Each Vehicle is an assembly of almost 40 to 45 subsystems like brakes, steering, seating, powertrain, exhaust, etc. When all these aggregates or subsystems are sandwiched in to a Monocoque body shell (BIW) it forms a vehicle. Different type of vehicle is designed for different applications, Cars designed for Comfort & Safety whereas, commercial vehicles are designed for Load carrying capacities & durability. Vans are designed for all of these aspects and treated as MUV (Multi utility vehicles).

Such a reactions subject the drivers physically & mentally. There are almost 2250 critical parameters, which need to be evaluated for each van class vehicle. All these vehicle parameters categorized into effort related parameters, Ambiance related parameters (Noise, Visionary field), Road induced vibration related parameters, Ergonomic parameters & Government regulations. Van design parameters must be within the limit, in order to ensure Driver's stresses & ultimately Driver's fatigue within the limits. As per the Company market survey Van class drivers are subjected to rough roads & higher speeds for Ambulance kind of application, whereas intermittent city people pickup for mini bus type of applications. Driver's Physical fatigue is the transient inability of a muscle to maintain optimal physical performance. This project is an attempt to evaluate most critical Van parameters, which directly affect the Driver's Physical & Psychological Fatigue.
