The design criteria are the nominal values for the design parameters to obtain a vehicle with good crashworthiness. A group of 8 vans with different mass and brand, are selected from the crash test database of the National Highway Traffic Safety Administration (NHTSA). These vans which were manufactured between 2012 and 2017, earned four or five star rating in full-width rigid barrier (FWRB) frontal impact test. The values of the design parameters are statistically analysed and the corresponding design criteria and restraint performance are specified. Acceleration-based injury risk parameters and restraint performance metrics are defined. This paper presents design guidelines for a van with good crashworthiness and low injury risk which can be useful in the preliminary design of a van.
