Transportation Demand Management (TDM) planning should begin with evidence, not a standard list of bike racks, transit passes, rideshare spaces, or carpool programs. Before a development team commits to site changes or parking assumptions, transportation demand management planning services should determine how people are likely to travel, when demand will peak, and which alternatives to driving are practical at the site.
For developers, owners, architects, and municipal reviewers, the goal is a review-ready plan that connects trip activity, parking demand, access, curb use, and mobility options. MAPS can evaluate these conditions together, helping project teams identify transportation issues while design changes are still feasible.
Measure Trip Generation and Peak-Period Demand
A residential building, medical office, campus facility, mixed-use project, and commercial development will produce different travel patterns. Daily trip totals alone may not reveal the conditions that affect driveways, intersections, parking entrances, or pedestrian routes.
Effective transportation demand management planning services should evaluate projected trip generation, arrival and departure periods, travel purposes, and user groups. The analysis may include residents, employees, customers, patients, students, visitors, delivery drivers, service providers, rideshare users, pedestrians, cyclists, transit riders, and people with accessibility needs. Understanding these groups helps determine which TDM measures can influence travel behavior and when those measures will matter most.
Compare Parking Supply With Actual Demand
Parking planning should be evaluated alongside TDM because parking conditions often influence whether people choose to drive. A project may appear to require additional parking when the underlying issue is poor space allocation, concentrated shift changes, limited wayfinding, or demand occurring at different times among user groups.
A complete review should measure parking supply, projected demand, peak accumulation, duration of stay, shared-use opportunities, and the needs of residents, employees, visitors, and customers. This analysis can help prevent both excessive parking construction and operational shortages. MAPS provides parking demand analysis, shared parking studies, right-size parking, curb lane management, mobility data collection, and TDM planning as part of its transportation consulting services.
Evaluate Transit, Walking, Biking, and Accessibility
A nearby transit stop does not automatically make transit a practical option. TDM planning should examine service frequency, route destinations, stop access, sidewalk conditions, crossing safety, bicycle connections, lighting, and first- and last-mile barriers.
Accessibility should be assessed at the same time. The plan should review accessible parking, curb ramps, passenger loading, drop-off areas, pedestrian routes, and the distance between arrival points and building entrances. These details are particularly important for healthcare, residential, educational, public, and mixed-use developments.
Analyze Curb Activity and Site Access
Pick-up, drop-off, deliveries, loading, rideshare activity, shuttles, and service vehicles can create short periods of intense demand. Without early analysis, these activities may block driveways, interfere with parking entrances, conflict with pedestrians, or affect nearby traffic.
A review-ready plan should identify where curb activity will occur, when it will peak, how long vehicles will remain, and who will manage the space. It should also confirm that vehicles can enter, wait, load, unload, and leave without creating avoidable circulation or safety problems.
Define Measures, Responsibilities, and Performance Targets
TDM strategies should be selected after site conditions are measured. Depending on the findings, appropriate measures may include transit information, shuttle service, carpool support, bicycle facilities, pedestrian improvements, staggered schedules, shared parking, parking management, curb controls, wayfinding, or employee and resident communications.
The plan should also identify who will implement each measure, when implementation will occur, how performance will be monitored, and what adjustments will be made if results differ from projections. Forecasts are assumptions, so monitoring helps ensure that the plan remains useful after occupancy.
Conclusion
Before approval, TDM planning should measure travel behavior, peak demand, parking conditions, curb activity, transit access, walking and biking connections, accessibility, and implementation responsibilities. With MAPS’ integrated traffic, parking, and mobility perspective, transportation demand management planning services can help development teams make practical, financially responsible, and review-conscious decisions before costly commitments are made.
FAQs
1. When should TDM planning begin?
TDM planning should begin before the site plan is finalized, while access, parking, curb areas, pedestrian connections, and internal circulation can still be adjusted.
2. What data should be collected first?
The project team should review trip generation, peak-period activity, parking supply and demand, transit service, pedestrian and bicycle conditions, accessibility needs, curb activity, and expected user groups before selecting strategies.
