Represents the maximum cost multiplier that is used to keep heavy vehicles away from inner lanes on highways (see Heavy trucks prefer outer lanes on highways).
HeavyVehicleInnerLanePenaltySegmentSel	1 → +∞ integer 3	Randomization value that controls the ratio of segments where the inner lane penalty is applied for heavy vehicles.
IncompatibleLaneDistance	0 → +∞ integer 2	Represents the cost factor that is applied to lane changes that are normally not allowed due to incompatible lane arrow configurations. It is used to advice busses to use compatible lanes even if they are allowed to ignore lane arrows (see Busses may ignore lane arrows).
UturnLaneDistance	0 → +∞ integer 2	Represents the cost factor that is applied to u-turns. It is used to minimize the number of performed u-turns (only relevant, if the option Vehicles may do u-turns at junctions is activated)
MaxWalkingDistance	0 → +∞ float 2500	Represents the maximum walking distance, in meters (base game default: 1000). For reference, a zoning square ("cell") is 8 meters.
PublicTransportTransitionMinPenalty	0 → +∞ float 0	Minimum penalty applied to path costs whenever a cim switches between different public transport lines.
PublicTransportTransitionMaxPenalty	0 → +∞ float 100	Maximum penalty applied to path costs whenever a cim switches between different public transport lines.

PriorityRules

This section describes configuration parameters that are used for Priority Signs.

Parameter	Range Type Default	Notes
MaxPriorityCheckSqrDist	0 → +∞ float 225	Maximum squared distance between other vehicles and the junction center point. If the vehicle is yet further away from the junction, it is not considered as a possibly conflicting vehicle.
MaxPriorityApproachTime	0 → +∞ float 15	Maximum junction approach time difference between queried vehicle and other vehicles. If two vehicles will reach a junction at completely different moments priority rule checking is skipped for them.
MaxPriorityWaitTime	0 → +∞ integer 100	Maximum waiting time in front of yield/stop signs. If the waiting time exceeds this value, priority rule checking is temporarily disabled for the vehicle in question.
MaxYieldVelocity	> 0.0 → +∞ float 2.5	Maximum vehicle velocity when approaching a Yield sign. See note below table for how to convert to/from km/h.
MaxStopVelocity	> 0.0 → +∞ float 0.1	Maximum vehicle velocity when approaching a Stop sign. See note below table for how to convert to/from km/h.

The MaxYieldVelocity and MaxStopVelocity can be converted to km/h by multiplying their value by 8. For example, if the specified velocity was 2.5 then that equates to 2.5 * 8 which is 20 km/h. If you want to convert km/h value in to velocity value, just divide the km/h by 8.

EDIT: On further investigation it looks like the value above might be 5 (ish) instead of 8; we need to do more digging in to the code to find out for sure.

TimedTrafficLights

This section describes configuration parameters that are used by Timed Traffic Lights.

Parameter	Range Type Default	Notes
FlowWaitCalcMode	FlowWaitCalcMode enumeration Mean	Vehicle counting method to use. Mean: The average number of waiting/driving vehicles is being used as for comparison. Total: The sum of all waiting/driving vehicles is being used for comparison.
FlowToWaitRatio	0 → +∞ float 0.8	Default traffic light sensitivity.
SmoothingFactor	0 → 1 float 0.1	Smoothing factor for updating the number of waiting/driving vehicles. Used to prevent counting spikes from happening during adaptive traffic light phases. For every vehicle counting, the previous number of waiting/driving vehicles is multiplied with the smoothing factor. The current number of waiting/driving vehicles is then multiplied with 1 - SmoothingFactor and finally added to the result.
