TRIAL RUN

Q: This is such a huge undertaking that it’s common sense to set up a trial run to ensure this will work. 

A: We do not have the ability to conduct a demonstration project that would put all the pieces accurately together. We are moving toward 75% design details based on the volume of study, community input, community goal setting, and engineering expertise regarding road diet and safety improvements.  

There is no part of the Picture Main Street design that will be implemented for the first time with this project. These are tried and true strategies that have been tested by engineering experts all over the country. Northampton is not the first municipality to implement this type of roadway redesign. Similar implementations have occurred throughout the Commonwealth, and the design and solutions have been thoroughly tested and proven effective. 

For example, there are existing downtown streets in Northampton with greater traffic volumes than Main Street that have two lanes with parallel parking (King Street, Lower Main Street, Pleasant Street), which shows us that traffic can be accommodated and function with emergency access.

The proposed redesign is not just about physical changes to the street. The project involves interrelated measures that would be impossible to implement in a trial run. Some of these measures would require long lead times. If we only do the easy stuff and leave out important elements, a trial run will not show how the system will actually work. Rather, it will be a waste of time and money. 

Aside from the technical reasons why this won’t work listed below, it takes time for people to get used to using a new layout and to develop new habits. The period of a trial run would be a little like the first week of actual plan implementation, only worse. Think about the roundabouts that have been successfully implemented here and elsewhere. When they were first proposed, many people were horrified and were convinced they wouldn't work. And when they first went in, there was plenty of confusion as people struggled to learn how to navigate them. We all know that the roundabout at the Coolidge Bridge has forever changed Friday afternoon coming from Amherst. 

To further explain why a trial run is not simply a low-cost matter of placing cones in the street to see how it works, here are just some of the specific measures that would have to be part of a realistic trial run:

  1. Signal timing - one of the main causes of congestion on Main Street is the timing of traffic lights. Changing signal timing involves engineering analysis and the acquisition and installation of new signal modules. Further, the location of some of the signals will be changing to allow for more queue space, which is also tied to the engineering of the signal timing. Such significant changes are not feasible as a trial.
  2. Special zones - for loading and accessible access require approvals that would be hard to obtain and implement on a trial basis and require planned accessibility improvements that can’t be done temporarily. The plan addresses the need for safe access for people with different abilities.
  3. Signage – any changes must be accompanied by clear signage. This requires significant planning and fabrication for which there is no current budget. However, this will be included in the MassDOT-funded project.  
  4. Restriping for vehicles, bike/ped zones - this must be done clearly and understandably and is not possible to do as a temporary measure, as it will involve measurements based on changed road geometry.
  5. To simulate the three-lane design, the median islands on Main Street would have to be removed for the trial period and then put back afterward. This would require demolition and reconstruction of infrastructure.

Thus a trial run cannot be developed to accomplish what is intended by the Picture Main Street design. However, we have dozens of examples of these treatments being implemented successfully elsewhere. 

That being said, one component of the Picture Main Street design has been successfully tested for the last three years - see FAQ PARKING, A4.
