Affordable Housing Trip Generation Strategies and Rates
Kelly Clifton
Kristina Currans , Susan Handy , Robert Schneider
Assessment and mitigation of transportation impacts based on travel demand is required by state, federal, and local laws in California. Determining trip generation is typically the first step in preparing these transportation impact analyses, and current industry standard practice relies on trip rates published by the Institute of Transportation Engineers (ITE). However, ITE protocols emphasize vehicle trip rates without sensitivity to urban context or socioeconomic characteristics, which can...

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...
