Units

Select the units of measurement which match your site coordinate system and local standards.

Use the Quick Set drop-down to select Metric or Imperial units of measurement.

Scripting

 

Use Extensions

Select the Use Extensions option to enable custom scripts.

Contact your Alastri support representative for assistance with Site Specific Extensions.

Settings (Top)

Join Mode

Automatically Use Segment Names to Choose Joins

Toggle to use “Assign Joins Based on Segment Names” function by default.

If enabled, running extension “Assign Joins Based on Segment Names” after updating blocks to road connection will become unnecessary and disabled.

Bench/Lift Settings

Bench / Lift Settings control the travel parameters between a block and the network.

Rolling Resistance

Rolling resistance used for on bench travel.

Active Work Area Speed Limit

Speed limit as the truck pulls away from the digger.

Active Work Area Radius

Distance to maintain the Active Work Area speed limit.

Access Road Speed Limit

Speed limit as the truck exits the Active Work Area.

Access Road Length

Distance to maintain the Access Road speed limit.

Main Road Speed Limit

Speed limit between the Access Road and the Network.

Auto Join Distance

Allowable air gap when pathfinding from the bench to nearby ramps.

Disable Bench / Lift Pathfinding

This is how a truck works out how to drive on the bench to arrive at a designed haul route. If Bench Pathfinding is Disabled, trucks will fly across a void.

Max Block Pathfinding Grade (%)

Forces the pathfinding to honour a maximum rise/run gradient.

Settings (Top)

Acceleration

Max acceleration (km/h/s)

Maximum "kilometers per hour per second" that a reasonable operator applies to the truck for acceleration.

Max Unloaded Deceleration (km/h/s)

Maximum "kilometers per hour per second" that a reasonable operator applies to the truck to decelerate, for a truck without load.

Max Unloaded Forced Deceleration (km/h/s)

Maximum "kilometers per hour per second" that a reasonable operator applies to force an unloaded truck to decelerate.

Max Loaded Deceleration (km/h/s)

Maximum "kilometers per hour per second" that a reasonable operator applies to the loaded truck for deceleration.

Max Loaded Forced Deceleration (km/h/s)

Maximum "kilometers per hour per second" that a reasonable operator applies to force a loaded truck to decelerate.

Traction

Coefficient of Traction

Used in determining the maximum amount of rimpull that can be exerted without the tyre spinning.

Braking Reliance on Traction

Used to calculate the maximum force that can be applied to the road without skidding.

Settings (Top)

Retarder

Use Retarder Speed Limit

Stops trucks from exceeding their OEM retard curve.

Max Use of Retarder

Used in determining what speed a truck must reach before it can be controlled by the retarder.

It is a percentage of the total braking force that the retarder can contribute.

For example, if you require 5000 kg/f of braking force to descend a segment safely and your maximum retarder utilization is set to 0.5, then the retarder can safely bring the truck to a stop at whatever speed the curve indicates when the braking force reaches 2500 kg/f.

This parameter is used to determine the maximum safe speed at which the retarder can decelerate the truck, which can impact the truck's speed limit. It is also used to validate whether a truck model can safely navigate worst-case segments when the specified setup is in use.

Calculation Precision

Accuracy

Only to be changed by Alastri staff. Controls the number of iterations in numerical integration.

Zero Acceleration Tolerance

Only to be changed by Alastri staff. Controls rounding in acceleration calculations.

Settings (Top)

Transfer Speeds

Transfer speeds are the speeds at which a truck enters onto and exits from the road network.

To allow trucks to use the signposted speed limits to traverse from autojoins to the network, rather than coming to a full stop, the Transfer speed shouldn’t be zero.

Entrance Speed Unloaded

Maximum unloaded entry speed to the network from the ramp (other speed limits also apply).

Entrance Speed Loaded

Maximum loaded entry speed to the network from the ramp (other speed limits also apply).

Exit Speed Unloaded

Maximum unloaded exit speed to the network from the ramp (other speed limits also apply).

Exit Speed Loaded

Maximum loaded exit speed to the network from the ramp (other speed limits also apply).

Terminal Speeds

Terminal speeds are the speeds at which a truck arrives at and exits from a node. In almost all projects this should be set to zero, since trucks slow to a stop at the digger and at the dump.

Arrival Speed Unloaded

Final arrival speed at digger. Usually zero (could be non-zero if cruising into Spot At Loader).

Arrival Speed Loaded

Final arrival speed at dump. Usually zero (could be non-zero if cruising into Spot At Dump).

Departure Speed Unloaded

Starting departure speed from dump. Should always be zero.

Departure Speed Loaded

Starting departure speed from digger. Should always be zero.

Settings (Top)

Corners

Corner Lookahead Distance

The arc distance used to calculate the angle of deviation for cornering speeds.

Path Finding

Try Return on Same Route

Forces trucks to return the way they came, even if there is a faster alternative route, while honouring road signs.

Advanced

Various cache settings

Only to be changed by Alastri staff.

Electrical Infrastructure

Electrical Network Settings

This setting can be ticked on to enable electrical network support. This includes cables and substations.

Calibration

Use Calibration For Pathfinding

Turn on to use Calibrated haul times when performing path finding. If this is turned off, there could be differences between the actual haul path and the predicted haul path.
