SiWIMD contains several tools for evaluating and presenting results of the measurements. It:

	counts single, double, triple and other axles,
	calculates ESAL values for single, double and triple axles,
	calculates overloading for gross weights, single, double and triple axles,
	calculates histograms of single, double and triple axles,
	calculates histograms of gross vehicle weights based on vehicle category,
	calculates time histograms based on vehicle category,
	simulates expected maximum load effects on short span bridges (optional).

Calculation of ESAL values and overloading

Overloading module applies specified axle loads limits for gross weights as well as for single, double and triple axles and calculates total loading and overloading for all vehicles (axles) in the database. Calculation is done for 2 parameters:

	number of vehicles and axles respectively
	ESAL (Equivalent Single Axle Loads)

Overloading is presented as the difference between the cumulative ESAL value of all overloaded axles and the same axles at their legal limit loads (for example, overloading of a 19,4 ton axle is calculated as the difference between the ESAL value of a 19,4 ton axle and a legally loaded 18,0 ton axle)

SiWIMD also calculates relative overloading of all vehicles in the database (gross weights and axle spacings).

Histograms of single, double and triple axles

Overloading module also calculates histograms of single, double and triple axles, for individual days or in total. Results can be exported into a text file or pasted directly into MS Excel (data) or any other program (picture).

Gross weight histograms

Histogram module calculates histograms of gross weights for individual categories of vehicles, as specified in Calculate histograms window. Results can be exported into a text file or pasted directly into MS Excel (data) or any other program (picture).

Time histograms

Histogram module also calculates histograms of gross weights for individual categories of vehicles, as specified in Calculate histograms window, as a function of hours during a day. Results can be exported into a text file or pasted directly to MS Excel (data) or any other program (picture).

Expected maximum traffic loading on bridges

Bridge module (optional) calculates the expected maximum load effects of traffic on short and medium span bridges (with spans below 50 meters, where governing load case is due to 2 vehicles positioned side by side on the bridge). Results can be exported into a text file or pasted directly into MS Excel (data) or any other program (picture).
