BOSTON & DISTRICT BYPASS PRESSURE GROUP

   

Traffic Timing Survey:

December 2005 – February 2006
 

 

BBPG

 Traffic Survey

  

Summary

 

This survey was undertaken to establish the time it took to travel between Pilgrim Hospital Roundabout and Tesco Roundabout. Forty-four per cent of journeys took more than 20 minutes with an average of 21.92 and a range of 6 – 46 minutes, to cover the 3.1 miles via John Adams way or 3.6 miles via Sluice Bridge.

The results of several variable factors included in the survey are included but because of the small numbers, the results are not statistically significant but may be interesting for future study.

 

BBPG Traffic Survey December 2005 – February 2006

 

 

INTRODUCTION

 

Boston is a typical small market town in the fens with a road system designed and built for a bygone age of slow moving traffic. The town sits on the banks of the river Witham dividing the town in half, with two bridges linking the north and south banks which are the only means of driving through the town.

 

Boston’s economy is supported by two main industries: agriculture, in an area where a large amount of the countries vegetables are either grown or processed and an active dock. Boston is also on the main route used by holiday traffic from the Midlands heading for the Lincolnshire coastal resorts. Associated with these three traffic user groups are locally and internationally owned Juggernauts (some with trailers), slow moving tractors and cars towing caravans, all of which take more space, have longer stopping distances and are slower to accelerate from a standing start.

 

Added to the traffic problem is the fact that all the large retail outlets and supermarkets are sited on the south side of the town which necessitates half the population crossing the town to shop, whilst the largest employer Pilgrim Hospital and majority of the schools are located on the north side. Furthermore, public transport is poor and is inappropriate for people making bulky or heavy purchases.  A car is important in a rural area if one is to have full access to local facilities and essential if one lives in a surrounding village, has small children, is elderly or disabled.

 

This survey therefore was carried out because it is perceived that the 3 miles journey from one side of the town to the other takes far too long. The cause of the delays are  variously blamed by local people on the number of traffic lights, the bridges, the numbers of heavy good vehicles and the siting of the new ASDA in an already busy part of town.

 

The aim of this survey was simply to establish the average time taken to drive the distance between Pilgrim Hospital roundabout (Pilgrim), and Tesco roundabout (Tesco), using either John Adams Way (JAW), or the Sluice Bridge (SB).

 

Within the survey we chose to also look at variables which might affect the time taken on these journeys including the: time of day, day of the week, the route and road conditions. The survey form was designed to discover which, if any, of these factors might be of significance.

 

 

RESULTS

 

50 journeys are included which were surveyed between 15.12.05 and 12.02.2006

Routes

 

There are 4 routes within this survey:

 

a)  Pilgrim to Tesco via JAW

b)  Pilgrim to Tesco via SB

c)  Tesco to Pilgrim via JAW

d)  Tesco to Pilgrim via SB

 

The distance: The distance between Pilgrim and Tesco is:

 

                        Pilgrim to Tesco via JAW    3.1 miles

                        Pilgrim to Tesco via SB       3.6 miles

 

Traffic control measures:

 

            TL        Traffic lights (including those on 2 roundabouts)

            TLP     Traffic lights with added pedestrian programmed crossing facility

            PC       Pelican crossings with pedestrians activated lights

            LC **  Level crossings with lights activated when trains are due

            RA       Roundabouts

 

 

**Level crossings

These are of some significance when travelling through Boston since  there are 32 trains scheduled to stop at Boston  station on weekdays (Central Trains Guide 3, 11 December 2005 to 10 June 2006) and these trains cross all 3  level crossings, 2 of which  affect either route.
