Road Network Settings

This form allows you to maintain the road network needed by the Haulage Analysis or the Optimization option in DTS Blend.

Field	Description
Node 1	The node at which the road segment starts. The node is created if it does not exist.
Node 2	The node at which the road segment ends. The node is created if it does not exist.
Distance	The distance between the two nodes. If the segment represents a curved section of road, this value must be the distance on the road between the nodes - not the straight line distance.
Elevation	The elevation between the two nodes. This must be in the same dimensions as the distance (e.g. metres, feet).
Bidirectional	Specifies if the road segment can be used in both directions.
Pantograph	Specifies if a pantograph is available on the road segment
Rolling Resistance	The rolling resistance coefficient (in %) for the road segment. This is the percentage of the weight (applied at 90o) that is used as the force resisting the movement of a truck on the section. The default value is 3%.
Entry Angle	The entry angle (in degrees) of the road segment at node 1. This is the angle of the road segment in the horizontal plane at the entry point at node 1.
Exit Angle	The exit angle (in degrees) of the road segment at node 2. This is the in plane angle of the road segment at the exit point at node 2
T12 Empty	The average travel time (in seconds) for empty trucks moving from node 1 to node 2. If the value is 0, the system estimates the time from rim-pull curves, road gradient, etc.
T12 Full	The average travel time (in seconds) for fully loaded trucks moving from node 1 to node 2. If the value is set to 0, the system estimates the time from rim-pull curves, road gradient, etc.
T21 Empty	The average travel time (in seconds) for empty trucks moving from node 2 to node 1. If the value is 0, the system estimates the time from rim-pull curves, road gradient, etc.
T21 Full	The average travel time (in seconds) for fully loaded trucks moving from node 2 to node 1. If the value is set to 0, the system estimates the time from rim-pull curves, road gradient, etc.
Max Speed 12	The absolute maximum speed (in km/h) allowed on the road segment travelling from 1 to 2. Additional limitations can be set in the definition of haulage resources.
Max Speed 21	The absolute maximum speed (in km/h) allowed on the road segment travelling from 2 to 1. Additional limitations can be set in the definition of haulage resources.
Sign at Exit 1	The type of road sign encountered when leaving the segment at node 1 (None, Yield, Stop Type 1, Stop Type 2, Stop Type 3). The speed going through the yield sign as well as the delay at the different types of stop sign are specified in the haulage resource definition.
Sign at Exit 2	The type of road sign encountered when leaving the segment at node 2 (None, Yield, Stop Type 1, Stop Type 2, Stop Type 3). The speed going through the yield sign as well as the delay at the different types of stop sign are specified in the haulage resource definition.
