Please describe and explain the steps to be taken to fulfil this task.List six transportation simulation models or software systems described in the Highway Capacity Manual 2000 or elsewhere and elaborate on five (5) of these models/software systems.HIKI TO D OSHITENOJ ON DE No. Date 3 A parking facility operates from 8 a.m. to 6p.m, whereby 20% of those who wish to park are turned back daily because of lack of space. A total of 200. vehicles are able to park daily of which 60% park for an average parking duration of 9 hours and the remaining park For an average parking duration of 2 hours. From a survey of the vehicles who are not able to park daily it is known that 20% of these vehicles desire to park for 9 hours and the For 2 hours. remaining desire to Park If the parking efficiency is 0.9, determine: Li) the number of additional space hours required? (ii) the additional number of parking bays required in order to meet excess demand?
