PHILOSOPHY AND LEARNING OBJECTIVES:
This 15 point elective paper is focused towards traffic engineering (operations), design of intersections and traffic / transportation planning. The topics covered complement those covered in Part III, Transportation Engineering 1 and 2 (CIVIL 360 and CIVIL 361) and also in the Part IV Second Semester paper, CIVIL 759: Highway and Transportation Design (previously CIVIL 461). The objective is to provide a basis for those wishing to include traffic engineering and traffic / transportation planning within their field of expertise.
Although the accent of the course will be on analytical techniques used in planning and design applications at the project level, some emphasis will be given to systems planning techniques at the network level. Some hours will be used for problem solving, the projects and revision / maybe the test. Some exercises may be set but not used for assessment. Examples of professional practice will be shown at relevant stages.
LABORATORIES:
This will comprise using SIDRA INTERSECTION, a computer software package for a project analysing the performance of two signalised intersections, a priority intersection and a roundabout.
ASSESSMENT:
Design Projects (70%) including,
· Intersection Design and Analysis Project 45%
· Public Transport Design and Transportation Planning Project 25%
Final Examination (30%)
Note: Student must achieve 50% or greater in the final examination to pass this course.
COURSE OUTLINE:
Traffic Modelling - PR
Introduction to transport models and a range of modelling packages, types of models and packages available in NZ and overseas, selection framework and criteria, traffic stream models, traffic flow modelling based on shock wave theory and queuing theory, capacity analysis of roundabouts.
Signal Timing and Capacity - PR
Signal design using ARR 123 lane by lane analysis techniques for multi-phase controllers (movement times, critical movements, degrees of saturation, saturation flow factors, gap acceptance for turning traffic, unequal lane utilisation, blocked lanes).
Intersection Operational Performance – PR
Under-utilisation of lanes (blocked and short lanes), measures of performance (delays, stops queue lengths), use of the SIDRA computer package for signals / roundabouts / priority intersections, measurement of delay and saturation flows at a signalised intersection, basis of coordination and area control.
Transportation Planning - SC
Conventional four-stage modelling – trip generation, trip distribution, modal split and traffic assignment with application in a project, traffic impact assessment and the transportation planning processes, related legislative framework requirements (Resource Management Act, Land Transport Management Act)
Public Transport (PT) – SC
Design of PT network of routes, reliability of PT service, Integrated systems (e.g. AT’s RPTP) and travel behaviour, vehicle scheduling, crew scheduling
