A four-arm uncontrolled un-signaled urban intersection of both-way traffic is illustrated in the figure. Vehicles approaching the intersection from the directions A, B, C, and D can move to either left, right, or continue in straight direction. No U-turn is allowed. In the given situation, the maximum number of vehicular crossing conflict points for this intersection is _________ (answer in integer)
Match the items in Group-I with the most appropriate stages of travel demand modelling in Group-II.
\[\begin{array}{|c|c|} \hline \textbf{Group I} & \textbf{Group II} \\ \hline (P)\ \text{US-EPA's MOVES} & (1)\ \text{Trip Assignment} \\ (Q)\ \text{Fratar Model} & (2)\ \text{Trip Production} \\ (R)\ \text{Growth Factor Model} & (3)\ \text{Trip Distribution} \\ (S)\ \text{User Equilibrium} & (4)\ \text{Mobile source emission estimation} \\ & (5)\ \text{Destination Choice} \\ \hline \end{array} \]
A vehicle count survey (in Passenger Car Unit) is conducted on a mid-block section of a road at regular intervals of 15 minutes from 8:00 AM to 10:00 AM. Based on the data given in Table below, the Peak Hour Factor (rounded off to two decimal places) for the given survey duration is \(\underline{\hspace{2cm}}\).
In the transportation network given below, P, Q, R, S, T, and U are the nodes and values mentioned on the links denote time in minutes. Which of the following options represent the minimum spanning tree?
Match the models in Group I with their corresponding applications in Group II.\[\begin{array}{|c|c|c|} \hline \textbf{Group I} & & \textbf{Group II} \\ \hline \text{(P)} & \text{Logit model} & \text{(1) Trip assignment} \\ \hline \text{(Q)} & \text{Greenshield model} & \text{(2) Modal split} \\ \hline \text{(R)} & \text{Gravity model} & \text{(3) Traffic flow} \\ \hline \text{(S)} & \text{Multiple regression model} & \text{(4) Trip generation} \\ \hline & & \text{(5) Trip distribution} \\ \hline \end{array}\]
