Documenting the Effectiveness of Travel Demand Management Measures

Case Study on TDM Plans in Reducing Traffic Generation and Peak Parking Demand

A number of  years ago we conducted a study documenting the effectiveness of travel demand management (TDM) plans in reducing peak hour traffic generation and peak parking demand in six office complexes in Minnesota.

ITE Trip Generation Results in Phantom Trips?

At least that’s the thesis of Adam Millard-Ball in an article posted on Access titled Phantom Trips.  I agree with him that if one was going to use the trip generation rates in ITE’s Trip Generation Manual as the foundation for regional traffic forecasts, you would be significantly over-estimating the traffic in the region.  You could use ITE […]
