Developing SafeSpot: A New Crowdsourcing Tool for Real-Time Near-Miss Detection and Risk Mapping
Tanmoy Bhowmik
Primal Pappachan
Transportation safety analysis has traditionally relied on police-reported crashes to identify dangerous locations. This reactive approach overlooks the many near-miss incidents and perceived hazards that occur daily but go unrecorded. Understanding such incidents is essential for proactive transportation safety planning, allowing for interventions before injuries or fatalities occur. However, current practice lacks a systematic way to collect and analyze near-miss data, creating a critical g...

Development of a Pedestrian Demand Estimation Tool
Kelly Clifton
There is growing support to improve the quality of the walking environment and make investments to promote pedestrian travel. Such efforts often require analytical non-motorized planning tools to estimate levels of pedestrian demand that are sensitive to environmental and demographic factors at an appropriate scale. Despite this interest and need, current forecasting tools, particularly regional travel demand models, often fall short. Until recently, spatially disaggregate travel behavior dat...
