ENG 412 Roads and Traffic Engineering Assignment 1 Due date – Friday 26 April 2019 Note. If any plagiarism detected, you will get zero marks. Question 1 Discuss Model Calibration and Validation in Traffic Simulation for three softwares (SIDRA, Aimsun andVissim) . Explain what measures you would undertake to calibrate and validate a model. Question 2 Using the information in Tables 1 and 2 use the gravity model to assign trips from nodes A, B, and C to nodes D and E. Then conduct row and column factoring until your estimated productions and attractions are within a 3% of the observed values. Your answer should be in the form of an origin-destination matrix with each value rounded to the nearest integer.
