a.
Draw trajectories of approximately 8 to 11 vehicles moving on a one way 1-lane road with
different time-varying speeds.
b. Consider a time-space window in the time-space diagram of part (a). See below. Denote
the number of vehicles passing BD, DC, AC, and AB respectively as n1, N2, N3, and n4. Write
an equation relating n₁, N2, N3, and n4 to each other. What is the physical intuition of this

Consider a city center where the traffic conditions are described by a Macroscopic
Fundamental Diagram (MFD) of network outflow (g- rate of trips finished) vs. accumulation (n-
number of cars) with a trapezoidal shape, as shown in the figure below. The values of the
parameters are:
•
•
maximum trip completion rate gmax=100 [veh/min]
critical accumulations ncr1=1000 [veh] and ncr2=1500 [veh]
jam accumulation njam=4000 [veh].

There are two types of demands in the morning peak hour (7-8am): trips generated from
outside the city center with rate q1=80 [veh/min], and trips generated from within the city
center with rate q2=50 [veh/min]. In addition, a perimeter traffic control, u, is available that
only restricts vehicles entering the city from outside.
If at 7am there are already no=500 [veh] in the city center:
a. Write the dynamic equations (mass conservation equation) in a continuous form for the
center of the city.
b. Convert the continuous dynamic into the discrete…
