LITESTAR 4D Litecalc - Tunnel lighting is the program module for the management of the lighting installations in rectilinear road tunnels and includes the following functions:
- design and management of the tunnel through 2 modes:
- wizard (available with the Pro configuration under Licenses B and G)
- advanced (free) available with the Tunnel Plus module
- manual insertion of single luminaires or groups of luminaires
- definition of the tunnel section among 4 parametric types:
- rectangular
- vaulted
- elliptical
- circular
- import of objects in 3D (road signs, traffic barriers) from external files (3DS or OBJ format) or directly from the program library
- definition of special calculation areas through regular or irregular working planes
- definition of luminance values at the tunnel entrance using:
- Adrian diagram
- luminance value at the entrance
- free curve via Excel/CSV file
- calculation of parameters:
- horizontal, cylindrical, semi cylindrical and hemispheric illuminance
- luminance
- glare (fTI) with fixed and moving observer

Tunnel Plus
Litecalc Tunnel lighting can be integrated with the extra module Tunnel Plus that allows to determine the luminance curve at the entrance of a straight tunnel:
- Graphically through the Adrian's diagram or the L20 method
- Numerically by entering the luminance value at the access zone
- Tabularly by importing the chart of luminance values according to the progressive x
