Why Monorail can be up to Three Times Faster in Dense Urban Areas
We now present a simple model showing the positive effects of Monorail being able to achieve a faster maximum speed in dense urban areas.
This route is our 'Red' line which bypasses IH35 along Lamar, Guadalupe, Lavaca, South First, and South Congress. We assume that the Monorail vehicle accelerates at 2.8 MPH/s until it reaches any one of the following maximum speeds. It then decelerates at the same rate in time to reach the next station, where it dwells for 30 seconds. Each passenger is assumed to travel for 6 stops, which is approximately the number of stops from one end of the line to the center, thus simulating a typical commute into the central business district. We then examine the effects of maximum system speed on average speed, average passenger trip time, the total number of trains required and the total number of passengers per hour per direction (pphpd) carried by the system.
Keep in mind as you read the chart above that the national average light rail speed (FY2000) was 15.3 MPH in 2000 (source: American Public Transportation Association: Light Rail Summary Data, FY2000. This would put a light rail vehicle somewhere in the left side of each graph below compared to the Monorail which we will assume has a maximum system speed of 55 MPH. This leads to the following conclusions:
