Traffic Simulation Home assignment Ing. Ondřej Přibyl, Ph. D.

Assignment l To create a model for one lane of a highway segment – microsimulational, – Time triggered, – Stochastic model. l Use MS Excel! Time interval - 10 min, update every 1 sec l Make a statistical evaluation of 10 runs l You do not have to consider type of the segment (lane bright) l Consider only 30 vehicles to be moving along this segment l Course: Traffic Simulation Home assignment 2

Guidance It is a car following model 2. You should consider 1. Aggresivness of the drivers (for example: 70% normal, 30% aggressiv) 1. – The speed is computed based on the presence of the effect area from previous vehicle Initialization: l – All vehicles are split according to uniform distribution in the segment You need to compute in every step l – – Position in the segment Acceleration/deceleration Speed Distance to the previous vehicle Course: Traffic Simulation Home assignment 3

Expected results 1. Original data (MS Excel) 2. Document (MS Word) which describes all steps and results You should describe all difficulties as well 1. Speed 1. Average, standard deviation, … 2. Histogram 2. Density 1. Average, standard deviation, … 2. Histogram 3. Traffic flow 1. Average, standard deviation, … 2. Histogram Course: Traffic Simulation Home assignment 4
