DRAFT Comprehensive Transportation Plan Update: 2/23/2018 version

SCENARIO

PLANNING

INTRODUCTION

Places that can demonstrate the ability to deal with competing interests in ways that allow them to make informed, strategic choices can

prepare themselves for success. These choices typically occur through an analytical process that is balanced with vision and creativity. The

Town of Morrisville Comprehensive Transportation Plan Update included ways to:

Identify what the community values,



 Create and test alternative approaches to accommodating growth, and  Select—and modify—the alternative that is best aligned with community values. Scenario Planning Process The scenario planning process included the use of a digital growth model designed to test the performance of different corridor-based

growth patterns. The purpose of this test was to generate information to help to explore how different growth patterns would affect the

transportation network. The Morrisville scenario planning process ( Figure E-1 ) included an investigation into three scenarios: NC 54;

McCrimmon Parkway (including future extension); and Town Hall Drive. Two alternatives for each scenario were compared to a baseline

scenario that represented the continuation of Figure 5.1, Future Land Use, in the 2009 Land Use Plan . The performance of each corridor

scenario was tested against a series of performance indicators that represent the values that the Morrisville community identified as

priorities.

Connect 2045 Connect 2045 is an update to the Imagine 2040 Scenario Planning process. The scenario planning process represents a partnership between

the Capital Area Metropolitan Planning Organization (CAMPO) and the Durham-Chapel Hill-Carrboro Metropolitan Planning Organization

(DCHC MPO) to promote a coordinated decision-making process for a more sustainable transportation system. Connect 2045 uses

CommunityViz software to measure and evaluate the impacts of growth patterns and major investments in the regional transportation

system. The Triangle CommunityViz2 model was created in efforts to develop the growth forecast for the 2045 Metropolitan Transportation

Plan . This model was used to test each individual corridor scenario for the Town of Morrisville Comprehensive Transportation Plan

Update .

Testing Scenarios PLACE TYPES AND COMMUNITY TYPES The corridor-based alternative scenarios were developed by assigning place types throughout the study area to simulate future

development patterns. These place types are a direct input of the Triangle CommunityViz2 Model and include 30 different options. These

place types also fall into larger categories, called community types, which represent a simplified communication tool to better understand a

scenario’s general development pattern. The larger categories include: Rural; Suburban; City and Town; Industrial; and Special.

ALTERNATIVES Three scenarios were tested for each corridor (McCrimmon Parkway, NC 54, and Town Hall Drive) with two alternatives compared against a

scenario reflecting Figure 5.1, Future Land Use, in the 2009 Land Use Plan.
