The signalized intersection between Highway 12 and Pine Street in Ontario, Canada has faced some challenges in its current design. Therefore, future analysis and design of the intersection should incorporate an appropriate sustainability indicator to ensure that the intersection remains functional as a long-term solution. Perhaps the most important sustainability indicators for future analysis or evaluation of the intersection should be traffic demand as well as future population (Litman 12). These sustainability indicators will ensure the intersection remains safe and operating at an optimal level for the future, based on how it is designed today. The biggest challenge the intersection has faced is traffic congestion due to the high number of vehicles using it. he. Traffic jams made the intersection unviable due to wasted fuel and time (Kockelman and Shabih 17). Future intersection design can be either sustainable or unsustainable, depending on the strategies used to overcome this challenge. For example, widening the intersection to reduce traffic congestion may be unsustainable (Litman 13). Indeed, the process will be costly and therefore unprofitable. Expanding the signalized intersection will also be a challenge due to the current layout of the site. Several expensive buildings on both Highway 12 and Pine Street will need to be demolished to clear the way for the expansion. On the other hand, transforming the intersection into a roundabout can be sustainable as there will be an increase in mobility and efficiency of vehicle travel. There needs to be a change in the design because the current intersection, which is a four-way intersection, has 32 con...... middle of paper ......rental design. This will make the surrounding people feel appreciated by the new assessment.
