Most of the information received by a driver is provided by road signs and markings, especially in low visibility conditions and at night. While road markings mainly show the boundaries of the road, traffic signs inform, indicate, forbid, oblige, orientate and warn of risks and dangers. This paper describes a method for dynamically measuring traffic sign luminance as perceived by the driver of a typical European car on an empty and unlit road, without causing discomfort to other drivers on the road.

respectively. 155±16 s, 221±12 s and 240±6 s were needed to achieve complete thawing of 250 mL bags filled at 30, 40 and 50 mL, respectively. For a type of bag, decreasing volumes thawed faster, but 50 mL bags filled at 20 mL took longer to thaw than 250 mL bags filled at 30 mL (different spatial conformation and specific surfaces). Delivery of thawed bags from the pharmacy to the transplant unit was done in 4.5±0.21 min. Conclusion and relevanceThawing duration may vary by twice a function of volume. Mean lengths provide an optimal organisation in a circuit where every minute must be taken into account. A total thawing-addressing time rate of between 6.5 and 8.5 min means that the nursing team has almost 20 min to administer tisagenlecleucel.
