Transportation Demand Management
Transportation Demand Management (TDM) is the application of strategies, policies, and programs to better manage transportation needs. It is a cost-effective approach to improving transportation by maximizing mobility choices that meet and exceed traveler needs.
TDM Implementation – HNL Connect
The Honolulu Connect (“HNL Connect”) project began in September 2024 as the vehicle for the formal implementation of the City’s Honolulu Transportation Demand Management (TDM) Plan. A major part of this implementation is a TDM software platform now under development that is intended to provide Honolulu residents and visitors, and City employees with information and encouragement to connect to their destinations through alternative sustainable travel options. The primary HNL Connect strategies also include:
- Travel Challenges
- Targeted marketing and overall TDM communications and monitoring
- Vanpool subsidies
- Restricted Parking Zone management
- Developer TDM incentives compliance monitoring
- City employee TDM and parking
By carrying out these primary strategies, as well as supporting strategies including TDM-oriented public parking pricing management, education for public officials and business owners, multimodal efforts including potential area micro-transit and mirco-mobility options, and carpool matching through HiRideShare. HNL Connect is helping to achieve the City’s Transportation, environmental, economic, health and equity goals as detailed in the TDM Plan.
Honolulu TDM Plan
The City and County of Honolulu in cooperation with the Oʻahu Metropolitan Planning Organization and the United States Department of Transportation developed a TDM Plan to reduce vehicle miles traveled and increase walking, bicycling, rideshare and transit use. It will help achieve the City’s transportation, environmental, economic, health and equity goals. The program is intended to help transform the way we use transportation resources to improve mobility and quality of life while reducing greenhouse gas (GHG) emissions and transportation costs.
The TDM Plan developed targets and strategies that are informed by community and stakeholder engagement, including:
- Online TDM monitoring and reporting system
- Marketing support and education materials
- Legislative changes and enabling policies
- TDM programs to support more active transportation
- Evaluation and monitoring to measure success of the TDM Plan
The development of the TDM Plan was consistent with the City’s 2018 Climate Change directive and the regional goals outlined in Oʻahu Regional Transportation Plan (ORTP), Complete Streets Ordinance 12-15, Honolulu Complete Streets Design Manual, Oʻahu Bike Plan Update, Oʻahu Pedestrian Plan, and Complete Streets Transportation Impact Assessment Guidelines and Instructions.
