Transit and TDM Recommended ConceptsTransit and TDM Recommended Concepts

Goal: divert vehicle trips that would otherwise go throughthe Route 9, Damon Rd, and Interchange 19 intersection.

TDM projects identified in Connecticut River Crossing Study

(2004)

Update to reflect projects implemented or planned since

then.Taking into account:

License plate survey

Intersection delay dataAvailable transit, bicycle, and pedestrian data

Transit and TDM Concepts-Route 9 Express BusTransit and TDM Concepts-Route 9 Express Bus


69/79


Transit and TDM Concepts Route 9 Express Busp p

M40 - Route 9 Express

1. Afternoon service is overcrowded. Increasing frequency fromevery 30 minutes to every 20 minutes is warranted.

2. Sheldon Field lot is not yet at capacity.

3. Extending service to V.A. Hospital in Leeds would not attractridership while Sheldon Field lot has space available, especially

since all-day service would not be available at the new P&R.

4. Alternate route via Bridge Road-Damon Road would not savemuch travel time and would bypass major ridership generators.

Transit and TDM Concepts-Route 9 Local BusTransit and TDM Concepts-Route 9 Local Bus

a s t a d Co cepts oute 9 oca usp

B43 Route 9 Local Bus

1. Reduce headway between trips to reduce crowding and improveservice:

20 minutes to 10 minutes 6 am to 5 pm

30 minutes to 15 minutes 5 pm to 8 pm

45 minutes to 20 minutes 8 pm to end of service

2. Extension west to serve Cooley Dickinson Hospital Not recommended because there is not much demand from employees

and other potential riders in Hadley & Amherst

Other riders already served by route R42 (frequency could be improvedto hourly)

Transit and TDM Concepts-Transit Signal Priority (TSP)Transit and TDM Concepts-Transit Signal Priority (TSP)


71/79


p g y ( )p g y ( )

Implement TSP

Every intersection on Rt 9 from Rts 5 & 10 in Northampton toUniversity Drive in Amherst

Assume aggressive TSP reduces average bus delay to 5seconds per signal

Do not implement TSP

Prospect St to New South St/ State St, Northampton

Closely spaced signals are coordinated.

Time SavingsBus routes B43 and M40: 5 min

Bus route 39: 2 min (turns at Bay Road)

Winter maintenance of Norwottuck Rail Trail

To improve bicycle access to businesses, add signal, Rt 9 at

West St, Hadley, to permit movement from Norwottuck Trail

to south side of West St and Route 9

To improve bicycle access to Hampshire Mall, reconfigure

South Maple St, Norwottuck Trail to Rt 9, from 4 to 3 lanes (1wide in each direction plus center left turn).
