To promote more housing, cities and states target parking minimums • Stateline
In 1923, the city of Columbus, Ohio, enacted the first known off-street parking requirement for new apartment buildings. The city’s rules got stricter over time. In 1954, a Columbus apartment building with 100 one-bedroom units had to have at least 100 parking spaces; by 2022, the minimum was 150. For a 2,500-square-foot restaurant, the mandate grew […]
Urban congestion relief experiments through routing-app interventions
Traffic congestion remains a persistent challenge for urban mobility, increasing travel delays and elevating CO2 emissions. The widespread use of smartphones and GPS navigation creates new opportunities to mitigate congestion through routing optimizations in apps, yet real-world evidence for the effectiveness of such interventions is limited. Here we report large-scale empirical experiments evaluating routing-based traffic interventions on ~100 highly congested road segments across 10 major US cities. By rerouting a small share of Google Maps trips from targeted congested highway and arterial segments to less congested alternatives of equivalent road-classes with comparable travel times, we observe a city-average 2% increase in vehicle speeds on the intervened segments, along with improved travel times 0.7% and potential annual reductions exceeding 1,000 tons of CO2-equivalent emissions per city in the majority of studied locations. These findings provide evidence that marginal routing interventions involving a small proportion of vehicles can measurably enhance overall road network efficiency, offering a practical pathway to easing congestion and advancing urban sustainability.
National Park Service: Public Use of the National Park System (1872-2000): Chapter 9
The first part of this section reviews basic ideas for dispersing visitors outside the System. While merit is seen in some of these ideas, the conclusion is reached that at best they can make only a limited contribution to regulating mounting park travel because there is no substitute for a visit to a national park. The second part of this section then reviews concepts and methods for regulating public use inside the parks through park developments, land classification, including wilderness area designations, and vehicular controls, including new transportation systems.
