  •  There's still too little room, Bruce... (0+ / 0-)

    ...even on a street like Western, with a 100' ROW in some places. And where the CTA and CDOT tried out bus priority, they did it with express bus routes, all of which have been eliminated in the last round of budget cuts. The space and money just aren't there.

      ... given as 86 feet for travel segments and 97 feet for station segments.

      They recognize that most Chicago streets do not have room for the layout of a sidewalk each way, cycle path each way, parking each way, traffic lane each way, and BRT lane each way, and their methodology steps through segment by segment.

      As far as money, this is not a diary on funding. Of course under existing systems, the money is only available to do things existing ways, and the vested interests who are vested interests because they benefit from the existing ways of doing things see to it that technologies that threaten to disrupt the status quo are starved of funds.

      On the other hand, City of Chicago property developers and a range of other Chicago business interests do not have a vested interest in going down with the Big Oil and RoadEmpire vested interests, which is how the MTC ends up proposing a $1b+ network of ten BRT corridors comprising nearly 100 miles of corridor.

        ...to seek busways on abandonned railroad rights-of-way, which there are a lot of in this town. Me? I'm out of the game, and in 2 years, out of the City and living on our farm.

          ... around both constructability and viability as a transit corridor.

          I am not sure how you think a sidewalk on each side, parking on each side, a cycle lane on each side, a traffic lane on each side and a transit lane on each side adds up to 100 ft. or more.

          •  Well, I used to design traffic signal... (0+ / 0-)

            ...improvements, as part of my old job with the CIty. And between having access to pavement marking drawings, existing traffic signal cable plans, and actually going out and doing measurements with a wheel, I've seen fair portions of the arterial street grid in Chicago over the years, and am familiar with how wide most of those streets are. I will continue to contend that much of it just is not wide enough to support BRT without either creating too much congestion in the existing roadway, or spending huge sums to acquire property and substantially widen the roadway. But, as I said before, paper is cheaper than asphalt. It was true back in the 1920's, when a subway was proposed under Western Avenue, running the length of the City.

            •  What do you mean by ... (0+ / 0-)

              ... "creating too much congestion in the existing roadway"?

              Are you assuming a minimum of more than one lane of general traffic each way? As I've said (and shown), the MTC layout has one traffic lane each way. The segments with BRT stations also guarantee allowance for a left turn intersection lane, since those segments need to be an extra 11ft wide to accomodate the stations at the side of the BRT lanes in the middle of the street.
