Interchanges are a particularly important focus in transportation because of the high level of interacting cross-traffic. Often, traditional diamond interchanges are limited in their ability to provide adequate safety and operational needs. Alternative interchanges are a common solution that involve using innovative designs which work well with specific site characteristics. Because there are often many alternative designs to consider and because it can be time-consuming to model and evaluate each alternative, there is a need to expedite the process using a designated screening approach and evaluation. This thesis contains an interchange study for a corridor located in Columbia, Missouri that uses a screening process which incorporates analytical and simulation tools. Several interchanges are analyzed including: diamond, single point urban (SPUI), partial cloverleaf, diverging diamond interchange (DDI), displaced left turn (DLT), roundabout, and an innovative displaced left roundabout (DLR). The results of operational analysis show that: the DDI performs the best on the interchange for high demand; the DLR performs best for the interchange only at low demand; the current design is sufficient with the given growth volume, so an alternative is not warranted. One contribution of this thesis is the development of a systematic procedure that first screens for promising designs and then conducts an extensive simulation analysis to compare their performance.

Get a complete look into modern traffic engineering solutions Traffic Engineering Handbook, Seventh Edition is a newly revised text that builds upon the reputation as the go-to source of essential traffic engineering solutions that this book has maintained for the past 70 years. The updated content reflects changes in key industry standards, and shines a spotlight on the needs of all users, the design of context-sensitive roadways, and the development of more sustainable transportation solutions. Additionally, this resource features a new organizational structure that promotes a more functionally-driven, multimodal approach to planning, designing, and implementing transportation solutions. A branch of civil engineering, traffic engineering concerns the safe and efficient movement of people and goods along roadways. Traffic flow, road geometry, sidewalks, crosswalks, cycle facilities, shared lane markings, traffic signs, traffic lights, and more—all of these elements must be considered when designing public and private sector transportation solutions. Explore the fundamental concepts of traffic engineering as they relate to operation, design, and management Access updated content that reflects changes in key industry-leading resources, such as the Highway Capacity Manual (HCM), Manual on Uniform Traffic Control Devices (MUTCD), AASSHTO Policy on Geometric Design, Highway Safety Manual (HSM), and Americans with Disabilities Act Understand the current state of the traffic engineering field Leverage revised information that homes in on the key topics most relevant to traffic engineering in today's world, such as context-sensitive roadways and sustainable transportation solutions Traffic Engineering Handbook, Seventh Edition is an essential text for public and private sector transportation practitioners, transportation decision makers, public officials, and even upper-level undergraduate and graduate students who are studying transportation engineering.
