Transportation Demand Management (TDM) Coordination


The City of New Haven secured a planning grant to revitalize central New Haven through transit-oriented economic development, and to reduce automobile trips in the Downtown Crossing district. Putting this grant to immediate effect, the City chose to engage major New Haven employers in advancing Transportation Demand Management (TDM) programs that would reduce their parking needs and help attract/retain employees. 


A comprehensive TDM strategy for the City was developed - including tactical strategies that are implementable at the employer/ consortium level. 

One recommendation of the project – to start a New Haven Transportation Management Association – was bid out as a separate project.

The TDM Coordination Project 

was completed in 2016.

The Southeast CT Council of Governments (SCCOG), is developing a comprehensive inventory and plan of the region’s bicycle and pedestrian programs and infrastructure. The Regional Bicycle and Pedestrian Plan will complement state and local planning efforts, and serve as a companion to the Region’s Long Range Transportation Plan. It will ensure that all of the municipalities in the SCCOG region have a basic level of bicycle and pedestrian planning, and that each town’s contribution to the network is documented - and considered in future planning efforts.


Holly Parker was involved in evaluating the project's existing conditions - as well as in the public outreach and engagement process. She created the project's public participation survey, and developed a Community Toolkit for implementing bicycle and pedestrian improvements. 

She also contributed to final recommendations. 

This project was completed in November of 2019.

Transit Pass & Parking Cash-Out Study

Transit Pass & Parking Cash-Out Study


As recommended in the 2015 Transportation Demand Management (TDM) Action Plan, the City of Burlington, Vermont sought to pilot a Transit Pass and Parking Cash-Out program 

for City employees. 

These two programs were designed to create availability in the parking system for downtown shoppers and businesses, and reduce traffic and air pollution, while improving the overall commute experience. 

Working with an advisory group within the City of Burlington, the economic costs and technical issues associated with the program and its implementation were analyzed.

The intent was to pilot these programs with City staff - & ultimately, to have them adopted by the downtown business community. 

This project was completed in 2016.
