TRANSPORTATION'S BIGGEST PROBLEM
The big problem with all surface transportation systems is that when they fit into neighborhood environments and provide first/last mile service, they have limited speed and capacity. When they have high speed and capacity, they no longer fit into neighborhoods or provide first/last mile service. Automated transit networks (ATN) are the exception to this rule.
Because all intersections are merges or diverges with no crossovers, guideway traffic never stops. This continual flow provides good capacity at high average speeds. There is little or no distinction between minor and major guideways like we have between neighborhood streets, highways, and freeways. There are no stop streets, traffic lights or traffic jams.
This means that an ATN network with stations scattered throughout a community can provide both first/last mile service and high speed and capacity. One small limitation is that walking a quarter of a mile or less will be required, although the system should provide room for micro transit such as bikes or scooters.
While there will always be some resistance to elevated guideways along neighborhood streets, it is believed that this can be overcome by elegant designs. Locating the guideway over the roadway can reduce the impact to some tree trimming. Noise and vibration impacts will be almost non-existent.
Finally, one transportation system that can provide great service throughout a community with no need to transfer or make unnecessary stops.
