Jacob manages data collection, reporting, and evaluation for ITDP globally. He specializes in strategic research that drives the conversation about sustainable transportation and development, assessing new technologies and identifying new, quantifiable ways of meeting program goals.

Jacob has been the lead researcher for many of ITDP’s most recognized publications, including the Bike Share Planning Guide, the BRT Standard, and A Global High Shift Cycling Scenario and Three Revolutions in Urban Transport, quantifying the multi-trillion-dollar savings in transportation costs and massive reductions in CO2 emissions possible through more sustainable urban transport. He also oversaw the production of ITDP’s People Near Transit report, which developed and measured an international metric for rapid transit coverage, which has since been adopted by city, national, and international governments.

Jacob has been responsible for data collection analysis—and, often, metric development—for ITDP projects worldwide, including a walkability study in five African cities and a BRT project in Nairobi, Kenya. Within the World Bank’s Sustainable Mobility for All program, Jacob co-chairs the Urban Access working group, which is developing sustainable urban transport indicators that are shared across multiple international institutions.

Jacob has a master’s in urban planning from McGill University (Montreal) and a bachelor’s in civil engineering from Columbia University.

Joe Chestnut works on implementing indicators to analyze organizational impact, urban growth, and walkability. Prior to his work at ITDP Joe was a research intern at The Brookings Institution in their Metropolitan Policy Program. He has a bachelor’s degree in International Affairs and Geography from The George Washington University and a master’s degree in Geography, also from The George Washington University.
