By KPL, the reasonable WTP from motorcyclists is 726 bath perperson, the reasonable WTP from car users is 2,355 bath perperson and the average of sample groups the reasonable WTP equals to 1,540 bath perperson. The Value of Statistical Life (VSL) by CVM is 12.39 millions bath perperson. By KLP the reasonable VSL equals to 10.13 millions bath perperson.
