3 49102 Traffic and Tratl!;portation - Main Exam QUESTION 1 (101\farks) a) Govemments are recognising the importance of effective networks in a more sustainable manner. This requires consideration not only of the required. oi desirable traffic flow conditions on '"...,.. differ~nfparts of the road network, but also broader issuesth.at must be addressed. Listal1d discuss four (4) of the broader issuesithatirmst be considered when planning for the management of land-use and road network. In your own words what is your understanding of the term Traffic Management? One of the overall aims of Traffic Management is to facilitate the operation of traffic on roads with safety and efficiency, taking into account the needs of a range of road users. Who are these road users?< Discuss how each of their needs can be met from traffic and/or transport management perspectives. QUESTION2 (8Marks) ::- < a) There ar~ two (2) terms given to the collection of traffip data to assist the Traffic Engineer to assess the Operational efficiency of a designated road nytwdrk.... ~. Na11l.e and give a brief description of the two tenp.s. b) Traffic studies have a central place in trarispott.planning and traffic engineering. List three reasons why traffic studies arepefformed. c) Once data is gathered through traffic studies it can serve a number of purposes. List and describe three (3)p1Jrposes for which traffic data can be employed, Autumn 2015 Page 3 of7

4 49102 Traffic and Transportation - Main Exam QUESTION3 (12 Marks) a) Define the terms volume, density and speed. Discuss the basic relationship between the three. b) The term "Level of Service" (LOS) is a qualitative measure describing operational conditions within a traffic stream. List and describe each of these levels of service. c) In the analysis of capacity, level of service and degree of saturation there are a number of factors that impact on the actual capacity of the roadway. List and discuss the effect of any four (4) of these factors. QUESTION 4 (8 Marks) a) Define and distinguish between the terms uninterrupted traffic flow and interrupted traffic flow. b) When analysing the capacity of roads under uninterrupted flow conditions four (4) road types are generally examined, namely: 1. single lane flow n. two-lane, two-way roads 111. multi-lane roads (divided and undivided) IV. freeways Define each of the above four ( 4) road types and indicate features of each that are most likely to influence the capacity (performance) of that road type. QUESTIONS (8 Marks) a) Describe fully in your own words your understanding of the term 'Road Network Management'. b) There are two basic approaches to managmg transport, supply management and demand management Give a brief description of each and include strategies on how each one can be achieved. c) The primary function or balance of different road functions may be reflected in the classification of a road. In its purest form, road classification consists of two basic road types which have fundamentally different traffic and environmental goals. List and describe the functions of the two road types.

5 49102 Traffic and Tran~portation- Main Exam QUESTION6 (12J\1arks) a) Explain the following terms in relation to intersections, their design and operation (provide sketches where appropriate). 1. at,grade intersection u. chanrielization iii. intersection sight distance iv. auxiliary lanes v. roundabout v1. signal phase signal cycle length b) What is traffic signal co-ordination? List five ( 5) benefits arising from traffic signal coordination. QUESTION7 (8 Marks) a) '"" '''...:::_::._ :.: Traffic congestion. in urban areas is one of the greatest challenges facing traffic engineers and transport planners. In your view what measures are available to best manage.this congestion today and into the future? b) In terms of urban planning, define the Jenp:inology "Activity Centre" and what are.. tht;t... /distinguishing feature and purposes of such Cet:Ltres.

6 49102 Traffic and Transportation -Main Exam QUESTIONS (10 Marks) a) Local Area Traffic Management (LATM) is concerned with the planning and management of the usage of road space within a local area. Explain the terminology LATM and how it is different from other aspects of traffic management. b) The primary target of LA TM is to change driver behaviour, both directly by physical influence on vehicle operation, and indirectly by influencing the driver's perception of what is appropriate behaviour in that street. One of the primary objectives of LATM is to minimise the risk of a crash occurring. List four (4) treatments that could be employed within an LATM scheme that would reduce the risk of a crash occurring. c) In LATM planning, many devices introduce additional complexities for cyclist/pedestrian/driver interaction and therefore separation in the vicinity of treatments may be desirable. What do you consider are the general principles that should be followed when determining the placement and nature of LA TM devices? QUESTION9 (12 Marks) a) IV. V. From a road user support perspective, the main fields of road network operations are: Network monitoring Maintaining road serviceability and safety Traffic control Travel aid and user information Demand management Explain in detail each of these five operations and give an example of each. b) What is your understanding of Traffic Control Devices (TCDs )? Describe their main functions. Detail the operation of three (3) TCDs. c) Why is the provision of Parking so important for successful Traffic/Transport Management? List the main requirements to achieve the effective provision for parking. Page 6 of 7 Autumn 2015

7 49102 Traffic and Tran~portation - Main Exam QUESTION 10 (12 Marks) a) Different groups of road users have different design and safety.needs when considering the traffic impact ofa major development. List these main users and indicate how you would provide for each oftheir needs. b) A Safe Road Environment (SRE) should provide certain features so that road users are safely and wellinformed. Detail six (6) of these features anghowdo they assist the road user. How would you apply each of the 6 SRE principles detailed in [b] above to ensure a safe intersection design? Autumn 2015 Page 7 of7
