Network Analysis Elements

After Location Allocation is chosen, the four related network analysis elements (Facility, demand, Point barrier, line barrier and polygon barrier) will be revealed on Network Location Window in the left side. Now we are to introduce the network analysis elements and the parameters.

Facility

It saves the network positions of the facilities. This layer contains two different symbols: the located facility and unlocated facility. Users can change the color and style of the Facilities layer in Layers in the right side, or set the related parameters on Network Location Window in the left side.

Facility Parameters

Parameter	Description
Name	The name of the facility.
Position	The coordinates of the facility.
Range	Sets the range (distance or time) to search the service area, which can be switched by cost type. The default Range is 3000, if you cannot get the result, this might be no result was found in this default range. We suggest you to modify the Range to fit your demand. The unit is second or meter, you can set in Analysis Settings > Cost Type >Time or Distance.

Demand

The network locations that require each facility in Location Allocation. Like the location of the incident, the site to load the goods and the source of the customer. Users can change the color and style of the Demands layer in Layers in the right side, or set the related parameters on Network Location Window in the left side.

Demand Parameters

Parameter	Description
Name	The name of the demand.
Position	The coordinates of the demand.
Found Facilities Count	After solved, the count of the facility that was found.
Range	Sets the range (distance or time) that a demand searches the service area, which can be switched by cost type. The default Range is 3000, if you cannot get the result, this might be no result was found in this default range. We suggest you to modify the Range to fit your demand. The unit is second or meter, you can set in Analysis Settings > Cost Type >Time or Distance.

Point Barrier, Line Barrier, Polygon Barrier

It stops or changes the accessibility of network data. This layer contains two different symbols: the located point barrier, unlocated point barrier, line barrier and polygon barrier. Users can change the color and style of the Barriers layer in Layers in the right side, or set the related parameters on Network Location window in the left side.

Point Barrier Parameters

Parameter	Description
Name	The name of point barrier.
Position	The coordinates of the point barrier.
CurbApproach	The accessibility of vehicle that will be influenced by the barrier. 1.0 represents vehicles in both forward and backward lanes will be influenced. 2.1 represents the position of barrier influences those in the digitizing direction(if the digitizing direction is equal to the road direction, we can consider the barrier influences vehicles in the forward lane. ) 3.2 represents the position of barrier influences those in the reversed digitizing direction(if the digitizing direction is equal to the road direction, we can consider the barrier is located in the backward lane. )

Parameter

Description

Name

The name of point barrier.

Position

The coordinates of the point barrier.

CurbApproach

The accessibility of vehicle that will be influenced by the barrier.

1.0 represents vehicles in both forward and backward lanes will be influenced.

2.1 represents the position of barrier influences those in the digitizing direction(if the digitizing direction is equal to the road direction, we can consider the barrier influences vehicles in the forward lane. )

3.2 represents the position of barrier influences those in the reversed digitizing direction(if the digitizing direction is equal to the road direction, we can consider the barrier is located in the backward lane. )

Polyline Barrier Parameter

Parameter	Description
Name	The name of line barrier.

Polygon Barrier Parameter

Parameter	Description
Name	The name of polygon barrier.
