Scenarios

Scenarios

This page contains a list of scenarios we expect our simulator to handle. There will help us identify the relevant objects and uncertainties to consider.

Scenario 1:

• 30 cars
• 55 intersections, laid out in a triangle similar to a tree, with the top row having one intersection and the last row having 10. Each intersection is connected to all surrounding intersections, up to 6
• 10 randomly distributed accidents, 5 on roads, 5 at intersections
• Posted speed limit of 60 mph on all roads, real speed limit decreases by 5 mph for every additional car on the edge
• Single lane roads, no passing

Scenario 2:

• 1000 cars
• 500 intersections, laid in a 20 x 25 grid
• Multiple lanes on each edge so passing is allowed
• Whenever more than 5 cars are on any particular edge, an accident occurs
• Speed limit is 50mph, however there is a minimum speed of 40mph

Scenario 3:

• 500 cars
• 400 intersections, 20 x 20 grid
• All streets except for the outer edge streets are one way
• One way streets are one lane so no passing, outer edges have multiple lanes so passing is allowed
• Accidents can occur at any intersection with 3 or more cars with 1/500 probability
• Speed limit on one way streets is 40mph, with the real limit decreasing by some amount for additional cars
• Outer edges have a limit of 70mph, there are enough lanes to handle all traffic

Scenario 4:

• 500-1000 cars

• a big grid of roads (say 25x25 or even larger) and an overlay of express routes with a few turnoffs

• normal roads have low speed limits (say 30), express routes have high speed limits and higher traffic capacity

• no passing on normal roads

• high traffic penalty on normal roads is greater than on express routes

• add in a bunch of accidents with a probability depending on traffic density)

Scenario 5:

• 2 cars
• 16 intersections, 4x4 grid
• Both start in the upper left corner, have a destination of the bottom right corner
• All roads have posted speed limit of 40 mph, but 2 cars on an edge lowers speed limit to 30 mph
• All roads are 2 way, but no passing
• Car 2 starts moving right after Car 1
• No accidents

Scenario 6:

• 10 cars
• 100 intersections, 10x10 grid
• Each car starts at a different spot on the top row, and their destination is the mirror location on the bottom row
• Passing allowed on horizontal streets, not on vertical streets
• Any intersection with 2 or more cars has a 1/500 chance of an accident occurring
• Constant speed limit of 50 mph on horizontal streets, starts at 50 mph and goes down by 5 mph with each additional car on vertical streets

Scenario 7:

• 50 cars, half are trucks that are double the length of normal cars
• 100 intersections, 10x10 grid
• Random start and end points for each car
• All roads have passing lanes, but trucks cannot be passed or pass other cars
• Speed limit of 60mph, decreases by some function with additional load, trucks decrease speed faster than cars
• No accidents
