Mannering Traffic Analysis and Highway engineering chapter 7 Traffic Control Problem 7.20 Q : I need a queueing diagram for this problem, so that i can successfully understand the mechanics of these types of problems. Im having trouble understanding how to “set-up” the problems and creating equations of lines that sucessfully show accurate queueing relationships Problem statement: The saturation flow rate for a pretimed signalized interesection approach is 1800 veh/hr. The cycle length is 80sec. It is known that the arrival rate during the effective green is twice (2x) the arrival rate during the effective red. During one cycle, there are two (2) vehicles in the queue at the beginning of the cycle and there are eight (8) vehicles in the queue at the end of the effective red. If the queue clears exactly at the end of the effective green D/D/1 queuing applies, determine the total vehicle delay in the cycle (in veh-sec) . Ps : please provide queueing diagram . Greatly appreciated !

Hello, I am looking for someone to write an article on Britain Fights EU’s ‘Big Brother’ Bid. It needs to be at least 500 words. Britain Fights EU’s ‘Big Brother’ Bid

Analysis

The article “Britain fights EU’s ‘Big Brother’ bid to fit every car with speed limiter” (Owen, 31 August 2013) was written by Glen Owen and published in the Daily Mail on 31 August 2013. The main points in the article is the proposition by European Union through the European Commission to fit each car with a speed limiter that has a camera that read roads signs and a satellite that communicates speed limits to the driver (Owen, 31 August 2013). An alarm then goes off when the limit is breached for the advice option, the driver uses an arrest to slow down and has an option of disabling the device or the third option is mandatory, where in no way can the driver be allowed to exceed the speed limit. The aim of the Intelligent Speed Adaptation technology (ISA) is reducing accident death tolls by a third but according to Mr McLoughlin, UK Transport Secretary, comparing UK road deaths of 1754 deaths to 3,645, and 3,657 deaths in France and Germany respectively, UK has lowest death rates from road carnage in Europe. After being briefed that newly, designed vehicles will have camera and satellite systems allowing for easy and cheap addition of speed limiters, Mr McLoughlin instructed his officials to block the move terming it as a violation of British motorist’s freedom. According to AA the new technology is poised to create dangers at lower speeds especially when there is a requirement to accelerate and the speed is limited resulting in an avoidable collision but believes audible speed alerts would work (Owen, 31 August 2013).

EC reports that ISA and other issues will be published by the commission in a document in the autumn according to its mandate by member states and that there are ongoing consultation on the speed limiters.

Evaluation

The research in the article is exemplary done owing to the reporting of the views of the different stakeholders on the introduction of ISA and this has a relation to the course material since it deals with a transportation policy issue aimed at implementation in the UK and Europe limiting driving beyond set speeds. The exemplary sections in the article are the workings of the Intelligent Speed Adaptation technology (ISA) that is well explained in the article allowing for a clear concise understanding by the reader. The appropriate data presented in the article include the death toll rates from accidents in the European Union to which the Intelligent Speed Adaptation technology (ISA) is poised to reduce by a third and those in United Kingdom, France, and Germany that are given for comparison purposes.

The article clearly reports that the result was a clear rejection by the UK transport minister of the planned implementation of Intelligent Speed Adaptation technology (ISA) in UK and clearly gives his reasons for the rejection. This is a good study due to the consideration of the statistics on road safety in different member states, different stakeholder views, and the conclusion is based on this information. The subject of the article is applicable to a transport organization that uses road transport as it affects the ability of cars to travel at speeds beyond the stated limits if the policy is implemented in the United Kingdom. This would result in high transportation costs, long travel times, and a reduction in revenue for the transportation organization.
