Isahgenius is a series of spreadsheets created to assist Road Traffic Accident Investigators. It was written by an Accident Investigator for Accident Investigators. Isahgenius is designed to assist with calculations, conversions and problems likely to be encountered in accident reconstruction. Containing over 60 formulas and combinations of formulas Isahgenius is set out in such a way that the user can quickly perform a whole range of calculations the results of which can be readily printed or copied into a Windows based word processor document. Isahgenius can perform complicated calculations in seconds. Unlike other programs,
Isahgenius allows users to view and consider a whole range of answers.
Isahgenius uses the power of the host program to perform the calculations and provide functionality. The Microsoft Excel and Lotus 123 versions consist of a workbook containing 12 worksheets named Speed, Distance, Time etc. Each worksheet consists of a series of tables, the user just enters the known values into the input cells and the calculations are performed instantly. One of the values is ranged so that the user is presented with several answers according to the ranged value. By pasting the table onto another sheet, any chosen value can be ranged using the power of the host program to perform the calculations and provide functionality. There are a number of features that differentiate Isahgenius from all other A.I calculation packages. Firstly, from the data supplied, it will calculate all possible answers. Thus, you may wish to calculate the distance taken to accelerate from one speed to another when the rate of acceleration is known. Isahgenius will do this but it will also tell you the time taken to complete this manoeuvre. By default, the calculation is repeated 8 times, according to the variable, so you get 16 answers for just one input. Another feature is that it contains a combination of formulas so that more complicated problems are easier to solve. For instance it will quickly calculate the safe speed in order to stop in a given distance (combining reaction distance with braking distance). Of course it will also tell you the total time taken to complete this manoeuvre. The third feature is problem solving formulas which consider the relative movement of two vehicles. For instance it will tell you, for given parameters, the distance it would take one vehicle to overtake another, assuming either a constant speed, or constant acceleration for the overtaking vehicle. These sort of problems can be very time consuming to solve with a calculator but Isahgenius will solve them instantly, and in this case will give you seven answers, according to the ranged value. However, remember that Isahgenius will calculate all possible answers from the data supplied. So, in the constant acceleration problem above, Isahgenius will also tell you the terminal speed and the time taken for the overtaking manoeuvre, for each of the seven scenarios! It is important to realise that Isahgenius is not a stand-alone product, it needs a host application in which to run. You must have one of the programs listed.
