A road diet is a tactic used by engineers and planners to improve pedestrian and bicyclist mobility and safety by reducing conflicts between motor vehicles. It typically involves converting a four-lane roadway to a three-lane roadway with a center turn lane and adding sidewalks and/or bicycle lanes. While some people are resistant to the idea of road diets, citing concerns about traffic flow and congestion, others argue that they improve safety and mobility for all road users. A recent study recommends that Louisville continue its road diet projects to reduce crashes and pedestrian collisions, and some people on Reddit have noticed improvements on roads like Bardstown Road and Eastern Parkway. It is not clear, however, if and when a road diet will be implemented on Lexington Rd.

What You'll Learn

Public acceptance
Gaining public acceptance for road diets is crucial but can be challenging. Without the support of residents and business owners, the project may not go through or may be criticised if implemented. Common concerns include the impact on traffic flow, congestion, cost, increased traffic on neighbourhood streets, and access to and from driveways and side streets. However, these concerns can be addressed by transportation agencies through data and success stories where road diets have improved mobility for all road users.
For example, in Louisville, a study recommends continuing road diet projects to reduce crashes and pedestrian collisions. While some residents express confusion and resistance to change, others have noted improvements in safety and traffic flow on roads such as Bardstown Road and Eastern Parkway. One resident observed that the road diet has dramatically improved walkability and overall safety in their area over the past two decades.
Road diets typically involve converting a four-lane undivided roadway to a three-lane roadway with a centre two-way left-turn lane. This configuration has been shown to reduce crashes, improve mobility, and enhance overall quality of life. For instance, in Seattle, Peter Lagerwey, the former coordinator of the city's pedestrian and bicycle program, found that removing left turns from travel lanes improved efficiency and reduced congestion.
To address concerns about increased traffic on neighbourhood streets, transportation agencies can monitor traffic in the affected areas before and after the road diet implementation to determine if diverted traffic causes any issues. Additionally, road diets can be implemented in conjunction with other projects, such as pavement overlays, to reduce costs and improve safety.
Overall, while gaining public acceptance for road diets can be challenging, providing data, success stories, and addressing specific concerns can help build support for these projects, which have the potential to improve safety, mobility, and quality of life for all road users.

Traffic flow
A road diet typically involves converting a four-lane roadway (two lanes in each direction) to a three-lane configuration with one lane in each direction and a centre turn lane. This reconfiguration can be achieved through lane restriping and, when implemented appropriately, traffic flow can remain relatively unchanged or even improved. For example, by removing left turns from travel lanes, efficiency can be increased.
In the case of Lexington Rd, the road diet approach aims to address safety concerns and reduce crashes and pedestrian collisions. While some individuals express concerns about lane removal and restricted flow, evidence suggests that reducing road widths can cause drivers to slow down and lead to improved safety. Additionally, fewer lanes mean fewer opportunities for accidents caused by lane changes and passing.
The success of road diets in improving traffic flow has been observed in other areas as well. For instance, the stretch between UofL and Barret, where the implementation of a road diet has resulted in improved safety and traffic flow. While some may be resistant to change, the benefits of improved walkability and safety are significant.
To address concerns about traffic flow, transportation agencies can provide success stories and case studies from various states where road diets have been successfully implemented. By monitoring traffic before and after the implementation, agencies can also assess the impact on diverted traffic and address any potential issues. Overall, when done correctly, road diets can enhance traffic flow and improve safety for all road users.

Safety
The road diet approach typically involves converting a four-lane roadway (two lanes in each direction) to a three-lane configuration with one lane in each direction and a central turning lane. This reconfiguration can be done by restriping lanes, often in conjunction with a resurfacing project, and can be a low-cost safety solution. It is generally considered suitable for roads with a daily traffic volume of 25,000 vehicles or less.
The benefits of implementing a road diet on Lexington Rd could include a reduction in crashes and collisions. By dedicating a central turning lane, rear-end and left-turn crashes could be reduced. The number of right-angle crashes could also decrease as motorists crossing from side streets would only need to navigate three lanes of traffic instead of four. Additionally, pedestrians would have fewer lanes to cross, improving safety.
Furthermore, narrowing travel lanes or removing lanes altogether can cause drivers to slow down, leading to safer driving speeds. This can be further enhanced by adding visual elements closer to the road. With fewer lanes, there are also fewer opportunities for lane changes and passing, which are common causes of accidents.
While some stakeholders may express concerns about increased congestion and diverted traffic, these issues can be mitigated with careful planning and monitoring. For example, removing left turns from travel lanes can improve efficiency, and traffic can be monitored before and after implementation to address any problems caused by diverted traffic. Gaining public acceptance is crucial, and transportation agencies can address concerns by highlighting success stories where road diets have improved mobility for all road users without negatively impacting traffic flow.

Congestion
A road diet is a strategy used by engineers and planners to improve pedestrian and bicyclist mobility, enhance safety, and revitalise downtown areas. It typically involves converting a four-lane road (two lanes in each direction) into a three-lane road with one lane in each direction and a central turning lane. This reconfiguration can also include the addition of sidewalks and bicycle lanes.
One of the primary concerns associated with implementing a road diet is the potential impact on congestion and traffic flow. Residents and business owners worry that reducing the number of lanes will restrict traffic flow and cause increased congestion. However, studies and case reports from various states suggest that these problems do not usually occur. For example, a user on Reddit mentions that they have experienced improved safety and traffic flow on roads that have implemented road diets.
To address concerns about congestion, transportation agencies can highlight success stories where road diets have improved mobility for all road users. For instance, by removing left turns from travel lanes, SDOT (State Department of Transportation) has found an actual gain in efficiency, countering the notion that road diets cause congestion. Additionally, road diets can calm traffic and enhance overall quality of life by improving safety and mobility for all road users, including pedestrians and bicyclists.
Furthermore, road diets can lead to a reduction in the number of vehicles on the road. By providing dedicated infrastructure for bicyclists, such as bike lanes and cycling paths, more people may be encouraged to cycle, resulting in fewer cars on the road. This, in turn, can help alleviate congestion and improve traffic flow. Proper bicycle infrastructure can also improve safety for cyclists, making roads with road diets safer for all users.
While the potential for increased congestion is a valid concern, studies and real-world examples suggest that road diets can improve traffic flow and mobility without causing significant backups. By providing dedicated turning lanes, reducing lane-changing opportunities, and improving safety for all road users, road diets can enhance overall traffic efficiency while also creating space for bicyclists and pedestrians.

Cost
The cost of implementing a road diet is a significant consideration for transportation agencies. While a road diet can be a low-cost safety solution when combined with a simple pavement overlay, it is important to consider the potential costs associated with reconfiguring roadways and addressing stakeholder concerns.
One of the primary costs associated with a road diet is the physical reconfiguration of the roadway. This may include narrowing travel lanes or shoulders, eliminating lanes, and adding new infrastructure such as sidewalks, bicycle lanes, turning lanes, bus lanes, parking spaces, and buffers. In some cases, the reconfiguration can be accomplished at a low cost by simply restriping the lanes during a resurfacing project. However, in other cases, more extensive construction may be required, which could increase the cost significantly.
The volume of traffic on the roadway is also a factor in the cost of a road diet. Roads with a high volume of traffic may require more complex and costly solutions to manage the same number of vehicles on a reduced number of lanes. This could include the addition of turning lanes or other traffic management strategies to improve efficiency and reduce congestion.
Another cost consideration is the potential impact on local businesses and residents. Without their support, the road diet may face opposition or criticism. Transportation agencies may need to invest in public relations or community engagement initiatives to address concerns about the impact on traffic flow, congestion, and access to driveways and side streets.
Finally, the cost of monitoring and evaluating the effectiveness of the road diet should be considered. Transportation agencies may need to collect data and conduct studies before and after the implementation to determine the impact on traffic flow, safety, and other factors. This data can help address stakeholder concerns and make adjustments as needed to ensure the success of the road diet.
Overall, while a road diet can be a low-cost solution in some cases, there are a number of factors that can impact the cost, and careful planning and consideration of these factors are necessary to ensure a successful outcome.
