Cross-city crash severity analysis with cost-sensitive transfer learning algorithm

作者:

Highlights:

• Propose unified feature representation for cross-city crash records feature alignment.

• Develop two transfer learning based cross-city crash severity models.

• Adopt the cost-sensitive learning method to tackle the class imbalance issue.

• Identify more accurate significant crash contributing factors to crash severity level.

• Extract and explain common crash contributing factors of target and source cities.
