Overview
Introduction
Getting Started
Problem 1
The state and the city must decide whether a
traffic signal will improve the operation of the intersection of U.S.
95/Styner-Lauder Avenue. This problem focuses on the operations of the
intersection without consideration of the adjacent intersections.
Broader context of
Problem 1 with consideration for adjacent intersections for U.S. 95/Styner-Lauder
Avenue signalized and unsignalized scenarios. This problem addresses
operations of the U.S. 95 arterial, touching on timing and coordination
issues.
The University of Idaho attracts large
crowds during special events. This problem addresses the other than
typical peak period analyses to address these issues. A microscopic
simulation model is used to address intersection operations when demand
exceeds capacity.
Up to this point we have simplified the
analysis by assuming the signals were operating on fixed time. This
problem will examine the intersections with their existing
traffic-actuated signal control. In this problem we will touch on
estimating phase lengths, the effects of unit extension, and signal
coordination with actuated control.
Problem 5 addresses the operations of a
10-mile segment of U.S. 95 that travels through a hamlet. The first part
of the problem will address the segment with Chapter 20 of the Highway
Capacity Manual. The second part of the problem will address the 10-mile
segment of U.S. 95 with direct recognition of the hamlet, using stop
controlled intersection analyses to predict the cumulative delay. The
final section of the problem will analyze the potential for a bypass
that would avoid the hamlet.
Problem 6 provides a 20-year planning level
analysis of the various U.S. 95 intersections on the 10-mile segment.
The planning analysis will be used in this problem to identify future
lane configurations and control scenarios. This approach will identify
potential future concerns without dealing with the complexity and
uncertainty of the details associated with an operational analysis.
