Philadelphia’s street design and daily commuting patterns create recurring risk scenarios:
- High-volume intersections with heavy turning traffic near office districts and transit hubs.
- Bus and rail-adjacent crossings, where foot traffic surges when trains arrive.
- Construction zones and lane shifts that reduce sightlines and change traffic flow.
- Nighttime visibility on streets with uneven lighting and reflective signage issues.
- Weather-driven hazards (rain, sleet, and seasonal snow) that affect stopping distance.
These factors matter because they influence what a “reasonable driver” should have done and what evidence will best show what happened.
