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.

Problem 2

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.

Problem 3

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.

Problem 4

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

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

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.
