Advancements in sensor and emissions technology would ensure that the new and improved Transitway would be a success. Buses could be equipped with red-light sensors, which would change the light ahead of them as they approach, so that service would be timely and frequent. The newest hybrid SEPTA buses, as well as the all-electric Proterra buses slated to begin service on other routes, do not pollute the air as older buses did, and their engines are much quieter than previous generations of buses. These advancements add up to cleaner air, less noise, and the ability to increase bus frequency, which were the major complaints that made the Transitway’s previous iteration unsuccessful.
