Modernizing Transportation Management

Project Description 

With a growing number of residents, jobs, and visitors, the City of Los Angeles needs an updated set of transportation solutions to ensure that everyone has efficient, sustainable, and safe access to their destinations. Transportation demand management (TDM) can help achieve these goals in innovative ways.

TDM includes a broad spectrum of strategies that enhance people’s mobility, from information, support, and incentive programs to investments in connected, complete streets. The City’s TDM Program helps manage the use of infrastructure by ensuring new developments are designed to promote and support a full range of mobility options. The TDM Program can shift Angelenos and visitors’ travel choices, taking advantage of regional transit system investments and encouraging active transportation. TDM will foster active and healthy lifestyles, improve quality of life, and reduce harmful emissions.


An update to the City’s TDM ordinance is long overdue. The current 25-year-old TDM ordinance no longer meets the needs of a modern, growing city. It does not account for on-demand and shared mobility services that have changed people’s travel behavior in recent years. New mobility services, such as bike share, carshare, on-demand rides, and other smart technologies offer more options than we ever could have imagined in 1993.

How Was the Ordinance Developed?
To update the TDM ordinance, City staff began by conducting a review of best practices across the country. Staff then coordinated with local, regional, and state agencies to align our goals and strategies. Throughout the process, staff engaged with community groups, residents, business associations, and other stakeholders to ensure the ordinance could meet Los Angeles’s unique context. 


The TDM Program aims to improve people’s access to destinations as the population grows. Shifting travel from driving alone (single-occupancy-vehicle (SOV) trips) to sustainable travel choices will minimize the impacts of new developments on the transportation system.


  • Better environmental and public health outcomes: Shifting travel away from SOV trips will improve air quality, promote public health, reduce vehicle miles travelled (VMT), and cut public and personal costs.
  • Improved quality of life: Improving the quality of travel experience and the well-being of travelers will make the transportation system more useful, usable, desirable, findable, accessible, and credible.
  • Context-sensitive solutions: The TDM Program is designed to meet the needs of diverse communities by offering a wide menu of choices for each development. These options account for land-use and transportation variations citywide. A flexible program will best serve people and neighborhoods with mobility solutions.  
  • Adaptive by design: City staff can periodically update the TDM strategies to ensure the program is responsive to new mobility technologies and innovations and to evolving travel preferences and needs. Applicants may also suggest new measures for consideration.
  • Streamlined project review, monitoring, and evaluation: The TDM Program provides project applicants with a clear and predictable process to obtain project approval as well as yearly opportunities to alter their plan should monitoring and evaluation demonstrate a need for adjustment. Regular project performance monitoring and evaluation ensures a transparent process efficient for both the applicant and the City.
  • Program performance evaluation: The Program will generate data testing the TDM measures’ long-term effectiveness in achieving program goals and providing the greatest public benefit. The City can utilize this data to inform future transportation and land-use planning.
