Round 9

Designing a Fair Curb-Use Policy

A fictional mid-sized city must revise how limited curb space is allocated among residents, deliveries, small businesses, transit access, accessibility needs, and short-term parking. The goal is to improve mobility and local economic activity while keeping the system understandable, enforceable, and fair across neighborhoods. The city can make only modest infrastructure investments, must preserve reliable access for people with disabilities and essential services, and wants to evaluate results within two years. Experts disagree about whether the policy should prioritize flexibility, predictable access, market-like pricing, or neighborhood control.
