Introduction
This manual describes the "ROAD+"
program of the TPS1100
Professional Series.
The program uses the station and
offset method to control contsruction
staking of roads and other types of
curvilinear projects. The program
supports station equations, cross
section assignment by station, cross
section definition, cross section
interpolation, automatic
superelevation and widening, and
slope staking/catch points.

Alignment Definition
An alignment consists of three basic
components which are horizontal
alignment, vertical alignment and
cross-section template. Of these, a
horizontal alignment is mandatory to
use "ROAD+". All other alignment
elements are optional.
"ROAD+" reads the elements of each
of these components from data files
that are in GSI file format. In addition,
a file can be created for entering
cross-section stations for specific
locations such as points needed for
the staking of superelevation points.
If station equations are needed,
"ROAD+" will read a file created for
station equations and apply the
appropriate corrections.
Data Files
Each of the data files "ROAD+" reads
contain the necessary information
specific to the component being
defined. The files have unique
identifiers and must be in the GSI file
format:
Horizontal
Alignment File ....... ALN?????.GSI
Vertical
Alignment File ........ PRF?????.GSI
Template File ........ CRS?????.GSI
Cross-section
Assignment File ..... STA?????.GSI
Station
Equation File ......... EQN?????.GSI
The three letter prefix, ALN, PRF,
CRS, STA and EQN identify the type
of file and must be used when
creating the data files. The ? can be
any valid DOS character. The file
extension GSI defines the file as a
GSI file and must be used.
