Just looked at WVN vs the 1B divert....
WVN currently has 5 AM trips and 7 PM trips, between 15.20 and 18.20.
1B will provide 4 AM trips and just THREE afternoon trips, covering 16.58 and 17.48.
That's hardly a "service improvement" as Arriva are calling it!
The wyvern service is an oddity. Currently WYN has 5 outbound trips every 30 minutes between 7.05 and 9.05, and 7 inbound trips between 15.20 and 18.20 Monday to Friday.
1B will have outbound trips at 7.30, 7.50, 8.10 and 8.35 and inbound trips at 16.58, 17.23 and 17.48.
I guess the starkest thing is the evening service starting over an hour and a half later, on an already very limited service, but I would guess that reflects demand.
It is a relatively small business park next to a retail park. Other services have been ran and failed it previous years which implies there is limited demand.
I guess the logic behind diverted a few 1b services at times against, the peak flow of customers makes some sense, but it does just meet a current demand rather than trying to expand the market. Peak time 20x as an alternative however would meet the current demand and offer faster links from Spondon to Derby and new links to Wyvern, Pride Park and Derby Railway Station from Spondon.
The need to change buses to reach your final destination deters people from using public transport and increases use of taxis.
