SSDA helps the designer / engineer analyse "through visibility or line of sight" reports produced by MX, 12d and other 3d modelling packages.
Following the successful presentation of SSDA at the Australian MX User conference - Melbourne 2012, we are proud to announce the release of the upgraded SSDA (v1.0.0.2).
Current Features:
Load raw MX and 12d sight reports to review both car and truck vehicle types
Merge 12d rpt and level files without prior editing or the need to change the direction of rpt file to match the level file
Assign correct level information to the all chainage values
Save merged files for later use
Instantly apply grade correction to Austroads current guidelines
Review all loaded data and relative grades with ease
Apply user defined parameters for greater accuracy
Efficiently review data with clean and well presented charts
Review achieved sight distance against designed horizontal and vertical alignments, various design speeds, coefficient of deceleration, reaction time and record of initial report file
Customise chart grid for a closer review of your design
Tooltips added to chart to display exact sight distance at a given chainage
Tooltips have also been utilised in place of user manuals
Confirmation of eye and target heights applied to charts to avoid confusion during the review process
Chart outputs can be quickly printed straight to your default printer or jpeg for easy insertion into reports / presentation materials
Features being developed / revised:
Advance design analsysis
Inclusion of OSRoads and other guidelines
Conversion of metric to imperial units
User defined intervals, currently set to read sight reports at 5m
Most of the requests from the 2012 MX User conference (Melbourne, Australia) have been added however some require further development

Formula behind SSDA:
Stopping sight distance is a fundamental design criteria for both the transport and mining industries and is calculated by adding the distance travelled by a vehicle during the time it takes to react to and break before a hazard.
This can be calculated by: SSD = d1 + d2
where:
d1 (reaction distance) =
RT.V
3.6
d2 (braking distance) =
v2
254(F1+0.01G)
RT = reaction time (sec); V = operating speed (km/h); F1 = longitudinal friction factor; G = longitudinal grade;
(%, + for upgrades and – for downgrades)
Feedback:
While SSDA ticks my boxes to review MX and 12d files, it may not completely meet yours. If not, please do not hesitate to get in touch via the Contact us page and I will be more than happy to look into adding other features if there is sufficient demand.
