Curb Bus Lane

• Enhances bus speeds and reliability by keeping buses separate from mixed traffic congestion and reducing the need for buses to merge at bus stops
• Maintains vehicular travel lanes while optimizing curb space
• Often allows for parking or loading during off-peak hours, balancing transit and access needs
• Provides space for emergency vehicles to bypass traffic, improving response times

• Removes parking and may impact curb access 
• Enforcement can be challenging if curb demand for other uses is high

• Consider on all streets with high bus volumes or bus ridership and adequate roadway width
• Avoid on streets where the roadway geometry prevents the safe operation of a bus lane in conjunction with other necessary uses of the roadway
• Streets with minimal curb demand
• Use a curbside bus lane when right-of-way may be constrained and where parking impacts can be managed, otherwise use Offset Bus Lane

Review Markings

• Minimum of 11 feet in width
• Color Surface Treatment is preferred when bus lane regulations are in effect for at least six hours per day
• For curbside bus lanes, curbside deliveries can be accommodated with truck loading windows or dedicated truck loading at nearby locations
• Can be combined with an Offset Bus Lane to provide a double bus lane (typically 21-24 feet in width)
• Can also be implemented as a contraflow lane where conditions are appropriate (typically 12- 14 feet in width) 
• Automated enforcement is used to keep bus lanes clear
