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

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

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

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

5. Home assignmentCourse: Traffic Simulation 5 Discussion What are the main inputs (effects) to affect your vehicle position?
