Assessment Task 2: Transport Modelling and Operations
This is an individual assignment
Please answer the following questions and present your work in a report format clearly including your name and student ID on the cover page.
Problem 1: Speed, Flow and Density Modelling using Tube Count Data (50 marks)
A traffic survey has been conducted on Gardners Road (highlighted in red), between the intersection of Botany Road and O’Riordan Street, as shown in Figure 1. The survey used automatic tube vehicle counts (pneumatic tubes) which collected speed and volume data between 6/03/2016 and 12/03/2016 (7 day survey period). The data is presented in the associated spreadsheet (“48370 Assessment Task 2 – Traffic Survey Data”).
Analyse the provided data and answer the following questions;
For the remainder of the question, remove the observations where zero flow occurs and assess conditions for BOTH eastbound and westbound directions of travel.

If the arrival of the vehicles on the major road can be described by the Poisson distribution, and the peak hour volume is 1100 veh/hr, determine the expected number of accepted gaps that will be available for minor road vehicles during the peak hour. (5 marks)
Problem 3: Case Study – Swiftsville Local Area Traffic Management planning (30 marks)
Swiftsville is a local government area in the little known country of Congestingvania. Congestingvania, is a country that prides itself on road safety and has the goal of developing truly integrated, sustainable and efficient transport systems. The residents of Swiftsville have alerted the authorities of a series of safety concerns within the local road network. The study area for the roads in question is presented in the map below.
As the Traffic Engineer for the local government of Swiftsville, you are required to provide advice and design solutions for the community regarding the following concerns (listed as a), b) and c) in the proceeding pages of the brief).
For each concern;
Residents have complained about vehicles speeding and the number of crashes observed on Cheetah Road between Marlin Avenue and Taipan Street. Furthermore it is difficult for pedestrians to cross the road near Hare Street and Marlin Street. Below are photographs of the study area:

Marlin Avenue is a local street which provides access to residences, Snail Avenue and most importantly the Swiftsville Recreation Grounds. Given this context, the community has requested further facilities and a reduction in vehicle speeding to encourage cycling and pedestrian activity along Marlin Avenue.

Prior speed studies have indicated that Turtle Way (between Wolf Road and Cheetah Road) has 85th percentile speeds that are 10km/hr greater than the sign-posted speed limit of 50km/hr. As a mitigation strategy, speed cushions were implemented however residents are still concerned about speeding and pedestrian accessibility along Turtle Way and are demanding remediation.
