Bus services are known to offer flexibility and low capital cost. With recent technological advancements such as transit priority and BRT, cities are seeing their [ridership increase](https://www.governing.com/transportation/more-riders-fewer-stations-for-intercity-bus-lines) with other positive gains as well. Today, we will explore the upsides and the downsides of Bus Rapid Transit systems and the impact bus-only lanes can have in your city. ## **First, what is a BRT (Bus Rapid Transit) system?** Combining the pros of a train – more passengers – with the adaptability of a bus – less infrastructure required – a Bus Rapid Transit (BRT) system employs a more extended bus in dedicated bus lanes to move passengers around urban environments. Known to provide faster and more efficient service to transit users, the[Federal Transit Administration](https://www.transit.dot.gov/research-innovation/bus-rapid-transit) describes BRT systems as a combination of dedicated lanes, busways, [traffic signal priority technological solutions](https://lyt.ai/press-release/lyt-introduces-new-transit-signal-prioritization-insights-platform-for-local-transit-agencies/), off-board fare collection, elevated platforms, and enhanced stations. By intertwining both the elements of rail and bus travel and bus lanes, BRT is utilized increasingly in heavily congested urban spaces. The travel medium is also viewed as a more modern transit solution. Below, we have put together a list of both the pros and cons of utilizing a BRT system. ## **5 Benefits (Pros) of Bus Rapid Transit Lanes** Below are five benefits of BRT systems with the use of bus lanes: ### **1. Reliability** Reliability is a common issue amongst public transit users. With dedicated lanes for BRTs, urban areas can reduce the impact of traffic congestion on buses, leading to more predictable schedules and increased reliability for commuters. More satisfied riders lead to increased ridership and efficiency over time. ### **2. Efficient Travel & Speed** Not only does BRT increase the travel times for riders, but it can also help other motorists by reducing traffic congestion by removing buses from traffic lanes and providing them with dedicated lanes. The aforementioned reliability is produced in large part by the speed at which BRT systems can operate. ### **3. Encourages Public Transit Ridership** The downside to public transport is often the lack of reliability and the time in it takes to get from point A to B. However, BRT systems can increase ridership because they utilize transit lanes. By increasing the speed and reliability, ridership has the potential to increase, leading to other net positive gains. ### **4. Positive Environmental Impact** Simply put, the increased use of public transit reduces the number of individual vehicles on the road. Over the long haul, this contributes to lower emissions and improved air quality in urban areas. Utilizing BRT can help cities reach their CO2 emission goals. The results can be outstanding when BRT lanes are used in conjunction with technology. With the help of LYT.transit, [TriMet’s new FX2 Route](https://lyt.ai/customer-success-stories/moving-10000-trimet-riders-a-day-in-portland/) saw savings of almost 1,150 metric tons of CO2 removed in one year. ### **5. Economic Development** Improving the accessibility to businesses and job centers is possible with the use of BRT. Riders can access other city areas with the ease and reliability BRT provides. Over the long haul, it can attract investment into otherwise left-aside areas. ## **The Downside (5 Cons) of Bus Rapid Transit Lanes** While the upside BRT systems can deliver doesn’t go unnoticed, several factors can also cause concern. *Below are the five cons of BRT systems:* ### **1. Implementation Challenges** The first downside to Bus Rapid Transit usage is the need to install bus lanes. With dedicated transit lanes, the effectiveness of BRT can be manageable. However, from installing curbside bus lanes to reconfiguring traffic patterns, a bus-only lane can exacerbate congestion for the general traffic lanes. While one upside is economic development, another downside to a new BRT system is the capital impact of creating new transit lanes. Luckily, with [**LYT.transit**](https://lyt.ai/solutions/lyt-transit/), artificial intelligence and machine learning can help keep buses on time without installing new bus lanes.  ### **2. Costly Infrastructure Upgrades** The capital mentioned above impact of BRT often comes in the form of heavy infrastructure upgrades that some BRT systems may require. While some cities are more equipped to handle a new or revamped public transit system, others needing bus-only lanes may have to see a massive overhaul, which can often be viewed as costly. The upfront costs are still significantly less that laying rails for metro systems. This is why your city’s discovery process should be detailed to figure out the economic impact. Also, bridges create bottlenecks for all traffic since most freeway bridges were built over 50+ years ago. Since bridges have limited ability to add additional lanes, installation of BRT lanes and bicycle lanes can have an adverse effect on general-purpose traffic as congestion increases. Not to mention, the cost of adding additional bridge lanes can be astronomical.  ### **3. Negative Impact on Traffic** The traveling public frequently finds the quality of bus service provided in urban centers could be better due to slow-moving buses, frequent stops, and traffic delays. Curbside lanes and median lanes can cause turning traffic congestion, and exclusive lanes for BRTs may speed up public transportation, but at the cost of slowing down general traffic lanes. ### **4. Discontent from Drivers** Imagine letting your city residents know that with new bus lanes, they can expect to see their commute times increase. Support would quickly move in the opposite direction if this were the case, and unfortunately, in some cities, existing travel lanes cannot meet the demand of daily commuters as it is. A travel lane reserved explicitly for public transport could cause many motorists to resist the idea. ### **5. Equity of Tax Dollars:** While meeting public transport passenger demand can increase ridership, a downside is an issue with equity in tax allocation. A bus-only lane benefits the bus-only riders. Other traffic may see this as inequitable. Furthermore, business access provides opportunities but can cause other secondary issues that sometimes need to be accounted for. ## **Solutions to Consider** Implementing transit-only lanes for buses is a complex decision that requires careful consideration of various factors, including your city’s unique needs, budgets, and policies. While a bus-only lane may sound promising in theory, in application, your planning team will need to consider numerous elements, from traffic congestion to existing travel lanes. Working within the space of reducing carbon output, increasing the speed and reliability of existing public transport systems, and meeting the needs of your city’s residents, there are alternative transit solutions that are worth considering. **Transit Signal Priority (TSP)** moves transit vehicles through congested intersections faster and safer, utilizing signal priority technology. TSP can be used as a stand-alone solution or in conjunction with bus-only lanes to assist the efficiency of bus routes/dedicated lanes while providing transit vehicles with consistent priority. Harnessing the power of a single-edge device installed in your Traffic Management Center (TMC), LYT.transit assists transit vehicles with a reliable green light for every transit vehicle, more affordably than other solutions.
