Applying dynamic traffic assignment in modeling permit-restricted parking utilizing microscopic traffic simulation

Abstract

Many universities are evaluating ways to improve mobility while dealing with increased demand for parking within the campus. Different types of parking strategies are considered as potential tools for improving campus mobility and meeting increased parking demand. Limited information is available on how removing on-street parking from the center of a university campus, relocating motorists to park on the periphery of campus, will impact the neighboring transportation system. Although dynamic traffic assignment (DTA) is a valuable tool for evaluating such impacts, most previous studies have used DTA with mesoscopic models. Thus, there is also limited guidance on the application of DTA within microscopic simulation models. The purpose of this study was to test a novel methodology for evaluating the mobility impact of relocating parking. The authors developed a method of utilizing DTA within a microscopic traffic simulation model. This model was applied to a case study capturing the changes in traffic patterns and volumes as a result of university parking changes. The authors found the methodology efficient and repeatable, and identified several simulator challenges with this new application. The case study findings suggest that, due to the significant number of motorists searching for the high-demand parking in the core of campus, relocating this parking to periphery lots will reduce the average travel time, even when accounting for the increased walking time.

Best Option For Reducing On-Campus Private Car-Based CO2 Emissions: Reducing VKT Or Congestion?

“…Finally, O-D matrix and parking information were assigned to the PTV-VISSIM to evaluate the traffic performance. Fries et al (2011) also evaluated the mobility impact of relocating parking at Clemson University campus in South Carolina using PTV-VISSIM. The network consisted of 742 nodes and 20,000 links and traffic data were collected by manual counts and video footage.…”

Could the Incentive Policy of Shared Parking Be Sustainable? The Viewpoint of Personal Risk Aversion

“…As an important part of urban transport systems, static traffic, which is an extension of dynamic traffic, can have a positive or negative effect on dynamic traffic, urban mobility, and even human health [1,2]. With the development of motorization and decreases in available resources in cities, parking is becoming a major challenge for both commuters and transport managers [3].…”

How to evaluate the extent of mobility strategies in a university campus: An integrated analysis of impacts

“…However, the analysis discarded emission and safety impacts. The assessment of factors impacting travel mode on campus parking areas has been attracted attention, as evidenced by several published work (Bridgelall, 2014;Elliott, Jayachandran, Kumar, & Metzer, 2013;Fries, Chowdhury, & Dunning, 2012;Guo, Huang, & Sadek, 2013;Jung, Ha, & Park, 2017;Moradkhany, Yi, Shatnawi, & Xu, 2015;Proulx, Cavagnolo, & Torres-Montoya, 2014). Fries et al (2012) used a dynamic traffic assignment on a campus parking area, but the research was centered on vehicle delay.…”
