The long-haul vs. commuter traffic conflict

A problem is occurring on roads intended as long-haul links with other parts of the Province - such as the Trans Canada Highway between the Port Mann Bridge and Chilliwack. These roads are acting as conduits for urban sprawl and are increasingly losing their function for long-haul traffic. They are instead providing commuter capacity for outlying areas where there is affordable housing, but this is occurring through the pre-emption of long-haul transport capacity at the provincial taxpayer’s expense and that of the overall economy. Some roads (such as the King George Highway in Surrey, or the Lougheed Highway through Burnaby) have already reached the point where they have lost their original function and have been surrendered to local or intra-regional traffic. But it is not too late to protect critical sections (e.g. of the Trans Canada Highway) which lie outside the currently urbanized area. The proposed solution to this problem is to restrain tightly all single-occupant vehicles commuting from the valley towns (such as Langley, Abbotsford, Matsqui, Maple Ridge, Mission and Chilliwack) into the urban areas. Long-haul road capacity should be rationed by limiting access onto the inter-regional links, e.g. by:
- charging deterrent tolls at or near on-ramps at the valley towns, large enough to cut down demand; and/or
- restricting access through computerized, coordinated traffic lights at on-ramps; these would feed vehicles into the traffic flow at a rate which maintains travel speeds and prevents congestion from developing on the long-haul facility.
This approach represents a dramatic reversal of past practice, which would typically suggest a major widening of roads such as the Trans Canada Highway for mixed traffic, and improving interchanges to give better access to the rapidly growing valley towns.
Such an approach is also consistent with a policy of using transportation to help shape the target land-use plan, since it reduces in relative terms the accessibility of areas - the valley towns - which the growth management proposals suggest should follow a less-than-trend growth rate.
It is important to note that the proposed solutions will fail unless the change in supply policy is enunciated clearly, applied consistently for decades, and backed by parallel municipal land-use controls, acre-by-acre, in the valley towns.
