Question

What data is needed from each traffic analysis zone to forecast future volumes?

1. population, no. of vehicles, miles of roadway, and no. of buses
2. no. of licensed drivers, no. of vehicles, and no. of households
3. zone boundaries, traffic nodes and centroids, employment
4. forecasted population, no. of jobs, and no. of households

Maximum Service Flow Rate is determined under…

1. ideal weather and pavement conditions
2. ideal driver and vehicle conditions
3. ideal roadway and control conditions
4. ideal vehicle user conditions (no trucks)

Answer 1

Ans 1 : d) Forecasted Population , Number Of Jobs , And Number Of Households , this is data that is needed for each traffic analysis zone which would forecast future volumes because , there are two types of data which is required for traffic forecasting data is know data and the predicted data . These are the predicted data (future data) which are combined with the current known data so as to calculate the estimate , which would require all these value i.e forecasted population, no. of jobs, and no. of households to get an accurate result without errors so as to avoid future modifications

Ans 2 : c) ideal roadway and control conditions , Maximum service flow rate and capacity is the relatable to each other and capacity is inversely proportional to the minimum headway and which depends upon the type of control system . The equation for Capacity and minimum average headway is mentioned below :

where , C = Capacity

Hmm = Minimum average headway
