Final answer:
The dangerous elements of mixed-use roads include pedestrians crossing, bicycles sharing the road, vehicles traveling at high speeds, and lack of proper signage and markings.
Step-by-step explanation:
The dangerous elements of mixed-use roads are:
- Pedestrians crossing: Pedestrians crossing the road can be at risk of being hit by vehicles if there is no proper infrastructure or designated crosswalks.
- Bicycles sharing the road: Bicycles sharing the road with vehicles can increase the risk of accidents if both parties are not aware of each other's presence or if there is a lack of proper bike lanes or signage.
- Vehicles traveling at high speeds: Vehicles traveling at high speeds in mixed-use roads can pose a danger to pedestrians and bicyclists as they have less time to react to avoid collisions.
- Lack of proper signage and markings: When mixed-use roads lack proper signage and markings, it can lead to confusion and unsafe conditions for all users of the road.
