8.4 Consider a Poisson regression model for the number of social/recreational trips generated during a peak-hour period that is estimated by (see Eq. 8.3 2 ) BZ; = -0.75+0.025(household size) + 0.008(annual household income, in %3D thousands of dollars) + 0.10(number of nonworking household members). Suppose a household has five members (three of whom work) and an annual income of $100,000. What is the expected number of peak-hour social/recreational trips, and what is the probability that the household will not make a peak-hour social/recreational trip?

Poisson Model is used for the segment of a certain highway. Vehicles are recorded at 30-seconds intervals, the result is established that in 2251 of 20000, there are 4 vehicles arrived. Determine the number of these 20000 intervals in which, 6 automobiles arrive at the same time.
A large residential area has 1500 households with an average household income of $15,000, an average household size of 5.2, and, on the average, 1.2 working members. Using the model below, predict the change in the number of peak-hour social/recreational trips if employment in the area increased by 20% and household income by 10%. number of peak-hour vehicle-based social/recreational trips per household = 0.04 + 0.018(household size) + 0.009(annual household income [in thousands of dollars]) + 0.16(number of nonworking household members) Round off final answers to whole number.

A work-mode-choice model is developed from data acquired in the field in order to determine the probabilities of individual travelers selecting various modes. The mode choices include automobile drive alone (DL), automobile shared-ride(SR), and bus (B). The utility functions are estimated as: UDL = 2.6 – 0.3(costDL) – 0.02(travel time DL) USR = 0.7 – 0.3(costSR) – 0.04(travel time SR) UB = –0.3(costB) – 0.01(travel time B) where cost is in dollars and time is in minutes. The cost of driving an automobile is $5.50 with a travel time of 21 minutes, while the bus fare is $1.25 with a travel time of 27 minutes. How many people will use the shared-ride mode from a community of 4500 workers, assuming the shared-ride option always consists of three individuals sharing costs equally?

Kindly provide a complete solution in 3 decimal points.
I need an answer asap with complete solution. Ty 1.The trip rate (y) and the corresponding household sizes (x) from a sample are shown in table below. Compute the trip rate if the average household size is 3.25 (Hint: use regression method).
A small town has residential zones, A and B, producing 900 and 600 work trips respectively. Zone C, D, and E are work opportunity zones attracting 900, 400, and 200 trips. The travel times between the zones and the actual observed trips are as above. Develop a set of travel time factors (fij) for use in a gravity model that will produce a reasonable approximation of the observed trips. Start with an initial value of fij =1 for all links Please clearly show your calculations and provide any explanations/assumptions you may have
At a specified point on a bicycle path, bicycles are assumed to arrive according to a Poisson probability distribution. Bicycles are counted in 15-second intervals for a period of 30 minutes (a total of 120 intervals). It is noted that no bicycles arrived in 30 of those 120 intervals. a) What is the expected number of bicycles in any one-minute period? b) What is the average volume, in vehicles per hour? c) How many of these 120 intervals have exactly three bicycles arriving ? Please give me all answers... Help me urgent Thank you

The following 3 Travel Demand Forecasting models were created to estimate the number of peak-hour trips in the suburb of Croydon: T1 = 1.0 + 0.3(household size) + 0.01(household income in thousands of $) T2 = 1.5 + 0.2(household size) + 0.01(household income in thousands of $) T3 = 0.5 + 0.5(household size) + 0.01(household income in thousands of $) The suburb has a total of 3500 households with an average of 4 people per household, an average household income of $90,000 and survey data shows that it generates a total of 11,550 trips in the peak-hour. Which of the above models is the most accurate? A. T1 B. T2 C. T3 D. Can't say as 2 or more models are equally accurate.
The arrival of vehicles at a specified roadway location is Poisson distributed. The flow count shows 540 veh/hr at this roadway location. - What is the probability that headway between successive vehicles will be less than 6 seconds? - What is the probability that headway between successive vehicles will be greater than than 12 seconds? - What is the probability that headway between successive vehicles will be between 6 and 12 seconds? - Draw the probability density function of the exponential distribution and show the key items in the graph. - Draw the cumulative distribution of the exponential distribution and show the key items in the graph.
