TRB’s National Cooperative Highway Research Program (NCHRP) Report 716: Travel Demand Forecasting: Parameters and Techniques provides guidelines on travel demand forecasting procedures and their application for helping to solve common transportation problems.

In addition, models for optimal transportation supply decisions are integrated with the demand models. Transit travel and goods movements are specifically addressed.

The authors combine measures of urban form and public transit supply for 114 urbanized areas with the 1990 Nationwide Personal Transportation Survey to address two questions: (1) How do measures of urban form, including city shape, road density, the spatial distribution of population, and jobs-housing balance affect the annual miles driven and commute mode choices of U.S. households? (2) How does the supply of public transportation (annual route miles supplied and availability of transit stops) affect miles driven and commute mode choice? The authors find that jobs-housing balance, population centrality, and rail miles supplied significantly reduce the probability of driving to work in cities with some rail transit. Population centrality and jobs-housing balance have a significant impact on annual household vehicle miles traveled (VMT), as do city shape, road density, and (in rail cities) annual rail route miles supplied. The elasticity of VMT with respect to each variable is small, on the order of 0.10-0.20 in absolute value. However, changing several measures of form simultaneously can reduce annual VMT significantly. Moving the sample households from a city with the characteristics of Atlanta to a city with the characteristics of Boston reduces annual VMT by 25 percent.

What are the best transit cities in the US? The best Bus Rapid Transit lines? The most useless rail transit lines? The missed opportunities? In the US, the 25 largest metropolitan areas and many smaller cities have fixed guideway transit—rail or bus rapid transit. Nearly all of them are talking about expanding. Yet discussions about transit are still remarkably unsophisticated. To build good transit, the discussion needs to focus on what matters—quality of service (not the technology that delivers it), all kinds of transit riders, the role of buildings, streets and sidewalks, and, above all, getting transit in the right places. Christof Spieler has spent over a decade advocating for transit as a writer, community leader, urban planner, transit board member, and enthusiast. He strongly believes that just about anyone—regardless of training or experience—can identify what makes good transit with the right information. In the fun and accessible Trains, Buses, People: An Opinionated Atlas of US Transit, Spieler shows how cities can build successful transit. He profiles the 47 metropolitan areas in the US that have rail transit or BRT, using data, photos, and maps for easy comparison. The best and worst systems are ranked and Spieler offers analysis of how geography, politics, and history complicate transit planning. He shows how the unique circumstances of every city have resulted in very different transit systems. Using appealing visuals, Trains, Buses, People is intended for non-experts—it will help any citizen, professional, or policymaker with a vested interest evaluate a transit proposal and understand what makes transit effective. While the book is built on data, it has a strong point of view. Spieler takes an honest look at what makes good and bad transit and is not afraid to look at what went wrong. He explains broad concepts, but recognizes all of the technical, geographical, and political difficulties of building transit in the real world. In the end,Trains, Buses, People shows that it is possible with the right tools to build good transit.
